Polyester engineering fiber is a new-developed engineering material in recent years with 100% polyester. The fiber is a bundle of synthetic fiber which produced by a unique technique. It is characterized by high tenacity, corrosion resistance, high temperature resistance, high chemical stability,high grip of bitumen. When added to bitumen and concrete, it will form three-dimensional distribution with enormous quantity of fiber, the purpose of which is to reinforce and connect. It can improve the mechanical properties of bituminous concrete, and prevent it from cracking.   

Specification:

PS:

Tenacity, diameter and length of the fiber are various according to customers demand.

Main function:

·Improve the high temperature stability of bituminous concrete.

·Improve the low temperature cracking resistance.
·Improve the fatigue resistance.

·Efficiently improve the crush resistance ,tensile property,shear strength and impact strength.

·Improve the water stability and anti-stripping property of bituminous concrete, thus enhancing road quality and increasing the service life.

Application:

·New built bitumen road;              ·Recovery of old bitumen road layer;
·Repair of old cement road layer;      ·Defect maintenance of road surface;
·Reinforced crack-resistance of fine aggregate high-tensile concrete project
