• Abstract:
  In the last several years, both reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) have been widely used in paving Texas highways. Compared to RAP, RAS has two features: 1) much higher asphalt binder content, and 2) super stiff asphalt binder. Thus, the use of RAS can not only reduce the cost of asphalt mix paving significantly, but it also conserves energy and protects the environment. However, the super high stiffness of RAS binder causes strong concern on durability (or cracking performance) of asphalt mixes containing RAS. Another concern was the variability of processed RAS due to different RAS sources varying from manufacture waste shingles to a wide variety of tear-off shingles.
