Stress Analysis of Asphalt Overlay on Old Cement Pavement by Impact of Rolling Technology

Cement concrete pavement road performance gradually decay with vehicle load and environmental factors in long-term effect. When the usability of the road surface reduces down to limiting bottom line standard, it can be used to repair asphalt overlay technique with the advantages of short duration, little impact on traffic road repair service and good performance. According to the force characteristics of old asphalt overlay concrete structure, this paper studies the impact of reflective crack propagation mode, fragments after impact on the asphalt overlay of the stress response with ANSYS finite element numerical simulation analysis, and it reveals the rolling technology can effectively reduce the impact of reflective cracking.
