Abstract
In this paper,based on the measured"tire-road"interface conditions,the roadbed working area depth of typical asphalt pavement structure under different working conditions is calculated by using elastic half-space theory and layered elastic system theory respectively.The calculation results show that the roadbed working area depth changes significantly with the axle weight.Based on the calculation results,the recommended value of roadbed working area depth is put forward:when the axle load is less than 100 kN,the roadbed working area depth is 0.8 m.When the axle load is less than 130 kN,the depth of roadbed working area is 1m,and for roads with axle load less than 150 kN,the recommended value of roadbed working area depth is 1.2 m.For the soil foundation within the roadbed working area,effective engineering treatment measures must be taken to ensure that the roadbed and pavement structure has sufficient bearing capacity.关键词
