BRIDGE DECK RESTORATION METHODS AND PROCEDURES, PART III-EXPOSED MEMBRANE SEALS ON BRIDGE DECKS (INTERIM REPORT IV)

This report evaluates some 25 installations of bridge deck exposed membrane seals. Each installation is discussed in detail and test performance record for each is included. Each installation is rated as acceptable or not acceptable. All installations of one membrane type are collectively evaluated as to the suitability of the membrane for contract useage or for further testing. All California Standard Specification epoxy installations are evaluated as failures. A proprietary epoxy asphalt chip seal is rated as a failure in 8 test installations due to porosity, although aggregate retention was good. A proprietary urethane is rated as a failure in 4 test installations due to porosity and poor aggregate retention with one installation debonding extensively from the deck. Another proprietary urethane (PRC 445/440) is rated as a fully successful exposed membrane and is recommended for contract use. /FHWA/
