<p>A sealed joint in a concrete highway is installed in a channel (14) formed above the shrinkage control cut (12) between adjoining concrete slabs (10, 11) by depositing a mass of uncured ductile and elastic adhesive (15), in such channel (14) and embedding a preformed length of a cured ductile and elastic material (16), in such adhesive (15). The length (16) is of strip formation and respective fillers of an anti-bonding agent (17) to provide for joint expansion and retraction. The joint installation channel (14) is preferably unusually shallow and may be dry cut. Its width is sufficiently narrow that traffic loads are carried by the concrete bordering the channel. Preformed strip (16) is introduced into the adhesive (15) in the channel (14) from a stable roll. The adhesive is less ductile and elastic than is the preformed length embedded therein.</p> |
