Product introduction:
“Tian Yi ”polyester fiber is a 100% modified polyester fiber product specially used for asphalt concrete reinforcement. Been subject to UV-proof treatment, this fiber has a high aging resistance and thus can improve the cohesiveness, high temperature stability and fatigue durability of asphalt pavement. It also has a good resistance for low-temperature cracking and reflective cracking. The surface-treated fiber can evenly disperse in asphalt concrete, forming strong bonds with asphalt concrete to serve as an effective reinforcement bar. The fiber has been widely used in all kinds of asphalt concrete pavement such as bridge deck pavement, road pavement and toll station pavement.
