Product Description

TB-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 **0% PET. It has the advantages of anti-high temperature, anti-corrosion, 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 Function of the TB-PET-Fiber 1）Improve the stability of asphalt concrete in high temperature That the 3D stereo distribution of TB-Fiber monofilament , its super adsorbability as well as no twist with the asphaltum, strengthen the cohesion and stickiness of the asphalt concrete；furthermore, the reinforcement and bridging function of the crossbinding fiber monofilament, decrease the liquidity of the asphaltum and increase the stability of the asphalt concrete in high temperature. 2）Improve the anti-crack of asphalt concrete in low temperature Generally, in the condition of low temperature and the sudden fall of the temperature (***** winter in north), the asphalt roads will shrink or crack as a result of the stress relaxation. Put TB-PET-Fiber into the asphalt concrete, because there are a lot of crossbinding fiber monofilaments in the concrete , the elasticity of the asphalt concrete is improved , which makes it can resist the deformation effectively, maintain high flexibility and anti-stretch strength, resist the shrinkage effectively, reduce the crack, consequently improve the anti-crack of asphalt concrete in low temperature 3）Improve the anti-fatigability of asphalt concrete The reinforcement of TB-Fiber in the concrete increases the developing modulus of elasticity by 1.**1.4 times and improves its fatigability
