Flexural fatigue evaluation of cement-treated mixtures of reclaimed asphalt pavement and crushed aggregates
چکیده انگلیسی

•Reclaimed asphalt pavement and crushed aggregates mixtures were cement treated.•Evaluation of fatigue life of cement-treated mixtures of RAP and crushed aggregates.•Flexural strength, strain at break, flexural static modulus and resilient modulus.•Strain based fatigue relationships used in mechanistic pavement analysis.

This paper evaluates the fatigue behavior of cement-treated recycled pavement materials. Six mixtures with different cement contents and reclaimed asphalt pavement (RAP) percentages were tested under static and cyclic flexural loading. Cement content was the main factor affecting strength, whereas RAP percentage showed major effect in strain at break. Similar moduli were obtained under both loading conditions, which is useful for design by allowing estimating resilient modulus through static results. Tests results and mechanistic analysis showed that the fatigue life of cement-treated recycled bases depends on the mixture composition and on the thicknesses of asphalt wearing courses and recycled layers.
