Thin Overlay South 154th Street Overcrossing 5/523 E

Description: The Washington State Department of Transportation is conducting experimental field evaluations of selected polymer concrete thin (1/4 inch) overlays. The polymer concrete material is manufactured by private industry firms and installed on selected bridge decks under standard Washington State Department of Transportation construction contracts. Approximately 24 bridges will be involved in the experiment; eight of these are included in federal participating construction projects as experimental features.
A polymer concrete thin overlay, The Conkryl Paviour Broadcast System (methyl methacrylate), was applied to the deck of the South 154th Street Overcrossing, Bridge No. 5/523E, under Contract No. 3354, SR 405 Tukwila to South Renton HOV Lanes. This bridge is a prestressed girder bridge located on mainline I-5 at the intersection with I-405 in Seattle, Washington.
