FiberMat®

FiberMat® is an innovative, crack-inhibiting and sealing membrane. A combination of polymer-modified asphalt emulsion, chopped strands of fiber glass, and aggregate incorporate to create a robust membrane.

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.

FiberMat® has two different forms, known as Type A and Type B. Type A is referred to as an Enhanced Chip Seal whereas Type B is known as SAMI (Stress Absorbing Membrane Interlayer).

Type A | Enhanced Chip Seal

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.

Type B | Stress Absorbing Membrane Interlayer (SAMI)

Type B follows a similar pattern as Type A. The glass fibers are dispersed at a rate of 3 to 4 ounces per square yard, dependent on the severity of the cracking. The emulsion is again applied in two simultaneous applications totaling 0.3 to 0.5 gallons per square yard. As with Type A, an application of aggregate is applied, allowing the surface to be opened to traffic. These layers create the strengthening membrane interlayer. From there, an additional overlay surface is applied. This increases the lifespan and durability of the pavement, while giving the owner their desired final road surface.
