Pavement is an important part of transportation, and the quality of pavement directly affects the safety and comfort of traffic. As an important part of pavement structure, the lower seal coat has strong reinforcement and waterproof functions. This paper will discuss the magic of the lower seal coat in depth to help readers better understand the mystery of pavement structure.

Add a lower sealing layer to match the primer.

By adding the lower seal coat and cooperating with the prime coat, the surface layer and the base layer of the pavement can be perfectly combined, the continuity between layers can be enhanced, and the load transmission can be smoother.

Add waterproof armor to the road.

The sealing layer under the asphalt surface layer adds waterproof armor to the pavement, effectively preventing water infiltration and prolonging the service life of the pavement.

Enhance friction resistance and adhesion.

The magic of the lower seal coat is to enhance the adhesion of friction, so that the surface layer and the base layer can jointly resist the load, improve the overall strength of the pavement and ensure traffic safety.

Guard the grassroots and undertake temporary traffic.

The lower seal coat can not only protect the base, but also undertake temporary traffic, thus improving the pavement health and prolonging the service life of the pavement.
