Abstract:

In the recent years, highway engineers introduced skewed joints in the concrete pavement with a 4 foot to 5 foot skew on a 24 foot width pavement, which results in only one wheel crossing the joint at any one time. Subsequently, a skewed joint is expected to reduce load induced stresses and improve riding quality across the joint. However, despite of precise design and construction of concrete highway pavements, some of concrete pavements (example: Interstate-10 and -75 in U.S.A. and 88 Olympic highway in Korea) has already shown severe signs of longitudinal and transverse cracking, faulting, and pumping before the end of their intended service life. Subsequently, this research was performed to study an analytical behavior of concrete pavements, especially for the effects of skewed joints on concrete pavements. This research should provide highway engineers with more structural behaviours and answers on concrete pavement failure problems.
