What is Reinforced Asphalt Fiber Additive?

This innovative product is made from para-aramid fibers (polymer fiber).  Aramid fibers are used in military applications for body armor fabric. When added to hot mix asphalt, the fiber extends pavement service life by dramatically improving the dynamic modulus of the asphalt layer (provides three-dimensional reinforcement) and increases the asphalt’s resistance to cracking and rutting. Furthermore, it reduces the amount of asphalt required, saving up-front costs on material. Long term, it helps extend intervals between routine maintenance. In essence, this is as close to ‘bulletproof asphalt’ as it gets.
