Development of Procedures for a Statewide Diagnostic Survey on Continuously Reinforced Concrete Pavements
The report documents the work undertaken in 1987 to develop procedures for a statewide diagnostic survey on continuously reinforced concrete pavements (CRCP), which included the following data: (1) deflections, (2) pavement temperatures, and (3) crack width. The data was used to calibrate a performance prediction model for CRCP in Texas. Since the data needs were quite specific, no appropriate procedure for their collection was found in the literature, and studies were conducted to develop collection procedures for the required data. A preliminary analysis made as a basis for planning these studies is also documented. In the study related to crack width, operator ability to repeat and reproduce data for the crack width measurements was checked; the minimum number of readings per crack was determined; and a literature survey was taken and documented. The development of a procedure to measurement pavement temperature included checking the influences of aggregate type and insulation conditions on temperature estimates, and calibrating models to give temperature and temperature gradient estimates. The phenomenon of heat transfer in solids is briefly discussed, thermocouple principles are explained, and the data acquisition and storage systems are described.
