FiberMat Type A uses the patented FibreDec® 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 aggravated 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 that defies stresses placed upon it. 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 a 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 use of a chopped fiber-reinforced membrane was shown to enhance the performance of an overlay by 30% (fatigue and tensile stress) and wheel-track cracking rate by 300%.
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 dressing of 6mm, 9mm or 12.5mm (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 75 g/m2 (2oz/SY), depending on the severity of the cracking. Prior to and following fiber distribution, polymer modified asphalt emulsion is applied in two simultaneous streams totaling 1.8 - 2.7 l/m2 (0.4-0.6 gal/SY).
