Abstract
As an important part of infrastructure construction, the quality of road engineering is directly related to traffic safety and traffic efficiency. Asphalt mixture is one of the main materials of road engineering, its mix ratio design and performance study is of great significance to improve the quality of road engineering and prolong the service life. This paper focuses on the design and performance of asphalt mixture for road engineering, aiming to provide theoretical basis and technical support for engineering practice in related fields. This paper describes the basic principle and flow of asphalt mixture ratio design. The design of the mixture ratio of asphalt mixture aims to optimize the ratio of raw materials such as coarse aggregate, fine aggregate, filler and asphalt, so that the physical and mechanical properties of the mixture can meet the engineering requirements. In this paper, the key steps of mix ratio design are introduced in detail, including the selection and testing of raw materials, the determination of the grading range of mineral mixture, the determination of the optimal amount of asphalt, etc., and the influence of various factors on the performance of the mixture is analyzed. In this paper, the performance of asphalt mixture and its evaluation method are studied. The performance of asphalt mixture is directly related to the performance and durability of road engineering, including high temperature stability, low temperature crack resistance, water stability, skid resistance and so on. In this paper, the properties of asphalt mixture were evaluated comprehensively by the method of laboratory test and field observation, and the variation law of the properties of mixture under different mix ratio was discussed. This paper summarizes the main achievements and conclusions of the design and performance of asphalt mixture for road engineering. By comparing and analyzing the performance of the mixture under different mix ratios, this paper puts forward some suggestions to optimize the mix design, aiming at improving the performance and durability of the asphalt mixture for road engineering. At the same time, this paper also points out the shortcomings of the current research and the future research direction, and emphasizes the importance of continuous innovation and technological progress in promoting the development of road engineering.
