WINTER 1991-1992 CRACK AND PATCH SURVEY RESULTS

This report presents winter 1991-1992 crack and patch survey data on Iowa's primary and interstate highway systems. The survey is performed every two years to provide data on the physical signs of deterioration that are occurring on a road segment. The various parameters noted and quantified include Design, Construction, Materials and Maintenance related features. Data concerning cracking, patching, and asphaltic concrete rut depths are used to determine correction values which, when subtracted from the IJK Roadmeter results, yield the Present Serviceability Index for a road segment. Data concerning D-cracking, faulting, concrete rut depths, and asphaltic concrete cracking were also gathered in this survey.
