Chip seal is most frequently used as preventive maintenance (PM) treatments on asphalt pavement. However, it’s difficult to make the performance test of chip seal in laboratory. In this paper, the specimen molding method of chip seal is established in laboratory. Firstly, considering the structure and technique condition of the original pavement, a cushion layer of asphalt concrete (AC) is used as under layer of the specimen. Secondly, the construction process of chip seal is simulated in laboratory, which includes spraying emulsified asphalt and/or glass fiber, spreading aggregate, initial rolling and conservation, post-stage rolling and conservation in interval for some time. Lastly, visual inspection and sand patch test are used to evaluate the quality of the specimen. Research results show that the method of specimen molding and test in laboratory could relatively accurately simulate, evaluate and forecast the performance of the chip seal.

Application Scope

With the rapid development of science and technology, the application scope of computer technology and related software is expanding, while improving the work efficiency of various industries, the quality of people’s work has also been greatly improved. In particular, as an important part of China’s economic development, the construction industry has gradually applied some new technical means, and achieved remarkable application results. CAD technology drawing can not only improve the standardization of scheme design, but also effectively shorten the time, which is of great significance to the improvement of construction quality. This paper focuses on the application of computer technology (CAD) in the construction of building decoration, and hopes to provide reference and suggestions for relevant personnel.

As an important construction link in the construction project, the quality of the water supply and drainage directly affects the overall quality of the construction project. Because of the strong function of the water supply and drainage project, the construction quality is easily affected by the construction method. For this reason, construction enterprises should attach importance to the mastery of water supply and drainage construction methods. And further understand the relevant precautions of construction water supply and drainage construction, in order to achieve the purpose of improving the quality of water supply and drainage construction.

Municipal road and bridge engineering is an important part of the transportation road construction in the city. Its construction quality directly affects the transportation quality and driving safety of the whole municipal road traffic. Among them, the foundation engineering of municipal road and bridge engineering is the main construction link. In the current municipal road and bridge construction process, it is often affected by many factors, leading to the reduction of the construction quality of municipal road and bridge engineering, especially the construction treatment of soft soil foundation in the foundation engineering, which is the main factor directly affecting the construction quality of municipal road and bridge. This paper first introduces the definition and relevant characteristics of soft soil foundation in the construction of municipal road and bridge engineering, and expounds the influence of soft soil foundation on municipal road and bridge engineering, and then analyzes the application of soft soil foundation treatment technology combined with the basic treatment ideas of soft soil foundation in the construction of municipal road and bridge.
