Abstract:

The fatigue behavior, resilient properties, and progressive accumulation of damage due to repeated flexural loads on a fiber-reinforced pavement base course material composed of cement-stabilized recycled concrete aggregate and fly ash were studied. Unreinforced material had a fatigue strength comparable to virtually all typical stabilized highway materials. The degradation of the dynamic elastic modulus due to repeated loading was found to be less than 25% of the initial modulus. The resilient modulus in flexure for this material was found to be comparable to values reported for traditional soil-cements materials.
