Asphalt mixes

For thousands of years asphalt mixes have been regarded as inexpensive, innovative building materials.

Each of the constituents—stone, sand and bitumen—is environmentally friendly, both by itself and when bonded in the asphalt mix. For example, bitumen can be used to waterproof drinking-water reservoirs. Today, asphalt mixes replace tar, which has been banned since 1965 owing to its environmental incompatibility. Furthermore, asphalt is a universal material that adapts perfectly to the respective local conditions. Whether for bridges, roads or drinking-water reservoirs, cycle tracks or motorways, tropical or arctic weather, asphalt mixes are at home everywhere.
