A system for sealing joints in roadways wherein nose plates are attached to each side of the joint to form a gap between the nose plates. A lower seal element is located in the gap between the nose plates. A vapor barrier is provided that extends between the top portions of the two nose plates. The vapor barrier includes edges that are attached to the tops of the nose plates utilizing anchor caps. An upper seal may be included that is located on top of the lower seal element. The upper seal is formed by applying a liquid sealant over the lower seal element and vapor barrier or by installing a preformed gasket that is anchored to the nose plates using the anchor caps.
