Statistical Analysis of Early-Age Crack Data from Continuously Reinforced Concrete Pavements in China

Abstract:

Extensive crack width and crack spacing data from recently constructed continuously reinforced concrete pavements (CRCP) sections in China were collected and statistically analyzed in this study. A total of 29 CRCP sections were observed which lead to 1171 crack data. Kolmogorov-Smirnov test result shows that CRCP crack spacing follows a four-parameter Dagum distribution. ANOVA tests show that slab thickness does not have a significant impact on crack spacing. However, slab thickness does have a significant impact on crack width. Further ANOVA test shows that crack width reduces with the increasing of slab thickness. This preliminary result is not consistent with the crack spacing formula in MEPDG where the crack spacing is directly related to slab thickness.
