| Abstract: | To study the bending properties of airport crumb rubber concrete pavement, the influence of the crumb rubber volume fraction on the concrete bending properties by the four point loading test of small sized rubber concrete beams was analyzed. The designed thickness of the airport crumb rubber concrete pavement was estimated and compared with that of the airport concrete pavement. Proposal for the mix proportion of crumb rubber concrete used in the airport pavement was put forward. The conclusion is reached that the bending strength and the bending elasticity modulus of the concrete decrease as the crumb rubber volume fraction increases, leading to the decrease of the thickness of the airport pavement and the amount of the concrete. |
