摘要：
Since many influencing factors on the bending property of asphalt mixture, in order to explore the various factors on the influence degree of bending property, 16 kinds beam specimens of asphalt mixture, formed by different asphalt binders and different gradations of aggregate, were tested. Then the mechanics parameter such as the bending strength and failure strain were calculated. The influence degree of eight factors on the bending properties was analyzed by the gray entropy method. The result show that asphalt Brookfield viscosity exert significant influence on the maximum bending strain, filler-bitumen ratio and the maximum particle size exert significant influence on the bending strength.
