Abstract (en)

[origin: EP0127470A2] A method for applying a skid-resistant surface layer to roads involves the application of a layer of chippings which is then covered by a layer of bituminised sand. This sand fills the voids between the chippings such that, during subsequent compression with a roller, the chippings cannot rotate and remain in a random orientation. The resulting surface layer contains a relatively large proportion of chippings having a sharp or pointed edge uppermost and thus possesses good skid-resistance properties. The method may be adapted either for use in the resurfacing of an existing road or for applying a skid-resistant surface during the construction of a new road.
