Polymer anti-crack paste

Product Description

polymer crack stick is a kind of high quality road polymer modified material, with high tensile strength tire base and high temperature resistant fabric.

Principle

Mechanical effect: High-molecular polymer materials as a stress absorbing membrane, can increase the likelihood of vertical cracks of the grassroots level, which develops along the interface in the horizontal direction, thus delaying the time that the road crack reflectsto the road table.

Bridging role: After crack is into the asphalt concrete pavement, the double bridging function of geotechnical synthetic material and high temperature resistant fabric makes the cracking section has a certain tensile ability, reduce the deformation of the crack, and the stress concentration of crack tip.

Interlocking: Improve capacity of the shear load transfer resistance of the cracking section. The molecular material of asphalt base has a relatively low temperature, which makes the material don’t change it’s shape; And the good waterproof effect prevents from the infiltration of water for the cracking road table.

Advantage 

Polymer crack stick overcomes the interface caused by the crack for only using geotechnical cloth and glass fiber grill, and the interface influences the force condition of asphalt mat and the crack resistance; Polymer crack stick also overcomes the translation,fold in the paving process of geotechnical cloth and glass fiber grill, which influences upper and lower structure layer adhesion. The asphalt base stress absorbing membrane can only absorb stress, but can not resist to residual stress and disperse stress, polymer crack stick gives a good solution for this. This special structure can not only prevent from cracking, but also has a good effect for water infiltration, especially as for water infiltration after the road frosts crack, it has a good low temperature resistance.
