ASPHALTIC CONCRETE PAVEMENTS OVER WATERPROOF MEMBRANES ON CONCRETE BRIDGE DECKS ---PROCEEDINGS OF THE THIRTY-SECOND ANNUAL CONFERENCE OF THE CANADIAN TECHNICAL ASPHALT ASSOCIATION

The city of Saskatoon has five bridges over the South Saskatchewan river, each approximately 350 metres long. Despite adherence to the best known design and construction standards, premature failures have occurred, resulting in substantial costs and inconvenience to the public. The failures were caused by paving at low temperatures, inadequate pavement stability and thickness, substandard protective cover over the waterproof membrane and deterioration of the membrane itself. The paper describes the experiences of the city with bridge deck failures in connection with saskatoon's recent bridge deck rehabilitation program. The paper also describes the specifications and procedures developed and used successfully for asphaltic concrete pavements having waterproof membranes to protect the concrete deck. With the development of a durable concrete wearing surface and the use of a high quality waterproof membrane system, future bridge maintenance should be reduced substantially.
