Research on Performance of Asphalt Concrete and Microcosmic Analysis of Its Reinforcing Mechanism

This paper provides guidance for the use of asphalt concrete materials through the study of the action mechanism of asphalt concrete materials and the specific test results. Fiber-asphalt concrete is selected as an example and different mixtures are used to conduct indoor tests. The results show that after 0.3% fiber is added to the asphalt concrete material, the dynamic stability of the material itself has been significantly improved, with an average increase of 20%. It can be found through the experiment that the addition of different mixtures has different effect on the overall performance of the asphalt concrete material and the performance of the concrete has been significantly improved with the addition of fiber. The enhancing effect of fiber material on the performance of dense-graded concrete material is the most significant.
