The type and amount of movement occurring at the joint determined in a concurrent study 'Temperature Effects on Skewed and Curved Slab-Girder Bridges' was used in the assessment of current standards and specifications used in the design of joint systems using elastomeric sealant materials. Test results form the basis for recommendations to improve the current specifications, test procedures, and design procedures. Various products from Sikaflex, Dow Corning, Koch, and Hilti were used for performance comparisons. 收起
