POST CAST HEADERS AT HIGHWAY STRUCTURE EXPANSION JOINTS

A method is needed on most decks having an asphalt concrete (AC) surfacing and expansion joints to prevent the AC from breaking up over the joint. In California, a dam type device called a "header" is used. Headers are narrow strips on each side of the expansion joint that the AC butts against. They are usually relatively thin (about 3 inches). Consequently, they need to be very tough to withstand traffic impact and forces caused from compressed debris trapped in the joint. Many materials have been tried in California in a search for the most durable and inexpensive. This report discusses most of the materials used and their performance. (Author)
