Single Pass Cold In-PlaceAsphalt Recycling

Today and Tomorrow's Alternative in Pavement ReconstructionWith fewer funds available for public

works construction, municipalitiesmust spend taxpayer dollars wisely.Also, budget constraints in the privatesector require prudent and innovativemaintenance programs.

One solution is Single Pass ColdIn-Place Asphalt Recycling utilizingthe Wirtgen 2100 OCR cold recyclingmachine.

The Wirtgen 2100 OCR featuresa variable width vibrating screed, amilling drum equipped with automaticgrade control and a liquid emulsion

Introducing the liquid emulsion additivefrom the asphalt distributor to the cold

recycled pavement in a single pass.

The finished product prior to compactionby vibratory equipment. Notice the mat

produced by the vibratory screed.

This 2100 also utilizes all-tracksteering, allowing it to easily navigateparking lots, cui-de-sacs and otherareas where maximum maneuverabilityis required.

This operation creates a bituminousbase at a specified depth without clos-ing the road. This allows the motoringpublic complete access to the road,including city and safety services.

Specialized Construction's crewsare known for performing top-qualitywork and are backed by a fleet ofmodern, state-of-the-art equipment,which helps us deliver on-scheduleperformance, and on-time completionof our projects.additive metering system. This system has

an electric control unit with a programmablemicroprocessor that compensates for theforward speed of the machine, the millingdepth and material density.

These components work together toproduce a recycled pavement with thespecified gradation and liquid content ina single pass, completing the rehabilitationof the roadway faster. An example of road reconstruction with

the Wirtgen 2100 OCR utilizing thesingle pass method.

The pavement surface is recycled to a specific gradation, liquid emulsion additive intro-duced to the grindings, and the material augered through a vibrating compaction screed.Advantages include superior gradation of material, immediate compaction of the recycledpavement, less disruption of traffic flow in that the roadway is never closed. .

The Wirtgen 2100 OCR features a variable width vibrating screed, milling drum with auto-matic grade control, and a liquid emulsion additive metering system which compensatesfor the forward speed of the machine. These components work to produce a Cold In-Place Recycled Pavement, which is truly state of the art.

Other benefits of theWirtgen 2100 OCR andSingle Pass Recycling

.:. 100 percent recovery of the oldroadway material investment

.:. A project cost savings of between 25and 40 percent, when compared totraditional road surface rehabilitation.

.:. Conversion of the old roadway intoa base material with a much higherstructural value, offering addedprotection of your new investment.

.:. Elimination of cracking pattern in theold pavement surface .

•:. Immediate use of recycled roadwaywith less inconvenience for motoristsand shorter disruption of trafficpatterns.
