Product Detail
Product Introduction
High permeability emulsified asphalt is mainly used for road surface layer oil cloth, which can fully penetrate the small pores in the semi rigid base layer, block the connecting holes in the base layer material, and prevent water from entering the interior of the base layer. The fully permeable layer oil can bond and fix the loose aggregate on the surface of the base layer, improving the bonding between the semi rigid base layer and the asphalt surface layer.
Product Features
Reduce the surface tension between asphalt and inorganic base materials, ensuring that emulsified asphalt can penetrate deeper than 5mm along the small pores in the base layer, fully meeting the requirements of the permeable oil industry indicators, and achieving a true permeable effect.
