Book excerpt: Longitudinal joints of concrete pavements constitute essential elements in the overall functionality and performance of the pavement system. The noticeable deterioration of these joints on some of Kansas highways lead to performing a preliminary study in order to determine the severity of the problem and analyze the design and construction issues that might have contributed to the observed damage. Data was collected from 31 sections of interstate highway in the Kansas City, Kansas metropolitan area. Parameters such as the age of the pavement and sealant, accumulated volumes of total and heavy traffic, type of joint, slab length, slab thickness, concrete strength, steel reinforcement, etc. were analyzed in relation to the observed spalling of the longitudinal joints. The variation of these parameters, with the spalling measures presented in this report, was studied.
