CONTINUOUSLY REINFORCED CONCRETE PAVEMENT: STRUCTURAL PERFORMANCE AND DESIGN/CONSTRUCTION VARIABLES
A detailed analysis of design, construction and environmental variables that may have an effect on the structural performance of a CRCP is presented in this report. The variables are tied together by theoretical models where possible to allow for extrapolation outside conditions prevailing at the sites investigated. Stress is calculated in the pavement whereupon the number of load applications till failure can be determined. A stochastic model provides the link between number of load application and measurable distress. Since several coefficients are unknown for the strucutral performance of a CRCP, a regession analysis is used to derive the values of these equations. The final equations that can be put together are employed in designing new CRCP and in predicting future distress on existing pavements. This study is part of an evaluation study of CRCP structural performance of highways in the rural districts of Texas and is based on information from two districts in Texas. A gross analysis concentrates on all the highways surveyed but excludes some of the design and construction variables that can only be obatined from construction records. Both studies will be useful in the pavement management system presently employed in Texas. /Author/
