High performance, pervious and sound-absorbing concrete ideal for permeable pavements.

DrainBeton® is a special high-performance pervious concrete specially designed for use in the permeable road construction sector.

DrainBeton® can be used as a single layer (either concrete-grey or coloured) or covered with an open graded asphalt wearing course to create a dual pervious and sound-absorbing pavement.

DrainBeton® is the only Italian patented pervious concrete for road

applications.

The workability of the mix allows it to also be laid using a slipform paver.

STRENGTHIn about 5-7 days after laying, DrainBeton® reaches compressive strength levels sufficient to open the road to vehicular traffic. The high levels of strength of DrainBeton® make it suitable also for road surfaces with high volumes of traffic.

The advantages of using DrainBeton®

SURFACE DRAINAGEIts high percentage of interconnected voids allows DrainBeton® to drain rainstorms, while still guaranteeing high load resistance values.

DE-ICING EFFECTThe open matrix of DrainBeton® allows air to circulate continuously, which accelerates the thawing process of snow and ice, and thus reduces the need for ploughing or clearing during winter. The presence of interconnected voids also allows any stagnating water to expand freely while it freezes.

REDUCTION OF THE “HEAT ISLAND” EFFECTThe light colour of the material and the high porosity of the mix lead to lower heat absorption compareds bituminous concrete, thus guaranteeing moderate temperatures for surfaces that are exposed to the sun. These characteristics of DrainBeton® enhance faster heat dissipation and a reduction of the heat island effect.

GROUNDWATER MITIGATIONIts excellent draining capacity make DrainBeton® particularly suitable for applications in protected areas, where rainwater must be allowed to pierce the soil. The material does not release polluting substances into the water as it drains through, and as its structure acts as a filter, there is less need for rainwater harvesting, thus reducing the harmful effects of potential contaminants.

RESISTANCE TO FIRE AND HYDROCARBONSDrainBeton® is fire and hydrocarbon resistant. This allows it to be used in areas with a high risk of fire (e.g. car parks, petrol stations, fuel storage areas, etc.).

MINIMAL MAINTENANCEThe physical, mechanical and aesthetic characteristics of DrainBeton® remain unaltered over time, and it does not require any particular maintenance. In areas subjected to large quantities of detritus or dust, its draining capacity can be restored by cleaning it with high-pressure water or by using a street sweeper.

ENVIRONMENT-FRIENDLY COLD LAYINGLaying DrainBeton® is an environment-friendly operation as it is carried out “cold”, so with no emission of fumes, no risk to the safety of the operators, and a significant saving in energy requirements.

Colours

DrainBeton® can be used in its natural colour or with the addition of different colour pigments. This makes it ideal for use in all applications where perfect blending with the environment is required such as parks, natural landscapes, protected areas or historic city centres, but also to create road surfaces with integrated signage with no risk of contaminating the environment as the colour is added to the material by adding pigments to the mix, with a natural colour effect.

DrainBeton® surfaces can also be coloured with special non-film-forming mineralising solutions in many colours. By penetrating into the natural-coloured surface, they make the material more resistant to aggressive agents (de-icing salts, detergents, tangential mechanical action, UV rays), creating a perfectly uniform colour that is extremely durable, and does not affect draining capacity.

Laying

DrainBeton® can meet construction site requirements, reducing laying times and costs.

The mix was expressly designed to be laid by a slipform paver or manually using lightweight tools.

Applications:

• Self-draining road courses (in a single layer or combined with an open graded asphalt wearing course)

• Cycle lanes and pedestrian paths• Service and access roads• Mixed-use areas and “30 km/h

zones”• Lanes and trails in protected

areas• Sport tracks and golf paths• Parking lots• Water management systems and

retention basins

Laying using a SLIPFORM PAVER

The workability of the concrete enables it to be laid using the same methods and machinery as normally used for road paving. Laying using a slipform paver is in all points similar to laying asphalt, but at room temperature, and with no fume emissions into the atmosphere. DrainBeton® is compacted directly by the paver’s screed and additional rolling is not required.This makes laying faster, and also gives full control over the thickness and smoothness of the surface.

ADVANTAGES during laying

• The cement is laid cold, so there are no emission of fumes and no risk to the safety of the operators.

• The concrete can be laid at room temperatures much lower than those recommended for bituminous mixes.

• It requires a subgrade with the same regularity and load-bearing characteristics as normally needed for road construction.

Manual layingDrainBeton® can be laid manually by using light weigth tools (vibration smoothing, roller screed, etc.).

Dual permeable sound-absorbing road pavement

DrainBeton® can be used in combination with an open graded asphalt wearing course to provide a dual permeable and sound-absorbing road pavement.

DrainBeton® can therefore replace the base course and binder (which are normally impermeable), giving the package not only both permeability and sound-absorption qualities, but also lower deformability and greater load resistance, thus prolonging the surface life of the pavement.

The advantages of the double layer configuration

• Thanks to the asphalt wearing course, the permeable road pavement looks “normal”, and as such is both well-received by both Public Authorities and road users.

• Also thanks to the asphalt wearing course, surface grip, smoothness and compatibility with road markings are guaranteed.

• The presence of two highly porous layers gives the paving a high self-draining capacity as well as sound absorbing properties at different sound frequency levels.

• Thanks to the load-bearing capacity and fatigue strength of the concrete, the paving has a long service life with minimum maintenance, and this affecting principally the asphalt wearing course.

• The double permeable layer with its self-cleaning action reduces blockages in the interconnecting voids to a minimum, thus prolonging the self-draining properties of the material over time.

• The construction and maintenance costs are lower than those of a traditional road package.

Lower defomability and greater load resistance.
