An investigation was made to determine the feasibility of using polymer-concrete PC for rapid repair of airfield pavements. The polymer-concrete studied was a mixture of dry aggregate and a methyl methacrylate monomer. Tests were conducted to isolate the variables that affect the strength and polymerization time of PC. Laboratory and field tests were conducted to test the strength, durability, and feasibility of polymer-concrete repairs. The major variables affecting the polymerization time of PC were found to be temperature and chemical composition. Monomer formulations were developed that permitted polymer-concrete to be polymerized in less than one hour at a temperature range of 0 to 100 F. An investigation into the variables that affect strength resulted in several findings. The tests showed that dry aggregate less than 1 moisture is very important for strength. The strength of PC was found to increase with stronger aggregate and smaller pore volume. The temperature of the polymer-concrete was found to affect the strength to a great extent. The higher the temperature the greater the reduction of strength. Author
