FATIGUE BEHAVIOR OF A PAVEMENT FOUNDATION WITH RECYCLED AGGREGATE AND WASTE HDPE STRIPS

A lab investigation was conducted to evaluate fatigue behavior of an alternative pavement foundation material containing cement stabilized reclaimed crushed aggregate. Class C fly ash, and waste-plastic strip [high density polyethylene (HDPE)] reinforcement. The primary aim of this research was to evaluate a composite that contained more than 90% recycled materials for use as an alternative foundation layer underneath conventional flexible or rigid pavement. The specific objectives of this study were: 1) to evaluate the flexural fatigue behavior of the new composite, and 2) to evaluate the accumulation of fatigue damage in the material. Results indicate that the fatigue resistance of this material is similar to other traditional stabilized pavement materials. It was found that the dynamic elastic modulus remained approximately constant (degraded slowly) for most specimens up to the end of fatigue life. Fatigue damage computed using a dissipated energy approach showed that the damage accumulation in this material approximately follows Miner's rule for cumulative damage, which is often used in pavement engineering.
