Abstract:  
A method of treatment of a surface over which vehicles travel with particulate material is disclosed. Particulate material is projected onto the surface with kinetic energy exceeding the bonding energy of the surface or the bonding energy of a deposit adhering to the surface which it is desired to remove. In the former case the method effects texturing of the vehicular surface by pitting thereof. In the latter case the method effects cleaning of he surface by removing the bonded deposits therefrom. Additionally, the method can be used for preparing a surface for repaving or for removing ice therefrom.
