far superior in performance

Road Fabrics Asphalt Overlay System is far superior in performance to thicker ACC sections. Comparative test sections have been monitored since 1979 for reflective cracking, waterproofing and fatigue life. It has been observed that, regarding reflective cracking, the Road Fabrics Asphalt Overlay System is equivalent to a minimum 1.2 inches of additional ACC. As a waterproofing layer, the Asphalt Overlay System is more durable and effective. When included in an overlay, the Road Fabrics System can prolong the overlay fatigue life anywhere from 50% to 200%. It should be noted that, in some cases, additional ACC thickness is required to overcome structural deficiencies. But in a strict cost comparison, Road Fabrics Overlay System is less than half the cost of an additional 1.2 inches of ACC.

Additional FeaturesUnder certain conditions, the Road Fabrics Asphalt Overlay System can improve the fatigue life of the road ten times over non-reinforced pavement. It is resistant to punctures and tears during road construction, and forms a long-lasting waterproof barrier by combining with paving grade asphalt. Road Fabrics Asphalt Overlay Fabric is resistant to various chemicals and is rot-free.

Asphalt DistributionThe distributor should have a positive shut-off valve. It needs to be metered and able to apply the asphalt sealant uniformly at a prescribed rate. The project engineer should require that the equipment be tested off-site prior to the application to confirm proper set-up and performance. Photo A.

Fabric Laydown EquipmentLaydown of the fabric can be accomplished manually or by means of mechanical equipment. If mechanical laydown equipment is used, it should have the capacity to dispense a full roll of fabric. The equipment must lay the fabric smoothly without causing folds or wrinkles.

Equipment

Surface PreparationThe surface should be clean, dry and free of vegetation. Filler, suitable to the surface, should be used to fill small cracks ¼ inch or larger. Use a hot mix, slurry or other suitable filler to repair larger holes or cracks. It should be noted that the fabric should not be applied until the fillers cure. Deteriorated or rough pavement may require a leveling course prior to the application of the Asphalt Overlay Fabric.

Application of SealantUsing distributor equipment, spray apply the asphaltic sealant uniformly at the specified rate. Hand spraying is not recommended. Asphalt temperature is critical to ensure a uniform spray pattern. Minimum temperature for asphalt cements is 290º F. If the fabric itself is to be over sprayed, do not exceed 325º F for PG 64-22 or damage to the fabric may occur. It is important to list the asphalt sealant as a separate bid item. Photo B.

Asphalt sealant should be applied 2 to 6 inches wider than the width of the fabric. Fabric movement is possible in areas of excess asphalt, so any drools or spills should be cleaned from the road surface.

Fabric PlacementBefore the asphalt has cooled and tackiness is lost, the fabric should be placed on to the asphaltic sealant while making sure wrinkles are kept to a minimum. If any severe wrinkles or folds do occur, they should be slit and laid down flat. To maximize fabric contact with the pavement surface, brooming or pneumatic rolling is performed. Rolling will flatten most small wrinkles and prevent them from effecting performance. Fabric joints should overlap 1 to 3 inches to assure full closure. Photo C.

Road Fabrics Inc Pavement Solutions Brochure

Hot Mix OverlayNominal Hot mix overlay thickness should have a minimum thickness of 1.5 inches after compaction. This overlay could be applied immediately following fabric laydown. In some cases, some asphaltic sealant may bleed through the fabric before the application of the hot mix overlay. If this occurs, blot the sealant by spreading hot mix or sand over these areas. By blotting the sealant, the fabric will not as readily be picked up by construction equipment driving over it. Gradual turning of the paver and other vehicles is important to prevent movement or damage to the fabric membrane. Hot mix laydown temperatures are best below 300º F and should not exceed 325º F. Photo D.

Skid ResistanceReducing skid resistance should be a consideration if traffic is allowed on the newly installed Road Fabrics Asphalt Overlay Fabric. Signs and/or flagmen should warn motorists that reduced speed is required and the surface may be slippery when wet. Appropriate signs stating the safe speed limit should be posted in all areas. Other conditions that could further reduce skid resistance are: improper installation, improper tack coat, rainfall or other moisture.

Tack CoatThe asphalt tack coat shall be hot applied asphalt cement meeting grade requirements of AC, AR, or PG specifications. Every effort should be made in order to install paving mat over hot asphalt tack coat. It is recommended that an AC-20, PG 64-22, AR-8000, or a 60-80 penetration grade of asphalt be applied for normal installations and temperatures. For extremely high summertime temperatures higher viscosity asphalt should be used. AC-30, PG 67-22, AR-8000, or 40-60 penetration grades are appropriate.

Asphalt Sealant QuantityPorosity of the surface to be covered and the quantity of residual asphalt

Special Considerations

in the sealant material specified, should govern the asphalt application rate. Depending on pavement condition, application rate may vary from 0.22 to 0.25 gallons per square yard. The fabric alone will absorb at least 0.20 gsy residual asphalt, under heat of the applied overlay. Re-duce the application rate by approximately 20% on steep grades, street intersections and areas where vehicle speed change is common.

Care should be taken in determining the quantity of asphalt which is under the fabric. The membrane must be fully sealed but excessive amounts of asphalt can cause a slippage plane. Asphalt sealants should be compatible to the asphalt used in the hot mix.

On new porous leveling courses, asphalt cements penetrate the surfaces more readily than when used on old pavement. Using a heavier tack coat or pneumatic rolling on the leveling course to create a tight imper-meable surface, can remedy this condition. Use of asphalt emulsions are not recommended.

LimitationsPortland cement concrete slabs may have to be stabilized before ap-plication of the fabric if vertical deflection at the joints has occurred. Otherwise there is risk that reflection of the old cracks may reoccur. In severe climates, thermal cracking may still appear due to expansion and contraction of the overlay itself. Secondary and advanced stages of cracking occur as a result of water infiltration. This type of cracking will be minimized due to the waterproofing properties of the membrane. This makes overlay fabrics valuable even in non-ideal conditions.

RecyclableThere are no problems in drum-dryer recycling, cold milling or sub-sequent paving operations when pavement containing Road Fabrics Asphalt Overlay Fabric is recycled.

Chip Seal with Paving Fabric

increase your chip seals life

Design with Fabric

Whether your chip seal road has high volume of traffic or the occasional car, choose to use Mirafi® Mirapave 500CS chip seal fabric in addition to your normal chip seal procedure. The inclusion of Mirafi® Mirapave 500CS has several benefits to improve the performance of the road and can also increase the chip seal service life by 60%.

Mirafi® Mirapave 500CS acts as a moisture barrier within the pavement and prevents water from penetrating the roadway, which reduces the deterioration of the subgrade due to saturated conditions. Second, the use of Mirafi® Mirapave 500CS improves the bond of the chip seal to the existing roadway and reduces future maintenance needs for the surface. Additionally, saturated paving fabric bridges the filled crack, thus eliminating the need for future crack filling.

Construction with Fabric

The first step in the process entails cleaning the surface and filling any cracks ¼ inch or larger. After the surface is prepared Road Fabrics, Inc. places asphaltic cement, PG 64-22 at a rate of 0.25 gal/yd2. AC placement is directly followed by the installation of the Mirafi® Mirapave 500CS polypropylene paving fabric. The fabric is to be installed void of wrinkles and with a minimum overlap.

Once the fabric is placed, it is recommended you leave the road open to traffic or roll the fabric with a rubber tire roller to allow the PG 64-22 to fully saturate the fabric. Once saturation occurs, you may start the chip seal process with no deviation from your standard chip seal procedure.

For a complete chip seal construction specification and installation guidelines, go to Road Fabrics web site at www.roadfabrics.com.

Mirapave 700 with Polymer Modified Asphaltsuperior performance in ANY climate

Heavier fabrics (≥6oz /Yd2) have shown to have a greater ability to retard reflective cracking than conventional 4oz/ Yd2 paving fabric. Polymer modified liquid asphalt has proven its ability to improve the performance of hot mix asphalt pavements. The combination of a modified liquid asphalt binder and a heavier paving fabric have been proven to increase pavement life in colder regions where pavement environments are harsh. The polymer modified liquid asphalt/paving fabric interlayer system has shown superior performance using polymer modified asphalt binders.

There is a limit as to how many times a pavement can withstand flexural loading before cracking. An overlay in combination with Mirafi’s paving interlayers installed with a polymer modified binder can withstand a higher number of vehicular loadings, improving a pavements overall service life and performance even under today’s heavy traffic loads.

Key benefits:• Increased life in cold climate• Improved resistance to reflective cracking• Moisture barrier• Longer service life

TruPave Engineered Paving Mat

Nonwoven Pavement Interlayer

ProductAs the Midwest’s “certified installer and distributor” of Owens Corning’s TruPave® Engineered Paving Mat, Road Fabrics, Inc. is committed to providing innovative and emerging technologies used to extend the service life of asphalt pavement overlays. TruPave® has been specifically designed to provide high modulus tensile strength while creating a moisture barrier to retard the effects of reflective cracking that accelerate the deterioration of the new asphalt pavement overlay. TruPave® is a hybrid fiberglass and polyester paving mat, that when saturated in asphalt cement, forms a monolithic water barrier to limit water intrusion in the pavement. In addition, TruPave® has high tensile strength at low elongation (strain), that is, energy is absorbed and dispersed, mitigating the advent of reflective cracking. TruPave®’s unique, nonwoven, randomly dispersed fiberglass construction process, gives your pavement 360 degree tensile reinforcement. Because pavements crack in all directions, the forces that cause cracking can be curtailed with the addition of TruPave® in your pavement overlay application.

The Difference TruPave® Engineered Paving Mat Makes:• Millable and recyclable: TruPave® will breakdown under

milling operations due to the unique use of fiberglass and polyester fibers; it is perfect for use in recycled asphalt paving mixes for sustainability and reducing the carbon footprint of producing virgin asphalt mixes and conventional pavement removal techniques.

• Improves fatigue resistance in flexible pavements: Laboratory testing proves that TruPave®’s high tensile strength improves flexural pavement performance under loading.

• TruPave®’s unique nonwoven fiber matrix construction provides for a multi-directional, 360 degree stress relief interlayer. As pavements exhibit cracking in all directions, TruPave’s® tensile strength and low elongation attributes are translated to the pavement section, mitigating further crack development in all directions.

• Helps to reduce the long-term maintenance and rehabilitation costs associated with pavements.

• Withstands the higher temperatures of today’s hot mix asphalt paving mixes.

ApplicationsTruPave® is specifically designed to be used in hot mix overlay applications over existing asphalt and/or concrete pavement, or in new construction between the asphalt layers. It is recommended to followOwens Corning’s Installation Guidelines.

TruPave® Engineered Paving Mat is ideal for: • Highways• Urban Streets• Airports• Bridge Decks• Parking Lots• Shopping Centers

ProcessTruPave® Engineered Paving Mat is manufactured using a wet-formed process, comprised of fiberglass and polyester fibers blended in an aqueous latex resin. This unique manufacturing process ensures that the fibers uniformly disperse and form a strong interlocking mat that will deliver tensile strength in all directions.

TruPave® is available in the following sizes:12’6” x 360’ (500 sy)10’0” x 360’ (400 sy) 6’25” x 360’ (250 sy)

Surface water runoff can com-promise the granular base by seeping through the cracks.

GlasPave prevents water frompenetrating the granular base.

GlasPave Paving MatImprove Pavement Life and Lower Overall Costs

Delay Reflective CrackingThe high performance hybrid fiberglass structure of the GlasPave® Paving Mats provides significantly greater tensile strength at low strain compared to conventional paving fabrics and other paving mats. The higher strength at low strain helps extend pavement life by delaying reflective cracking, which is a common contributor to costly repairs and the eventual failure of asphalt overlay applications.

Effective Moisture BarrierThe matrix structure of GlasPave Paving Mats allows the asphalt binder to fully penetrate and fill voids within the mat, limiting moisture infiltration into the pavement structure. Preventing water ingress into the lower layers of a pavement structure is critical to preserve the integrity and long-term performance of the pavement section. Even in the harshest environments, GlasPave Paving Mats will provide significant improvement to the service life of the road.

Thermal Stability Means No ShrinkageDue to the high temperature fiberglass matrix, GlasPave Paving Mats will not shrink or change dimensions when hot mix asphalt comes into contact with them as is common with polypropylene fabrics. This feature eliminates the risk of premature slippage or loss of bond.

More Robust than Conventional Paving FabricsThe additional stiffness of GlasPave Paving Mats, compared to paving fabrics and other paving mats, makes them more durable and less prone to on-site installation damage.

Trouble-Free Recycling on Future Rehabilitation ProjectsThe stiff fiberglass allows for easy, trouble-free milling for asphalt rehabilitation. Milled fibers are easily disbursed in asphalt millings and will therefore not negatively impact the recycling of asphalt for future projects. Recent testing at National Center for Asphalt Technology (NCAT) demonstrated that an asphalt mix containing 30% recycled asphalt pavement (RAP) with GlasPave fibers performed as well as RAP without GlasPave fibers.

Performance You Can Count OnGlasPave Paving Mats are manufactured by Saint Gobain ADFORS, the world leader in engineered grids and fabrics for the paving marketplace. A hybrid geosynthetic paving material, GlasPave® Paving Mats are a unique combination of fiberglass mesh embedded into high performance polyester mats. The result is the fastest growing engineered paving mats that deliver the highest tensile strength on the market when compared to any other paving mat or paving fabric. The distinctive design allows for a quick and strong bond with a variety of tack coats.

GlasGrid Pavement Reinforcement System

Today’s Most Advanced Pavement Rehabilitation System

Fatigue and reflective cracking in pavements is typically caused by traffic loading, age hardening or temperature cycling. When cracking is present, the traditional remedy has been to apply thicker asphalt overlays. For each inch of applied overlay, existing reflective cracks are generally deterred from reaching the surface for a period of one year.

The GlasGrid® System Extends Pavement Life By Up to 200%The GlasGrid® Pavement Reinforcement System provides additional support to resist the migration of reflective cracks in roadway applications. Manufactured by Saint-Gobain Technical Fabrics in Albion, New York, this interlayer system is composed of a series of fiberglassstrands coated with an elastomeric polymer and formed into a grid structure. Each strand has a remarkably high tensile strength and high modulus of elasticity; this is particularly important as asphalt concrete typically cracks at low strains. This combination makes the GlasGrid® System stronger than steel, pound for pound.

When the GlasGrid® System is “sandwiched” between the leveling and surface course asphalt in a conventional asphalt overlay, it becomes the hidden strength in the road – designed to turn vertical crack stresses horizontally and effectively dissipate them.

Easily Installed and Up to the Task

The GlasGrid® System is easily installed without specialized equipment or labor. With its pressure-activated adhesive, it’s considered to be the most expedient interlayer system relative to installation time. The GlasGrid® System has proven to be effective in every geographical area and climate – from desert environments to near-arctic conditions.

How the GlasGrid® System Reinforces a PavementWhen conventional rehabilitation procedures are used, an asphalt overlay is placed over the existing rigid or flexible pavement. This provides some additional road life, but the existing reflective cracks continue to propagate prematurely toward the surface, as shown in Figure 1.

When used to reinforce asphalt concrete, the GlasGrid® System helps to create a composite material combining the compressive strength of the asphalt mix with the tensile strength of glass fibers. By introducing a stiff tensile element at the base of an overlay, cracks propagating toward the surface are intercepted and prevented from immediately migrating further. Instead, the crack is redirected horizontally, as shown in Figure 2.

This process works best when “through-hole bonding” takes place between the asphalt layers. As the term suggests, this involves the development of a strong bond between the overlay and the underlying level-up asphalt layer. This can be achieved only when an open aperturegrid structure is used for reinforcement. The GlasGrid® reinforced overlay will itself start to crack in time, but at a much reduced rate, thereby significantly extending the life of the road.

Figure 1 Cracks migrate toward surface in unreinforced overlay.

Figure 2 Cracks are redirected in GlasGrid reinforced overlay.


GlasGrid System’s Performance Exceeds Other Interlayers

Engineers today can choose from several interlayer systems. These systems are made from various asphalt binders in combination with sand and/or aggregate, or from one or more geosynthetics, which may also becombined with binders.

Bituminous-based interlayer systems such as slurries and seals provide effective waterproofing but even with the advancement in modified binders, they offer limited crack mitigation benefits. Over the last 30 years, geosynthetic interlayers have proven to be worthy alternatives withtheir added stiffness, uniform quality and widespread availability.

A number of criteria can be used to determine the suitability of a specific interlayer product. Researchers have found that the performance of ageosynthetic interlayer system can be predicted based on the key material properties structure and strength.

StructureThe interlayer system is defined as being either open (GlasGrid System and steel mesh systems) or closed (composite grids and paving fabrics). An open grid structure promotes “through-hole bonding” and more efficient stress transfer to the grid by both the overlying and underlying aggregate matrices of the asphalt layers. This is particularly important to prevent the propagation of active cracks within the pavement. By contrast, the transfer of crack stresses in fabric-based interlayer systems takes place through the relatively weak bond formed between the asphalt binder and the fabric.

StrengthOnly GlasGrid Mesh and steel mesh systems have sufficient tensile strength at strains less than 3% to deter the propagation of cracks caused by traffic loading or thermal movement.

CreepLong-term creep strength is required to restrain the propagation of cracks associated with thermal movement or lane widening. The GlasGrid System and steel mesh are the only grids that possess sufficient creep characteristics to resist a high level of sustained stress over long periods of time.

Ease of InstallationWith its pressure-activated adhesive, the GlasGrid System is the fastest installed interlayer on the market. As much as 25,000 square yards of grid can be installed in one day using a standard laydown unit. In addition, the installation of the GlasGrid System can be easily adapted to local weather conditions or unique construction requirements.

Millability and RecyclabilityIn contrast with other interlayer systems, the GlasGrid® System is easily broken up by traditional milling equipment. It also has an additional benefit: its main component is silica, a natural substance that isenvironmentally friendly.

With the exception of steel grids in thin asphalt overlays, most geosynthetic interlayer systems are millable using conventional reclaiming equipment. However, when it comes to recycling reinforced asphalt, only pavements reinforced with the GlasGrid System can typically be ground up and reused in other road projects as a recycled asphalt pavement, or RAP.

Proven Performance Although advancements have been made to the coating and adhesive, the GlasGrid System is still manufactured as it was originally more than 20 years ago. This is testament to the product’s extensive and proven success on project sites throughout the world.

The Problem: Most government agencies know there is a need for longitudinal joint improvement. The longitudinal joint crack forms because the first paving pass creates an unconfined edge. Rollers can’t compact the edge to the same density as the interior of the mat. Then air and water intrudes into the HMA at the construction joint and damages the pavement over time. This causes premature construction joint failure and triggers maintenance or reconstruction long before the road should.

The Solution: J-Band, a Void Reducing Asphalt Membrane (VRAM), is placed under the intended area for an overlay construction joint, either 12” or 18” wide and with thickness up to 5/32”. J-Band is a hot applied asphalt membrane used to extend the life of longitudinal HMA joints. J-Band is resistant to flow and non-tracking to construction traffic within 30 minutes of application under the intended construction joint. J-Band migrates 50-75% into the HMA void structure after rolling, thus reducing permeability at the joint. The reduction in permeability minimizes water and air intrusion into the joint resulting in reduced cracking and stripping and improved pavement performance.

J-Band Void Reducing Asphalt Membrane Features:• Non-tracking within 30 minutes• 50-75% upward migration• Minimal joint cracking• Reduced joint permeability• Extended joint life

FiberMat

A truly innovative solution that delivers superior crack preventionCracking is a distress that will ultimately plague nearly every road or pavement surface. Cracks develop for a variety of reasons; among the most common are thermal stresses, fatigue, or reflective cracking from underlying pavement conditions. Whatever the cause, cracking continues to be one of the major problems affecting our pavements today. FiberMat®, one of the latest innovations from Colas Solutions™ and the family of Colas Companies, provides an economical, cost effective technique for treating and preventing the recurrence of pavement cracking.

FiberMat® is a specially formulated, polymer modified, crack resistant membrane that produces superior strength and flexibility. It forms a high tensile matrix upon application with a highly modified asphalt emulsion residue that is reinforced with engineered fiberglass strands. The FiberMat® system is installed by a specially developed machine that uniformly applies the fiberglass strands in a continuous application. The strands are sandwiched between two layers of modified emulsion prior to application of an aggregate cover. The final product is then rolled to seat the aggregate into the surface. This combination of highly modified asphalt residue and a fiberglass reinforcement matrix creates a powerful resistant membrane interlayer that absorbs stresses in the pavement structure and delays the onset of cracking. Unlike conventional geotextile reinforced interlayers, FiberMat® is easily recycled without any issues, is easily constructed, and saves time and labor on application for the user without the usual wrinkles, rips and tears associated with fabrics.

A superior fiber reinforced crack inhibiting system provided in two unique formats

FiberMat® can be utilized to address two distinct distress application needs: Type A is applied as an ultimate wearing surface for stand alone surface treatment applications. Type B is a Stress Absorbing Membrane Interlayer (SAMI) for interlayer applications used to reduce cracking in pavement system overlays.

• When used as a surface treatment, FiberMat® Type A performs as an enhanced crack-resistant high performance resurfacing treatment.

• When used as a SAMI, FiberMat® Type B can be overlaid with a variety of surfacing treatments, including micro-surfacing, slurry seals, Warm Mix Asphalts, Hot Mix Asphalts, and Ultrathin bonded wearing courses such as DuraThin™, NovaChip® etc.

Whichever application is more suited for your problem area, you can be sure that FiberMat® will provide a strong, waterproof membrane that absorbs pavement stress and resists cracking, reflected or generated in the pavement. Its superior tensile properties provide enhanced resistance against the recurrence of reflective cracking, a superior improvement over conventional SAMI treatments.


FiberMat inhibits cracks from below the surface

Today’s road professionals face many challengesToday’s roads are faced with higher traffic counts, heavier loads, and a more demanding public while buyers and user agencies are faced with dwindling budgets and the need to do more with less.

Self-adhesive membranes are used to retard reflective cracking by surface waterproofing cracks and expansion joints on Portland cement, concrete potholes, and cracked asphalt surfaces. Narrow widths are used to cover existing joints and random cracks.

Self adhesive membrane is comprised of rubberized asphalt waterproofing element and a non-woven pavement reinforcing grade polypropylene fabric laminated to the outer surface. It is approximately 65 mils thick. It is wound on a disposable treated strip sheet to prevent blocking in the rolls.

Following are the advantages of self-adhesive membrane for highway waterproofing:

1. It prevents surface water entering old cracks in the substrate thus slowing base failure and reducing reflective cracking.

2. It permits following work to proceed immediately after application of membrane.

3. It has elastomeric properties to accommodate normal expansion and contraction of the substrate.

4. It is easily applied due to the plastic release film

PavePrep and PavePrep SAStress Relieving Interlayer

PavePrep is a highly effective stress relief interlayer material consisting of a high-density mastic, woven polyester fabric and a coated quick release liner. Installed in strips over cracked, spalled concrete or asphalt, PavePrep intercepts and reduces the stresses induced by thermal expansion and contraction, thereby reducing the tendency for cracks to reflect through the overlay. PavePrep also prevents moisture interpenetration that contributes to further structural decay ofthe surface and underlying pavement. PavePrep extends the overlay service life and reduces maintenance costs.

PerformancePavePrep is a high-density mastic, laminated for extra strength and flexibility.This tough synthetic combination is capable of surviving the rigors of installation and loads encountered on highways and airports. PavePrep retains its thickness after application, even when directly exposed to vehicular traffic. PavePrep performance is optimized on road surfaces that do not exhibit structural deficiencies or drainage problems. As such, these problems should be corrected prior to the application of PavePrep.

InstallationFast, economical, and requiring no special equipment, PavePrep is unrolledat the jobsite and applied. It can be used on milled and unmilled surfacesafter the application of an AC tackcoat. PavePrep SA, with a peel-and-stick adhesive on one side, is also available. On most surfaces, PavePrep SA does not require a tackcoat. Before applying PavePrep, users should carefully read the Application Procedures.
