- Research was done in three general areas: material properties of polymer-impregnated concrete, repair of deteriorated and delaminated bridge decks, and polymer impregnation of new deck surfaces. Structural and durability properties of impregnated normal and structural lightweight concretes were measured. Effects of temperature and cyclic loading were investigated and bond pull-out strength of reinforcement was measured. Process variables studied include monomer type, method of polymerization, aggregate type, and air content of the concrete. Compared with the controls, the properties of MMA-impregnated samples were improved by factors ranging from 2.6 to 4.5. Use of polymer-impregnated concrete to prevent chloride penetration into bridge decks was demonstrated and prototype deck panels have been evaluated. Impregnation offers a potential solution to the bridge deck deterioration problem. Impregnated curbstones are also being tested. Techniques for repairing highly deteriorated and delaminated bridge decks by monomer impregnation were demonstrated in field tests in which a 6-in.-thick section of deck was impregnated. Cores taken from the reconstituted deck had compressive strengths and water absorptions of 5000 psi and 1.6 percent, respectively. Plans to repair an entire deck are being formulated by NYSDOT. Low-viscosity monomer systems that can be used to repair delaminated concrete have been developed. (auth)
