Abstract


This reference to the definition of long-life pavement at home and abroad , put forward feasible way is to achieve long-life pavement is the use of composite pavement . Learn from the status quo, a typical composite pavement structure - PCC AC -depth study of composite pavement . As the main reference to existing research on the RCC AC Composite Pavement PCC AC Composite Pavement Shear stress study , indicating the importance and necessity of a stress sandwich . PCC AC Composite Pavement PCC bottom of the plate board bending tensile stress and thermal stress calculation and analysis, analysis of the variation of the PCC AC Composite Pavement PCC Board To Board end of the maximum flexural stress and temperature stress with impact factors . And based on the a limit life prediction model , calculated sensitivity factors limit the life prediction . Based on the model , calculated overload material adverse effect on the life of the pavement . Black and analyzed the role of the cushion through the calculation, the black cushion the stress is smaller , will not damage cushion . More systematic study of the typical structure of long-life pavement - PCC AC composite pavement , long-life pavement in Henan as well as the promotion of the country has a certain reference .
