Study on the Abrasion Resistance of Water-borne Traffic Lights by Abrasion Test Machine, in Wet Conditions

Abrasion resistance of water-borne traffic paints caused by traffic flow is one of the most important challenges in urban traffic management. Road marking policy should be made in a manner to assure drivers and pedestrian’s safety. In addition, according to the wide ranges of traffic paints application, the paints with adverse environmental impacts should not be used. In this research abrasion resistance of one type of water-borne traffic paint, used in pavement marking in the city of Tehran, has been evaluated. Wet Track Abrasion Test was performed on samples at different conditions. Moreover field works in several streets of Tehran have been evaluated by means of different methods. The evaluation process consists of AS/NZS 4049 and EN 1824.According to laboratory testing results, the water-borne traffic paint used, had good performance in dry conditions. In addition, its performance in simulated winter maintenance conditions (i.e. in presence of sand and salt) was studied. This type of paint showed to have less environmental impacts and exhibited greater retro- reflectivity in comparison with solvent-borne traffic paints. The easy method of application of these types of paint makes them appropriate alternatives for pavement marking operations.
