Graphical procedures are presented for optimum dimensioning of a joint-slab-sealant system coupled with material properties. PART 1 covers an approach for sealing with compression type sealants while PART 2 concentrates on molded-in-place sealants. Horizontal joint movements are emphasized in both cases. While the main emphasis is placed on concrete pavement joint sealing, the methods are also applicable to other joints, such as those in bridges or structures and even cracks. The procedures used to construct each set of curves are given so that the graphs can be adjusted for other joint or crack sealing applications. The paper also outlines areas where more work and data are needed.
