Statewide Diagnostic Survey of Continuously Reinforced Concrete Pavements in Texas
The report documents a diagnostic survey undertaken in 1988 to collect the following data on a statewide sample of continuously reinforced concrete pavements (CRCP): deflections, pavement temperatures, crack widths, and rut depths (in some test sections). The data will be used to back-calculate pavement properties necessary to calibrate a performance prediction model for CRCP in Texas. The development of procedures for data collection is documented in a previous report. The report documents the field work and the preparations for it. These preparations consisted of checking operator repeatability and reproducibility for the crack width measurements, verifying reproducibility and accuracy of the devices in measuring temperature at the pavement surface, casting temperature blocks, also called portable slabs, to take to the field, and checking the accuracy and reproducibility of the thermocouples that were put into the portable slabs. The field work, with emphasis on the practical conditions encountered in the field, is described, and data collected are presented. It is expected that the documentation of the experience gained with the preparations for and collection of the diagnostic data will not only serve to report the progress of the project but will also be valuable guidance for any agency needing to undertake a similar survey.
