LABORATORY AND FIELD STUDIES ON THE DURABILITY OF THERMOPLASTIC ROAD MARKING MATERIALS
Laboratory methods have been developed for determining the durability of thermoplastic road marking materials under scandinavian conditions (low temperature and high frequency of studded tyres). The wear resistance of 28 different materials at -10 degrees c has been measured in a troger apparatus before and after artificial ageing. The equipment is considered to simulate the effect of studded tyres on the durability of road markings. The hardness of the materials, which also appears to influence durability, has been measured at 20 degrees c with the aid of identation test conforming with din 1996. Durability of the 28 materials in the field has been measured at predetermined intervals over a 2-year period with the aid of special equipment. The validity of the laboratory methods has been assessed on the basis of the results obtained. A classification system for the durability of thermoplastic road marking materials using laboratory tests has been proposed. (Author/TRRL)
