A gasket for use in a bell-and-spigot joint between adjacent concrete box culverts. The gasket includes a body portion having top and bottom surfaces and opposing longitudinal edges. A first protrusion extends from the top surface adjacent one longitudinal edge, and a second protrusion extends from the top surface adjacent the other longitudinal edge. A layer of pressure-sensitive adhesive covers at least a portion of the bottom surface. The protrusions provide sealing contact points between the box culverts.
