By David Reed, UT EditorBoucherville, Quebec-Solicor USA Inc., a wholly-owned subsidiary of Canam Group Inc. specialised in the fabrication and marketing of the new SPS (Sandwich Plate System) technology, has secured its first bridge contract in the United States. The contract is for the design, construction and erection of a bridge in Virginia. The bridge deck will be built using SPS technology and will incorporate a thin, factory-manufactured wearing surface, a brief statement from the firm indicated.The SPS process was invented and developed by Intelligent Engineering of Canada and Elastogran GmbH in Europe. It comprises a 20- 30mm thick polyurethane elastomer layer sandwiched by steel plates about 10 mm thick. The resulting composite is extremely tough, and the technique has so far been used mainly in replacing decks of roll-on/roll-off ferries and other marine structures where it can be applied in situ with minimal preparation work compared to conventional deck replacement. Most recently, the SPS system was used to replace the deck on a motorway bridge near Krefeld, Germany.”
