Fibermat’s® unique properties help absorb stresses generated in the pavement structure. This results in a flexible and waterproofing barrier.
In both types, a specialized and complex machine is used to precisely conduct the process. First, a layer of polymer modified asphalt emulsion is deposited onto the road surface. Then, strands of fiberglass are fed through the 40 onboard cutter assemblies and are sliced into a predetermined length and weight per square yard. A compressed air system ensures that these strands of fiberglass are enmeshed in the roadway. An additional layer of polymer modified asphalt emulsion is then applied overtop.
In Type A, fibers are applied at a rate of nominally 2-3 ounces per square yard, dependent on the severity of the cracking. The asphalt emulsion is applied in two simultaneous applications totaling 0.4 to 0.8 gallons per square yard. The final step is the application of aggregate. This creates a new surface similar to a rolled chip seal, but with increased resistance to cracking due to the inclusion of fiberglass.
