• Abstract:
  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.
