摘要
分析了连续配筋混凝土刚性基层复合式的优缺点,并根据各层的功能性特点,分析其各结构层的材料类型及合适的厚度范围,提出"按连续配筋砼基层作为计算疲劳层,将沥青表面层作为大修年限"的理念进行长寿命路面结构设计。最后分析了各路面结构层的计算参数对其疲劳寿命的影响。
This paper analyzes the advantages and disadvantages of continuous reinforced concrete rigid compound at the grass-roots level,and according to the functional characteristics of each layer,it analyzes its material type and the appropriate thickness of layers,put forward according to the continuously reinforced concrete base as computing fatigue layer,the asphalt surface layer as the overhaul period＂ the concept of long-life pavement structure design.Finally the paper analyses the calculation of the pavement structure layer parameters on its fatigue life.
