Abstract:This report focuses on (1) the observations and findings from the short-term monitoring of the special test sections constructed in Houston, Texas, and (2) the calibration of the CRCP failure prediction model in the CRCP-7 computer program. To determine whether the performance of pavements in the field is in accordance with that predicted by the CRCP program, special test sections were constructed at four different locations in Houston. For approximately 1 month after construction, the behavior of the pavements was monitored for temperature (both air and concrete), slab movement, and cracking. Although additional long-term condition surveys should be scheduled to draw further conclusions from this test-section study, much valuable information about the early-age behavior of CRCP was obtained during the short-term monitoring. Major observations and findings from the test sections include (1) the importance of the heat of hydration on the early-age behavior of CRCP, (2) the effect of construction season and time of placement during the day on the early-age cracking, (3) detrimental characteristics of the early-age cracks in terms of their shapes and widths, (4) the effect of coarse aggregate type on cracking, (5) factors affecting crack width, (6) determination of setting temperature used as a reference temperature in the calculation of the temperature-induced stresses, and (7) correlation between the shrinkage of concrete pavement in the field and that of lab-cured cylinders.
