摘要
根据冷再生层厚度以及不同的残留层厚度和模量,建立路面结构力学模型,利用有限元软件对路面结构进行计算,得到残留层厚度和模量的变化与冷再生层层底拉应力的变化规律,分析了残留基层厚度对路面结构的影响。
Structural mechanics model of pavement is established based on thickness of cold recycling layer and thickness and modulus of different residual layers.The regularities of variation of thickness and modulus of residual layer and the regularities of bottom tensile stress of cold recycling layer are obtained by using finite element software to conduct calculation.Influence of residual layer thickness to pavement structure is analyzed.
