Polymer Modification Technologies and Asphalt Mixtures Fatigue Resistance in Pavement Structures

This paper focuses on polymer modification technologies and pavement durability in relation to fatigue resistance, providing a critique of several common mix design practices and recommendations based on recent research findings in relation to pavement field performance. The authors present specific data measurements from the laboratory of fatigue resistance behavior for asphalt mixtures with various bituminous binders: neat, polymer-modified, and chemically-modified asphalt binders. Results show differences in calculated pavement design lifespans when a 50% loss modulus as a standard concept is employed in contrast to a dissipated energy concept. The authors also describe the variability of asphalt mixture fatigue resistance and the stochastic method for calculating a proportional coefficient. Proportional coefficient implementation in pavement design methodologies may enhance consistency in pavement design lifespan predictions and subsequent in-situ performance. The methodology presented in this paper can be utilized to analyze the longevity of the material on steel bridges as will be envisaged in the research project.
