ANALYSIS OF CURLING MOVEMENTS AND CALIBRATION OF PCP PROGRAM. INTERIM REPORT

The long-term work plan at the initial design phase of the McLennan County prestressed concrete pavement (PCP) overlay consisted of the determination of the variables that are relevant to design, the development of models and design procedures, and the study of the effect of environmental factors on PCP slabs. The present study focuses on the evaluation of the performance of PCP. The existing models for PCPs are discussed. Next, the use of collected data in an experimental field section for comparison against program PSCP1 is made. A new model for the prediction of curling in slabs caused by temperature variations is developed and tested. Program PSCP2 is introduced as the result of the upgrading in the models and calibration of models. Finally, conclusions and recommendations based on the instrumentation program, data analysis, and model are outlined.
