Sustainable Materials For Pavement Infrastructure: Design And Performance Of Asphalt Mixtures Containing Recycled Asphalt Shingles, Samuel B. Cooper, Jr

LSU Doctoral Dissertations

As the price of liquid asphalt continuously climb, methods are being sought to decrease material costs which will have less impact on ecological systems without compromising material or pavement performance. The use of recycled materials is one method that can replace a percentage of their virgin counterparts, thus reducing the negative impacts on the environment. Asphalt mixture performance is affected by the level of blending that occurs between aged and virgin asphalt binders. The interaction and compatibility of recycling agents (RAs) with recycled asphalt shingles (RAS) and reclaimed asphalt pavements (RAP) have not been thoroughly evaluated since the 1970s. To …
