摘要：	Several resin-based binders produced by Ashland Chemical were investigated for use with indigenous aggregates for rapid repair of damaged airfield pavements. The resin was required to be non-flammable and have at least 30 minutes of working time. Only a 1:1 blend of Pliodeck TPO Membrane adhesive and Pliodeck PVC Membrane adhesive were found to meet these requirements. The effects of aggregate type, temperature, and moisture on the polymer concrete behavior were evaluated. Small scale field tests were conducted to optimize mixing procedures, and cylindrical specimens were made to determine compressive strength, tensile strength, modulus of elasticity, and Poisson's ratio. Polymer concrete made with Pliodeck was found to be an impractical material for rapid runway repair because it has a low modulus of elasticity and poor workability. The implementation of Pliodeck polyurethane polymer concrete was not recommended because of the very short working times associated with the coarse aggregate mixtures as well as aggressive foaming and segregation problems.
