Evaluation Of Louisiana Asphalt Pavement Friction, Vivek Lal Das
LSU Master's Theses
This study aims to comprehensively investigate the effect of asphalt mix designs to address skid resistance. The current Louisiana Department of Transportation and Development (LADOTD) specification for friction design considers only the friction rating of aggregate defined by the polished stone value (PSV) obtained by the British pendulum tester (BPT), which is associated with only the micro-texture of asphalt pavement surfaces. The objective of this study is to recommend an asphalt surface friction mix design guideline which is based on both micro- and macro-texture of the wearing course mix. The objective was achieved by evaluating four typical laboratory prepared Louisiana …
