Abstract:

The Iowa Department of Transportation (DOT) initiated a failure investigation of higher-than- expected transverse (mid-panel) cracking distresses observed on Jointed Plain Concrete Pavement (JPCP) sections with 20-ft joint spacing on Interstate-80 (I-80) in Adair County, Iowa. The forensic investigation focused on the review of design, construction, and distress history records of the JPCP site provided by Iowa DOT as well as a general review of JPCP transverse cracking mechanisms followed by an analytical study. The research-grade version of the Mechanistic-Empirical Pavement Design Guide (MEPDG) (version 1.100) was used to analyze the JPCP site under investigation to evaluate climatic conditions that prevailed at the time of construction and to compare predicted distresses under different JPCP design scenarios. The nationally- and locally calibrated pavement performance prediction models were employed. In this paper, the results from field visual surveys of the distressed JPCP sections are presented along with a discussion of the findings from the MEPDG analysis. The study revealed that relatively higher concrete slab temperature difference, higher wind speed and sunshine, and lesser precipitation at the time of construction contributed to permanent curling and warping of the slab resulting in premature top-down JPCP transverse cracking. The lessons learned from this study resulted in several useful recommendations to improve future Iowa JPCP design procedures, standards, material selection, and construction specifications.
