Longitudinal Cracking in Widened Portland Cement Concrete Pavements
The Wisconsin Department of Transportation constructed certain concrete pavements with lane widths greater than the standard 12 feet in order to reduce stress and deflection caused by vehicle tires running near the edge of the concrete slabs. Many of these pavements are approaching 20 years of service life and some are experiencing longitudinal cracking. Research was needed to determine whether the use of wider slabs made the pavement more susceptible to other forms of distress. This study investigated the occurrence of longitudinal cracking in doweled jointed plain concrete pavements (JPCP) to determine the maximum allowable pavement width as a function of pavement thickness in order to achieve optimal JCPC performance. A set of guidelines was developed for JPCP panel width usage. The researchers evaluated and statistically compared the performance of doweled JPCP having wider panels (14 and 15 feet wide) to the performance of concrete pavements with standard with panels (12 to 13 feet), while incorporating the interactive effects of other variables. The investigation was limited to doweled JPCP aged 25 years or less. A standard panel width of 14 ft with a width-to thickness-ratio in the range of 1.2 (12 in thickness) to 1.5 (9.5 in thickness) was found to minimize cracking severity and extent.
