The crack paste use good performance, high ten- sile strength, can enhance the substrate fiber materials of permanent anticorrosion, covering high perfor- mance viscoelastic materials through special process- ing on the ratio. Crack paste is a polymer and bitumen based high strength tensile base, high temperature

and high strength asphalt compatible fabric composites. This product has self-adhesive, construction is convenient, direct and stickup cracks. This structure will now on the highway to prevent crack several measures of organic synthesis application, is up- grade products for white change black highway on waterproof and anti crack.
