- Abstract:
- To study the similarities and differences of force and deformation of asphalt pavement under single roundand two round loads, and to verify the effectiveness of using single round uniformly distributed load equivalent two.round uniformly distributed load. Firstly , the deflection and stress of asphalt pavement under two-round uniform dis.tributed load were studied, and then the comparative stress analysis of asphalt pavement under single round and tworound loads based on elastic layer theory and numerical simulation study by dynamic loading of double-and singleround were carried out. The results show that: both in the statie and dynamic load mode, except some differencesexisting in the road surface, with the increase in the depth of the pavement structure, deflection and stress trendsand size are consistent for single round and two round loads, which means that with a single round uniformly distrib.uted load equivalent to two-round to design and testing is feasible and effective.
