| Bitumen Concrete Reinforced
Fiber-Polyester Fiber
After
the po1ypropylene fiber successfully used into the
cement concrete ,polyester fiber is a new-developed
engineering material in recent years.With polyester
as its raw material, the fiber is produced through
adding some functional additive ,
by
plastic melting,extruding,high-ratio stretching
and special surface disposal.And shaped by cutting
with special machine Its appearance is beam-like structure
with many monofilament fiber collecting.
Besides the small thinness,high tensile
strength and easily scattering,polyester has good
heat-resistance.It can be used in hot-mixing bitumen
concrete projects and reinforced crack-resistance
for high-tensile concrete,so it is an ideal multi-functional
reinforced material.
According to the testing report by
many authorized organizations,the polyester fiber's
main technological performance indexes all reach the
advanced level of the same products in the world.
