Abstract
An improved understanding of the rheological and engineering properties of a rubberized asphalt concrete (RAC) pavement that contains reclaimed asphalt pavement (RAP) is important to stimulating the use of these recycled and by-product materials in asphalt mixtures. The uses of RAP and rubberized asphalt in the past have proven to be economical, environmentally sound, and effective in hot mix asphalt (HMA) mixtures across the US and the world. The objective of this research was to investigate the binder and mixture performance characteristics of these modified asphalt mixtures through a series of laboratory tests to evaluate properties such as the fatigue factor G*sinδ, rutting resistance, resilient modulus, and fatigue life. The results of the experiments indicated that the use of RAP and crumb rubber in HMA can effectively improve the engineering properties of these mixes.
