Cracking posted principle:
Mechanical effects: polymer material as a stress-absorbing membrane, can increase the likelihood of vertical cracks along the interface within the grassroots level in the horizontal direction of development, thus delaying the time the road crack reflection table.
Bridging role: After entering the asphalt concrete pavement cracks, geosynthetics and linking high-temperature cracking section of fabric to make a double bridge has a certain tensile strength, reducing deformation crack open, reducing tensile stress concentration at the crack tip.
Interlocking snap action: improving cross-section shear cracking load transfer capability. Pitch-based polymer material has a certain low temperature, the material is maintained at a low temperature can not change shape, and has good waterproof effect, prevent the road surface cracking water infiltration.
