Surface dressings are thin layers which are produced by spraying a bonding agent on the substrate and spreading chippings on top. With RapsAsphalt it is possible for the first time to use domestic, re-growing raw materials in road construction bonding agents.
The surface properties of the finished layer provide a great variety of advantages:
- Sealing effect
- Favorable glare ice behavior
- Good grip
- Good sight at night
- Suppressed glare in wet weather
- Easier winter service
- Regenerative effect
- Low production costs and quick installation
- Long service life and recyclability
Depending on the number of work steps, we distinguish between different types of surface treatments:
Simple surface treatment (EO 4/8):
Simple surface treatment with double application of chippings (EOSD 8/11 + 2/4):
Simple surface treatment with double application of chippings in sandwich design (EOSD 8/11 + 2/4 "Sandwich"):
Double surface with vertical grain on unbound supporting layer (Makadam) - "penetration cover":
