复合式路面沥青层稳定性研究

Stability Analysis of AC Layer on the AC/RCC Composite Pavements

碾压混凝土与沥青混凝土复合式路面结构研究中，沥青层的稳定性是一个不容忽视的问题，对碾压混凝土与沥青混凝土层之间剪切、沥青混凝土层车辙等进行理论计算及室内试验，提出了稳定性设计方法建议。

For AC/RCC composite oavement structure,the stability of AC layer can not be negligenced.In this paper,elastic multi-layer theroy,with double-circle load,is used to calculate the shearing stress between AC and RCC.Elastic-viscocity multi-layer theory is used to analyse the rut of AC layer.Indoors experiments on the interlayer shearing strength and AC rutting are carried out.Combined with all the results obtained,a stability design method is recommended.
