Experimental and Economic Analysis of Airport Crumb Rubber Concrete (CRC) Pavement

The feasibility of using crumb rubber concrete (CRC) in airport pavement is discussed by analyzing the capability of crumb rubber concrete. The bending property of CRC is studied by four point loading test of small-sized rubber concrete beams. Comparing with cement concrete (CC) pavement, the board thickness of CRC pavement is analyzed. The conclusions are reached that appropriate mixing of crumb rubber could satisfy strength demand and improve durability of airport pavement, and the thickness of CRC pavement is 93 percent of that of CC pavement. As a result, airport CRC pavement has longer service life and perfect cost performance.
