Recycled Asphalt Pavement as a Base and Sub-Base Material

摘要: Laboratory and field investigations were conducted to evaluate the use of recycled asphalt pavement (RAP) in roadway base sub-base applications. The laboratory resilient modulus test results showed RAP has comparable strength with dense graded aggregate material used state New Jersey. Using spectral-analysis-of-the-surface-waves method (SASW), testing program evaluated elastic verified results. higher stiffness for than normally
