发明名称 EXPANSION JOINT FOR ROAD WORKS
摘要 A concrete roadway having a joint between adjacent sections is provided with two plates, one secured upon each section, at the ends. The plates have interdigitating fingers to carry traffic over the joint. The plates are so tightly secured to the concrete by bolting that they remain in compression even when traffic is passing over the joint.
