Misalignment of Dowel Bars in Rigid Pavement Joints
The performance of concrete pavements depends to a large extent upon the satisfactory performance of the joints. Most jointed concrete pavement failures can be attributed to failures at the joint, as opposed to inadequate structural capacity (FHWA, November 30, 1990). Distresses that may result from joint failure include faulting, pumping, spalling, corner breaks, blow-ups, and mid-panel cracking. Characteristics that contribute to satisfactory joint performance, such as adequate load transfer and proper concrete consolidation have been identified through research and field experience. The incorporation of these characteristics into the design, construction, and maintenance of concrete pavements should result in joints capable of performing satisfactorily over the life of the pavement. Regardless of the joint sealant material used, periodic resealing will be required to ensure satisfactory joint performance throughout the life of the pavement. Satisfactory joint performance also depends on appropriate pavement design standards, quality construction materials and good construction and maintenance procedures. This research aims at structurally analyzing the effect of misalignment of dowel bars in rigid pavement joints on the joints performance and suggesting practical remediation.
