This Information Paper summarises a programme of research that included studies of the slip resistance of products in use, the wear and abrasion of materials, and the overall durability when subjected to vehicular and pedestrian traffic. The project concentrated on natural stone products but also included a comparison of similar products. The work was carried out between 1995 and 1997 so that the results were available to CEN/TC 178 Working Group 2 during the drafting of the European Standards for natural stone paving, setts and kerbs. This paper will be of interest to architects, specifiers, facilities managers, local authority highways engineers, contractors, and manufacturers and suppliers. 8 pages.
