FiberMat® Type A uses the patented FiberMat® process – a combination of special polymer modified asphalt emulsion, chopped fiberglass strands and aggregate. This robust mixture acts as a highly resilient waterproof membrane that effectively bridges alligator distressed pavements and also delays reflective cracking.
The process is superior to other surface treatments as there are no adhesion problems and the seal produced has greater tensile strength – by virtue of the glass fibers – that defies stresses placed upon it. The glass fiber mesh within the membrane provides superior embedment with the aggregate applied. The process itself is very fast to apply. It can be opened to traffic within 15 minutes after laying regardless of temperature or humidity thanks to an available controlled breaking system.
Why it Works:
Research has concluded that FiberMat® Type A has significant tensile strength and flexibility to absorb movements in the pavement structure and delay the pavement from cracking. The research also showed that the wheel track cracking rate improved by 300% due to the fiberglass delaying the top-down cracking. This membrane is proven to be effective in dissipating stresses and improving aggregate interlock with help of the fiberglass strands.
Application:
A specially developed unit chops glass fibers in-place and sandwiches them between two layers of asphalt emulsion prior to the application of a application of 1/4”, 3/8”, or 1/2" size aggregate, or combinations thereof, which is then rolled into the surface. The glass fibers are applied at a rate of nominally 2oz/ square yard, depending on the severity of the cracking. Prior to and following fiber distribution, polymer modified asphalt emulsion is applied in two simultaneous layers totaling 0.4-0.6 gal/ square yard.
