asphalting Austria

...Underlay of access roads with gravel (our partners handle asphalting, etc.) For a surface like asphalt on an access road or the paving in front of a garage to remain level and attractive for many years, the subsoil must meet certain requirements. On one hand, it must be stable enough to prevent depressions caused by the weight of vehicles. On the other hand, water permeability is crucial; otherwise, during winter frost temperatures, heaving can occur, leading to cracks in the asphalt.
