INTRODUCTION:As the transportation
infrastructure of our country is being constructed extensively, especially the
rapid development of the freeway construction, the asphalt pavement is playing
more and more important role now. With the channelization of the transportation,
the increase of the traffic volume and the load of the transit, etc, there is
higher requirement to the quality and durability of the advanced asphalt
pavement. To avoid the influence to the lifetime of the general asphalt
pavement caused by its early damage, such as crack and potholes of the track,
recent years, that the industrialized polymer synthesis fibers are used in the
asphalt concrete as the reinforcing material, has got the popular concern and
wide recognition from the transportation and highway research department of the
world. PET-Fiber is a new kind of reinforcing and crack-resistant material for
the asphalt concrete. It is a kind of bunchy monofilament synthetic fiber and
manufactured by special technique with 100% PET. It has the advantages of
anti-high temperature, anticorrosion, high strength, high chemical stability,
high gripping force with the asphaltum, etc. When put them into the asphalt
concrete ,after mixed ,they can form a lot of monofilament stereo distribution
,that could reinforce and bridge the asphalt concrete, uprate their mechanical
property, and prevent the crack. The Physicochemical Properties of PET-Fiber.
Specifications:
Diameter:from 10um to 15um

THE MAIN APPLICATION OF PET-FIBER:
The newly-built road surface of asphalt concrete
The old pavement overlay of asphalt concrete(black+black)
The old pavement overlay of cement concrete(white+black)
The defect mend, cold patch, joint grouting of the roads
Pave the asphalt surface on the steel construction bridges
The waterproof of the bridge surface
