1, road anti-crack paste isolation function.

The anti-cracking paste (also called anti-cracking paste) is laid to isolate the cracked surface layer from the asphalt surface layer. The road anti-cracking paste avoids the direct contact between the cracked surface layer and the asphalt surface layer. The crack tensile stress of the base layer cannot be directly transmitted to the asphalt concrete surface layer. Although the bonding force between the base layer and the surface layer is reduced, the polymer anti-cracking paste can make the upper and lower layers well integrated and bear the vehicle load together, it is sufficient to prevent the relative displacement of the upper and lower layers of the interface and remain continuous.

 

2. Reinforcement function of road crack prevention paste.

Anti-cracking paste (also known as anti-cracking paste) has a certain strength and can withstand a certain crack tensile stress. When the crack tensile stress increases and is greater than the tensile strength of the anti-cracking paste, the anti-cracking paste begins to deform, and the surface layer begins to bear the tensile stress transmitted by the anti-cracking paste. The anti-cracking paste layer will bear all the tensile stress of the crack. Obviously, the anti-cracking paste plays a role of reinforcement. In this sense, it improves the tensile strength of the pavement structure layer.

 

3, road anti-crack paste energy dissipation buffer effect.

Anti-cracking paste (also known as anti-cracking paste) is a material with certain extensibility. The polymer has good low-temperature flexibility. It is laid on the asphalt pavement layer, which is equivalent to setting up an elastic layer. The tensile stress of the base crack extends to a wider range through the anti-cracking paste polymer, thus alleviating the stress strength at the crack. The elastic layer can absorb part of the tensile energy.

 

4, road anti-crack paste water seepage prevention function.

Anti-cracking paste (also known as anti-cracking paste) polymer can form a complete water impermeable layer, can cut off the pavement water to penetrate into the roadbed, so as to protect the strength of the base, so that the nature of the base material will not further deteriorate. The anti-cracking paste used in asphalt pavement layer can effectively inhibit the upward transmission of cracks, and play the anti-cracking effect and energy absorption effect of the anti-cracking paste in the actual project.
