TRENDS IN DESIGN AND CONSTRUCTION OF HIGHWAY STRUCTURES IN CANADA

This resume of the bridging activity in canada in recent times makes special reference to the latest trends in design methods, construction techniques and use of improved materials. The author points out that the selection of any structure is based upon economic considerations. The following types of bridges are discussed: the cast-in-place post-tensioned bridges, precast, prestressed beam bridges and steel girder bridges. Standard charts are available for detailing and drafting. Details are given of the use of elastomeric bearing pads and rota bearings and the advantages of prestressed concrete over reinforced concrete are stressed. It is pointed out that durability of concrete decks is affected primarily by sealing, spalling and cracking of the concrete. The need for joint-sealing is discussed and an account of some notable achievements in long span crossings such as the port mann bridge, deas island tunnel and the concordia bridge in montreal is given. /TRRL/
