Role of Modified Asphalt Binders in the Performance of Pavements
The study had the objective of (1) exploring the effect of three commercially available asphalt modifiers in improving the mechanical properties of asphalt paving mixtures; (2) evaluating the effect of these modifiers on mitigating pavement distress and improving the overall pavement performance of pavement sections that are identical in all other layers, except in the top asphalt layer; and (3) assessing the economic feasibility of using these modifiers. The modifiers investigated were carbon black, neoprene latex, and polymerized asphalt (STYRELF). The dense graded asphalt paving mixture specimens were subjected to dynamic and creep tests at varying temperatures, and the mechanical properties that were determined included resilient modulus, creep, permanent deformation parameters and fatigue life. Based on these properties, the VESYS IIIA pavement performance prediction model was utilized to assess the improvement, if any, of the modifier on the pavement distress and the overall performance.
