Wear resistance test and influencing factors analysis of asphalt pavement
Based on the asphalt pavement project constructed in Fuzhou Binhai New Area,in order to analyze the attenuation law of the wear resistance of asphalt pavement materials,combined with the vehicle load and environmental influencing factors affected by asphalt pavement during service,this paper uses self-made asphalt pavement material wear resistance instruments to carry out the wear resistance law test of asphalt mixture of different graded types,the wear resistance law test of asphalt mixture with different load sizes,and the wear resistance law test of asphalt mixture under the action of water environment.The results show that the wear resistance of different graded types of asphalt mixture is different.The larger the load,the faster the structural depth and pendulum value of the asphalt mixture specimen decay,the less time required to reach the stable value,and the final value of the structural depth decreases with the increase of the load,and the final value of the pendulum value is basically the same.Under the same wear time,the construction depth and pendulum value of the asphalt mixture worn in the water environment are lower than those in the dry environment.The attenuation law of the wear resistance of asphalt pavement materials can provide support for the improvement of wear resistance of asphalt pavement.
