Sand-containing fog seal is one of the fog seal technologies, and it is also a highway preventive maintenance technology.
The sandy fog seal layer is composed of asphalt, polymer modifier, fine aggregate and catalyst. It can penetrate into the joints of aggregates and flow into the pores, restoring adhesion and preventing water from seeping down the road surface. The fine aggregate sprayed at the same time also provides a good anti-slip effect.

Characteristics of sandy fog seal:
1. Anti-slip, filling, water sealing, etc. The sandy mist seal layer is mixed with a certain amount of fine sand, which can greatly improve the anti-skid performance of the road surface. At the same time, the asphalt sand mixture in the sand-containing fog seal layer has good fluidity. It can not only penetrate and fill micro-cracks or gaps in the road surface, but also fill and seal water.
2. Strengthen adhesion. Polymer modifiers are also materials in the sand-containing fog seal layer, which can delay the aging of pavement binder and maintain or strengthen the bonding performance between asphalt and aggregate.
3. Wear resistance: The usage ratio of the sandy fog seal is strictly in accordance with regulations. Therefore, a protective layer will be formed on the road surface after construction, which improves the wear resistance of the road and extends the service life of the road.
4. Beautify roads. Highway preventive technologies have their own unique proportions, as does the sandy fog seal. It can reduce the intrusion and influence of ultraviolet rays on the road surface, and has a long-lasting effect on improving the road surface and color.
5. Harmless and environmentally friendly. The technical parameters of the sand-containing fog seal are all proportioned in accordance with national regulations. During production and construction, no harmful volatile substances will be produced to the environment and human body. It is a very environmentally friendly asphalt technology.
The sandy fog seal is composed of a variety of materials, and combined with their respective characteristics, the current sandy fog seal is formed. For users with related needs, you can contact us!
