Performance of Pavement Plate Reinforced with Modified Unsaturated Polyester Fiberglass Reinforced Plastic
In order to study material performance of modified unsaturated polyester Fiberglass Reinforced Plastic (FRP) pavement plate and its application in rapid crater repairing on airfield pavement, experiments were conducted to test its flexural and direct tension strengths; and the loading-vehicle was used to simulate one type of airplane to run on the repaired pavement with the FRP plate hundreds of times. It was discovered that the optimal mesh size of fiberglass in FRP plate was 120; the flexural tension strength of the plate could reach 240MPa; the direct tension strength of that could reach 200MPa; and the direct tension elastic modulus of that is larger than 15GPa. These data indicated that the toughness and the performance to resist flexural tension damage of the reinforced material were better. The results indicate that the damage to FRP plate was mainly induced at joints between the plate and subgrade. The flexural deflection not more than 5 cm could be served as a standard to judge whether the repaired pavement could be used continuously.
