The Use of Recycled Asphalt Products in Asphalt Pavements

Reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) are two of the most commonly used recycled materials in the world. Recommendations as to their use and handling in Connecticut need to be made in order to increase the amount of RAP that may be introduced into the mixture and also to make determinations as to the benefits and total quantity of RAS that should be used. Connecticut Department of Transportation (CTDOT) constructed three pilot projects utilizing RAS, RAS with RAP and then varying quantities of RAP from 15%-40%. The projects are summarized in this research. Performance tests show comparisons between the test sections and control sections. Density analysis shows that increasing RAP quantities beyond 20% should be avoided at this time. Recommendations are made to continue monitoring these pilot sections in order to determine the longer term effects of the recycled products.
