Highway Pavement Typical Structure Of Long-life Technology

In this paper, references long-lasting pavement's definiens of our country and foreign countries, bring that composite pavement is a good way to realize long-lasting pavement. On base of composite pavement's study on RCC+AC, calculates and analyses PCC+AC, a typical configuration of composite pavement. Uses finite element method as an assistant tool, to calculate and analyses the shearing stress of layer between AC and PCC. It is important to set the interlayer. Calculates and analyses temperature stress and load stress of PCC. On this foundation, brings a method of predicting life, and calculates over-loading's negative influence. This paper research roundly PCC+AC composite pavement of long-lasting pavement's typical configuration, the research result will even play an active role to generalize the long-lasting pavement in Henan province and whole country.
