Behavior of Long Prestressed Pavement Slabs and Design Methodology

摘要

The main objective of the study is to present the development of a model to predict the behavior of long PCP slabs and incorporate the predictions from the model into a design procedure. In the study, the derivation of a model for friction considering its inelastic nature is presented. The working scheme of computer program PSCP1 which incorporates the major findings from the study is also shown. The information generated by the program can be used for designing thickness, prestress level and slab length of the PCP. To check the reliability of the models inside PSCP1, a comparison of predicted responses from the model is made against responses observed at the McLennan County PCP overlay. A scheme for a design methodology based on design charts and predictions from computer program PSCP1 is finally presented.
