Alternative Material Dowel Bars For Rigid Pavement Joints, Purdue Ect Team
ECT Fact Sheets
Over the last thirty to forty years, dowel support of the joint in Rigid Joint Pavement (RJP) has been widely used. The problem of deterioration of concrete pavement joints has resulted in the search for alternate solutions. Fiber-reinforced polymer (FRP) and stainless steel represent corrosion resistant alternatives to conventional galvanized steel in this application. The recently study by the FHWA of Alternative Materials for Highway Construction demonstrated that even with extended wet-dry cycles of exposure to fluids of high chloride content, at various temperatures and PH levels, stainless steel had corrosion resistance hundreds and in many cases thousands of times …

New Structural Material - Fiber Reinforced Plastics, Purdue Ect Team
ECT Fact Sheets
Traditional structural materials are heavy and require a great deal of maintenance. If a new breed of structural material could be produced that was lighter, stronger and more resistant to corrosion, impacts, parasites and chemicals, it could be a good substitute for steel, concrete, masonry and wood. One new material that has the potential to meet these demands is starting to show up on the construction industry market, it is Fiber Reinforced Plastics (FRP). Some technologies that have been developed using FRP materials within the last few years are: structural shapes, concrete reinforcing, prestressing and post-tensioning tendons and pre-engineered structural …

New Infrastructure Repair Method - Fiber Reinforced Plastics, Purdue Ect Team
ECT Fact Sheets
As the United States infrastructure gets older, the need for repair and rehabilitation increases. Most of the constructed facilities are deteriorating at a rate faster than they can be repaired. Thermal setting resins and fiber rods and sheets are being used to repair and upgrade structural systems. High-strength FRP fabric can be wrapped with relative ease around a bridge pier, a concrete column, or a concrete beams. They are primarily used to stiffen columns and beams and to repair deteriorated concrete components.
