Title: Full-scale-fatigue test on anti-reflective cracking of asphalt overlay
Abstract: Reflection cracks often occur in the overlay on old cement concrete pavement.This paper adopted large-scale-fatigue experimental platform for contrastive experiments of different overlay structures to resist reflective cracking,simulated the initiation and extension process of thermal reflective cracking and load reflective cracking of overlay,and tested the anti-cracking effect of different overlays.The results show that stress-absorbing layer can effectively eliminate the stress concentration phenomenon at joints of cement concrete and avoid the reflective cracking of overlay caused by thermal shrinkage of cement concrete slab and load.But setting fibre grids and geotextile cannot solve the reflective cracking of pavement.4 tabs,7 figs,7refs.
