Design and Construction of Continuously Reinforced Concrete Pavements

Continuously reinforced concrete pavement(CRCP)is smooth and almost needs no maintenance,which has long service life as well as a promisingly potential application.CRCP is introduced in detail from design factors,structural response analysis,design,construction,and et al.Different from 1993 Design Guide of AASHTO,2002 Design Guide selects punchout development and smoothness as design criteria.The research on CRCP at home has been still far behind that at abroad.Based on the analysis of the faults in previous research on CRCP,it is pointed out that the research on CRCP in the future will be focused on the following aspects:punchouts prediction based on the distribution of transverse crack width and spacing,crack width prediction under repeated vehicle-load and natural conditions,the calculation of the critical transverse stress at the top of the slab when the loss of base support and the Load Transfer Efficiency(LTE)of cracks or joints are considered,the asphalt pavements with the base course made up of continuously reinforced concrete,and the material composition design of different structural course according to their performance requirement.
