one 1. Characteristics of the construction method

1.1 Kerosene diluted asphalt permeable layer is more expensive than emulsified asphalt permeable layer, but it has a good penetration effect on inorganic binder base layer and semi-rigid base layer.

1.2 By spraying kerosene to dilute the asphalt prime coat, the prime coat oil can penetrate deeper into the surface pores of the base layer, enhancing the connection between the base layer and the surface layer. It plays a stabilizing and consolidating role on the surface of the base layer.

1.3 Ensure the penetration depth of the primer oil to maintain a good connection between the base layer and the primer layer.

2 Scope of Application

The prime coat construction applied to inorganic binder base and semi-rigid base of asphalt pavement is suitable for the asphalt pavement construction of high-grade highways across the country.

3 Process Principle

Kerosene diluted asphalt prime coat, with a fineness at the molecular level, can achieve ideal penetration on the surface of any non-asphalt base material when the viscosity is appropriate. The sprayed primer oil should penetrate down, leaving no oil film on the top surface of the base layer. The primer only has a penetration depth but no independent thickness. Kerosene diluted asphalt prime coat penetrates deeply into the base layer. Timely application can effectively retain moisture in the base layer, which is conducive to maintaining the surface strength of the base layer and preventing it from loosening easily.
