基于耗散能理论的沥青路面温度疲劳开裂分析

Analysis on Temperature Fatigue Cracking of Bitumen Pavement Based on Energy Consumption Theory

该文通过沥青混合料温度循环作用下所产生的温度应力和应变的变化规律,运用耗散能理论分析沥青混合料的疲劳破坏过程,以便在路面维修改造设计中加以应用。

By the variation law of temperature stress and strain produced under the temperature cycling action of bitumen mixture,the energy consumption theory is applied to analyze the fatigue destroying process of bitumen mixture so as it can be applied in the design of the pavement maintenance reconstruction.
