This paper presents the results of a research study to design and structurally test a modular concept for bridge decking, involving prestressed polymer (plastic) impregnated concrete (PIC) panels. PIC has an ultimate compressive strength of 15,000 psi (103.4 MPa) and is almost totally resistant to chemicals and other forms of deterioration. Eighteen panels and several related control specimens were cast for the test program. Static and fatigue tests were performed on single and multiple (three) panel deck units. Static tests were also conducted on the connections between panels and between panels and girders. The ultimate strengths of the PIC panels were twice the predicted ultimate strength. A single PIC panel specimen withstood more than 3,000,000 cycles, and a three PIC panel specimen withstood more than 7,000,000 cycles, which is twice the AASHTO service load, without damage. The overall results of the tests showed that the developed PIC prestressed ribbed section concept was structurally sound and feasible for bridge deck construction.
