A REVIEW OF THE INTERNATIONAL USE OF LIGHTWEIGHT CONCRETE IN HIGHWAY BRIDGES

The report reviews the use of lightweight concrete for highway bridges in North America, the USSR, Poland, Western Europe and the UK. It discusses the scale of the use of these structures, economic advantages and the prospects for increasing their use in the UK. The types of bridge in which lightweight concrete has been used range from simple reinforced concrete foot bridges to long-span post tensioned segmental box girder bridges. Weight savings of 25 to 30 per cent on the superstructure can be achieved in some cases. Overall cost savings of 10 per cent or more are possible once allowance has been made for the higher initial cost of the lightweight aggregate. Lightweight concrete bridges have generally performed satisfactorily in service. In particular the use of lightweight concrete is suggested for precast prestressed components to reduce handling costs where access is limited, as for local road improvements and urban renewal schemes, or where ground conditions are difficult.
