In the actual construction process, it is particularly important to strengthen the quality control of highway pavement construction, which needs to arouse the attention of relevant personnel. This paper mainly analyzes the key points of construction technology in highway construction, defines the quality control method of highway pavement construction, and provides theoretical reference for highway construction in the future.展开更多

The tr...In order to shorten the gap between urban and rural areas, the state builds roads and bridges in rural areas, which not only drives the development of rural production but also facilitates peoples daily travel. The traffic volume of roads in rural areas is lower than that in cities. In contrast, the performance requirements of roads in rural areas are lower, and cement concrete pavement is often used. Concrete pavement is widely used in rural road construction because of its advantages such as high strength, strong pavement stability and long service life, but it is affected by factors such as low quality of technicians and limited construction equipment. Many rural cement concrete pavements have a short service life. This paper will focus on the analysis of the construction process, key difficulties and how to improve the construction quality of cement concrete pavement in rural areas. I hope this article can provide reference for rural highway engineering construction.展开更多

By reforming the application of asphalt pavement construction technology in highway construction, the overall application level of asphalt pavement construction technology in highway construction can be improved to a certain extent.展开更多

The research project is guided by surface theory, mortar theory, strength theory and asphalt concrete regulations, based on solid engineering practice, aiming at breaking through the bottleneck of Asphalt Mixture Construction under low temperature environment, through repeated tests and optimization. Carry out a series of studies including the selection of warm mix agent, the formula, road performance and construction technology of warm mix asphalt mixture, and start from four aspects: the selection of warm mix agent, the proportion and technology of warm mix asphalt mixture, the road performance of warm mix asphalt mixture and the construction technology of warm mix asphalt mixture expressway. It has formed a complete set of technical scheme and control standard system for selecting and determining the optimal type and dosage of warm mix agent, reasonable raw material ratio, mixing process and parameters, road performance and applicability of warm mix asphalt mixture, and construction of warm mix asphalt process in low temperature season of asphalt pavement engineering.展开更多
