This report is recommended to design, materials, construction, and maintenance engineers in highway and transportation agencies concerned with avoiding or alleviating the problems frequently associated with the joint at the interface of Portland cement concrete pavements and bituminous-surface shoulders. The research that is reported consisted of field studies directed at obtaining a better understanding of the influences of the factors that affect the performance of pavement-shoulder joint systems, and laboratory studies aimed at devising test procedures and criteria to apply in the selection of joint sealants to assure satisfactory service. Recommendations are made for joint and shoulder designs and joint construction that should provide improved shoulder and pavement-shoulder joint performance. Specifications are proposed for sealants and sealant application. Guidelines are offered for a field evaluation of the design alternatives that are proposed. (Author/publisher)
