Portland Cement Concrete Pavement

Over the past years there has been an increasing interest in recycling construction materials, particularly hot-mix asphalt (HMA) and portland cement concrete pavements (PCCP). To this end the Kansas Department of Transportation (KDOT) participated in Demonstration Project 47, Recycling Portland Cement Concrete Pavement, by recycling a moderately D-cracked concrete pavement and monitoring the performance over a 10-year period. The recycled concrete pavement (RCP) aggregate was evaluated in four test sections consisting of two control sections, one test section of portland cement-treated base (CTB) with RCP aggregate, and one test section using RCP aggregate in the PCCP and CTB. An HMA shoulder using RCP as coarse aggregate was also constructed. The test sections were monitored over a 10-year period for performance including faulting, roughness, load transfer, and friction measurements. Faulting, roughness, performance level, and joint distress measurements from KDOT's 1995 pavement condition survey were used to compare the performance of the recycled sections with PCCP of similar age and traffic in the same area of the state. All test sections performed well, with the CTB and PCCP sections with RCP aggregates showing slightly more distress.

Portland Cement Concrete Pavement

This paper describes the calculation analysis of joint open, and the research has been carried up on Portland cement concrete pavement and rubberized concrete pavement with the consideration of hogging distortion caused by temperature, expansion deformation and drying shrinkage. Finally ,it were observed that joint open of 6m contraction joint spacing for rubberized concrete pavement is the same as 4.5m contraction joint spacing for Portland cement concrete pavement. The above analysis provides the possibility of 6-meter contraction joint spacing for rubberized concrete pavement which give theoretical basis for engineering application.
