DENSIPHALT

Description Densiphalt®

is a semi-flexible joint-free topping, well suited for use in heavily trafficked areas, and where flexibility, durability and wear resistance are high priorities. Densiphalt® consists of an opengraded asphalt, with the voids filled with a high-strength cement-based mortar. Densiphalt® is applied as a 30-100 mm layer, and is laid on an adequate base course such as asphalt, lean-mix concrete or standard concrete. Densiphalt® can be coloured in a variety of shades.
Specification

The base course is sealed with bitumen emulsion. The open-graded asphalt is laid (special recipe). The dry Densiphalt® mortar is mixed with water in a special continuous flow mixer or batch mixer. The open-graded asphalt is filled with Densiphalt® mortar. The surface is finished with a rubber scraper. Finally, the surface is sealed with AQUASEAL or by sand saturation.
