The long-term work plan for the initial design phase of the mclennan county prestressed concrete pavement (pcp) overlay consisted ofthe determination of 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 evaluation of the performance of pcp, with specific observation of horizontal slab displacements caused by changes in temperature, is discussed. The behavior of the pcp is characterized by the results of a field data analysis. The instrumentation of the pcp slabs is described, graphs of measured displacements of the slabs for daily temperature cycles are presented, and a regression analysis of the slab movements is discussed. Finally, conclusions and recommendations based on the instrumentationprogram and data analysis are outlined. This paper appears in transportation research record no. 1286, Design and evaluation of rigid and flexible pavements 1990.
