Analysis on Construction Technology and Quality Control of Asphalt Pavement in Highway Engineering

Architectural decoration decoration materials are used by people or decorations, the building and space for all kinds of surface treatment, the use of in order to improve the building comfort.In architectural decoration, engineering quality is directly related to the credibility of enterprises and the effect of the project, and use function. In this paper, from the architectural decoration construction technology management and quality control two aspects to discuss. First of all analyzes the optimization measures of architectural decoration construction technology management, the second for the quality control of several factors is analyzed and summarized.

Major Section

As vehicle flow on arterial highway in Inner Mongolia sharply increased, the originally designed natural increase rate of 8% per year has been exceeded on the vehicle flow in some sections. According to statistics, monthly average vehicle flow on major section of G6 expressway has reached a standard flow of 67478 vehicles per day and night, of which in 70-80% are large ones for coal transportation. Therefore, pavement load and road capacity have exceed the designed expressway load capacity. At present, semi-rigid base asphalt pavement structure is still widely used for high-grade highway pavement in Inner Mongolia. With years of construction for such pavement structure, a great deal of valuable experience has been gained on construction technology. However, there are still a few deficiencies in the quality of raw materials, gradation control of asphalt mixture and adjustment of equipment, etc. Hohhot circle expressway connects with the G6 and G7 expressways, suffering from problems such as large vehicle flow and load overweight. This paper introduced a key technique that should be properly controlled during construction of such pavement structure, emphasized technique control and management of the following aspects, i.e. ballast sizes and gradation control, asphalt concrete mixture, adjustment of pavers, validation of mixing proportion in production and reasonable arrangement of process, and summarized corresponding technical measures taken during construction of asphalt pavement in this project.

And Control

According to Chinese traditional classification, large-sized jackets weight over 10,000 tons and stand in over 100-meter water. Large-sized jackets are different from the normal in construction tonnage, structural dimension and quality control requirements as well as construction difficulty. More complicated construction technology and programme, higher grade of materials, stricter control requirements on node weld and higher risks all need matched stricter, more meticulous and more comprehensive management in planning and scheduling. Combined with construction of LW3-1 deep-water jacket, this paper describes the planning, tracking progress, process control and optimization.
