The Applied Research Of Mixture Composed With Breakstone And Lime-Soil In Jinan City

City Road is an important infrastructure of national economic development,playing an increasingly important role in. In order to avoid the effect caused by increased with repeated, city road service life of vehicle load and the external environment of the early failure of pavement road base material, choose road base course material is the key. This paper takes Jinan Long Ao Bei Lu road entity project,construction technology and strength formation mechanism of lime macadam are analyzed and experimental research, provides the theory support for the design and construction of Long Ao Bei Lu lime macadam base.First, test performance of the various of lime soil gravel materials, analysis of effect of various components on the formation of lime stone strength, and then in the field than select the appropriate material. The maximum dry density, gradation of the determination of lime content and lime soil compaction effect of titration, gravel compaction of soil analysis, and then draw the mix ratio test.Secondly, through test road paving to verify the rationality of lime gravel mix.Study of paver, road roller, effect, influence factor analysis of lime gravel compaction,lime stone construction process is put forward. Especially pay attention to moisture and the segregation control in the construction of lime gravel mixture to ensure the engineering quality. Study of this important link maintenance lime macadam paving after.Finally, put forward Long Ao Bei Lu lime macadam construction technology.Analyze the various defects existing in construction, puts forward the method of quality control and quality control parameters.
