Mastic asphalt has a structure that is almost completely cavity-free, making it a highly versatile material. Due to its extreme robustness and resistance to salt water, it can be used as a surface for roads and footpaths as well as for mining and bridge construction. Mastic asphalt separates dry matter from wet matter, thus protecting the structure of the surface. This makes it an ideal material for sealing and wearing surfaces, as well as for protective and surface layers in civil engineering.
