一建市政案例分析题（Case study of municipal construction） A municipal construction case, case analysis problem 1 cases of background data (06 sites) A company for the construction of city trunk road reconstruction project, the structure of two lime soil subbase, cement stabilized macadam and asphalt concrete pavement, construction period requirement in May completed the demolition, construction completed by the end of November. Due to the construction of city road interference factors, with greater technical difficulty, the project department in advance of the construction of technical preparations. Cement stabilized macadam base construction, the project department set up the mixing station in the city; to avoid the peak hours, traffic transportation at night, daytime construction. Inspection found that the cement stabilized gravel surface loose, quality problems of low intensity value. Winter construction scheme based on project selection of asphalt concrete paving construction in the highest temperature all day long time. Through field test, the test section of asphalt concrete pavement compaction degree, thickness and flatness are in line with the design requirements for qualified self inspection conclusion. In order to ensure the timely completion of the project department shall prepare detailed construction schedule, the implementation of dynamic adjustment; after the completion according to schedule, adjust the data of construction are summarized. The problem: The construction technology of 1. preparations of the project should include what content? 2. analysis of cement stabilized macadam base construction of the main reason of quality problems. 3. combined with the construction of asphalt concrete in winter the engineering requirements. The 4. Project Department of the asphalt concrete surface inspection based on? If not sufficient, should be added? Reference answer: 1. the preparation of construction organization design (1 points), familiar with the design documents
