What is Studying the Effect of Contaminated Asphalt Pavement Surfaces on Skid Resistance about?

Skid resistance and road conditions are common road safety indicators; therefore, providing adequate skid resistance enhances road safety. The main concern of evaluating pavement friction is in the wet conditions and the presence of surface contaminants. Thus, it is important to find proper methods for measuring the skid resistance of the pavement surface. Rapid maintenance (removing surface contaminants) plays a major role in restoring surface friction and enhancing road safety. This research aims to evaluate the skid resistance of various types of flexible pavement mixtures at different ages subjected to different contaminants. It also studies the effect of surface maintenance on skid resistance using portable skid resistance testers (the British Pendulum Tester, BPT and sand patch). Three types of asphalt mixes were evaluated; the first was a densegraded mixture (Control Mix), the second was a dense-graded mixture containing Reclaimed Asphalt Pavement materials (RAP Mix) and the third was an open-graded asphalt mixture (Open-Graded Mix). The selected contaminants were water, lube oil, and sand (sand dust). Laboratory tests were performed on all mixes determining British Pendulum
