Abstract: In order to accurately study the compressive fatigue properties of composite concrete, a response surface method is proposed to study the compressive fatigue properties of fibre reinforced asphalt concrete. Firstly, fibre parameters, asphalt parameters and matrix concrete parameters are set to complete the preparation of fibre reinforced asphalt concrete. Secondly, the compressive strength, design response surface experiment, stiffness modulus and cumulative damage amount of the specimen are calculated. Finally, according to the response surface results, the compressive properties of the specimens are determined, and the stiffness modulus attenuation characteristics and cumulative damage changes of the specimens are determined. The results of compressive fatigue test show that the influence of asphalt content on the compressive strength of concrete is greater than that of fibre content, and the test accuracy of compressive performance of this method is higher than that of existing methods, and the accuracy of this method reaches 99%.

Keywords: response surface method; fibre reinforced asphalt concrete; compressive fatigue; damage amount.
