Anti-cracking paste is a roll-on crack-resistant waterproof diaphragm, which is made of 1.5mm or 2mm thick polymer waterproof membrane coated on anti-wrinkle and anti-heavy-duty polypropylene material, and compacted together by strict process.

 

Anti-crack paste with self-adhesive layer anti-crack, waterproof material. This structure is an organic combination of several anti-cracking and waterproof measures such as geosynthetics and stress absorbing layer materials used alone on the highway, and is an optimized combination of anti-cracking and waterproof materials between the current highway layers.

 

Anti-cracking paste is mainly used for highway, general highway and urban road pavement base of the new and maintenance projects. With high tensile strength, good toughness and surface viscosity, suitable for pavement base, can prevent cracks caused by temperature and vertical load reflection to the surface layer.

 

When laying hot asphalt mixture, the top high-strength and high-temperature resistant fabric will not deform at high temperature to ensure that a local high-strength asphalt mixture structural layer can be formed; the upper coating polymer seeps from the gap of the fabric after hot melting, and bonds with asphalt mixture very well; the lower coating has enough polymer to fill the potholes on the base surface after melting, thus enhancing the bonding force with the base surface, under the coating and the stability of the tire base to ensure the formation of a layer of relatively uniform thickness of the composite interlayer, play a crack resistance waterproof requirements.
