Development of Fatigue Predictive Models of Rubberized Asphalt Concrete (RAC) Containing Reclaimed Asphalt Pavement (RAP) Mixtures
Clemson University, 2006 - 212 pages
In recent years, some by-products such as crumb rubber has been used to save money, protect the environment, and extend the life of asphalt pavements. In addition, the utilization of reclaimed asphalt pavement (RAP) is an acceptable practice in many states around the United States and many countries all over the world. However, the use of RAP containing crumb rubber has not been investigated in great detail, so it is essential to explore whether these materials have a positive effect on the fatigue life of asphalt pavement. In general, previous experience shows that the use of RAP has proven to be cost-effective, environmentally sound, and successful in improving some of the engineering properties of asphalt mixtures. Crumb rubber has also been used successfully in improving the mechanical characteristics of hot mix asphalt (HMA) mixtures in many parts of the world.
