2009年二级建筑师市政工程模拟卷部分题与答案（2009 grade two architects municipal engineering simulation volume part of the questions and answers） In 2009 two construction division of municipal engineering simulation volume part of questions and answers A RadioButtonList (a total of 20 questions, 1 points for each question. Each item options, only 1 of the most to do) The scene (a) A city trunk road road structure: subgrade filling, the filling height is 2 3M; the road is 12% lime soil base 150mm, lime flyash gravel base 150mm asphalt concrete layer (coarse grain type in 40mm 60mm, total 100mm, total 410mm thickness). Because of the demolition, road engineering construction organization in winter. According to the scene (a), answer the following questions: 1, using any kind of mechanical rolling compaction of soil subgrade, should be controlled in the best soil moisture (+) within the compaction. A1% B2% C1.5% D2.5% Answer: B Analysis: the optimum water content of water stability is the best. The above layer 2, the city main road and expressway are needed by () to test the anti rutting ability. A Marshall test B high temperature rutting test C asphalt aggregate ratio test D residue test Answer: B Analytical: 3, about the asphalt mixture construction technology requirements, the following statement is wrong () A asphalt concrete pavement aggregate maximum particle size should be increased gradually from top to bottom, middle and bottom layer of asphalt mixture aggregate maximum particle size should not exceed the thickness of the 1/2. The most important B asphalt concrete pavement are advised to repair 100 200m test section, mainly divided into trial mix test at two stages, and obtain the corresponding parameters. The end of the C hot mix asphalt pavement construction after natural cooling, the surface temperature is lower than 600C, can allow vehicles to pass. D hot mix asphalt layer and two adjacent radial transverse joint construction should be staggered over 1m. Answer: C Analysis: wh
