A textile material (10) comprises a base web (11) having united therewith an overlying fibrous layer (12) which can be filled with particulate material such as sand. The base web (11) has on its underside an enhanced friction layer which can be created by needling tufts (13) of said fibrous layer through the web (11). A composite material consisting of said textile material (10) and a filling of sand is useful as a component of a road structure overlying a substrate (14) and supporting an overlying layer (15) of fragmentary material such as stone which in turn supports a road surface layer 16. <IMAGE> |
