Abstract

Low skid resistance of road marking paint is one of the major issues in the safety of vehicle drivers, cyclists, and pedestrians when traveling on the city streets. Among the variety of marking paint, two-component paint is widely used at intersections and roundabouts. Therefore, the paint used should have adequate skid resistance. The object of this study was to evaluate the skid resistance and other physical properties of twocomponent road marking paint that is widely used in Tehran. Several additives were used and with the use of a British Pendulum Skid Resistance Tester, the skid resistance values (SRV) of the specimens were determined. In addition, abrasion resistance, reflectivity and adhesive properties of the specimens were evaluated. The tests results showed that the conventional road marking paint has a poor skid resistance. The problem may be resolved by using additive materials such as waste glass powder, silica granules and Lika (i.e. expanded clay). Results suggest that waste glass powder has shown a better performance than the other additives, as it enhances the skid resistance of the paint. According to the pendulum test values, the application of waste glass powder as much as 10% by weight of road marking paint may respectively increase the skid resistance and reflectivity up to 21 units (from 38 to 59) and 40 units (from 239 to 279) so that it does not impose much negative impact on the other properties of the paint. It was that the additive materials caused a reduction in the abrasion resistance of the road marking paint.
