Embodiment

[0041] see figure 1 - Figure 4 , the present embodiment provides a cement-stabilized macadam pavement construction process, the construction process comprising:

[0042] Step 100: Calculate the mixing ratio of the cement-stabilized gravel mixture, and mix the cement-stabilized gravel mixture. After the calculation of the mixing ratio is completed, mix and stir the raw materials, and use the mixing equipment 400 to mix the mixture. The finished product is stored in the finished product warehouse, and the finished product warehouse is transferred to the construction site by using transportation equipment, such as a transport vehicle, and the finished product is laid on the corresponding roadbed 100 .

[0043] Optionally in this embodiment, the stirring device 400 includes a stirring assembly 410 and a conveying assembly, and the stirring assembly 410 includes a first motor 411, a mixing bucket 412, a stirring shaft 413, a stirring blade 414 and a transmission mechanism 430, an...

Abstract

The invention discloses a construction process for a cement stabilized macadam pavement. The construction process comprises the following steps: calculating a mix proportion of a cement stabilized macadam mixture, and blending the cement stabilized macadam mixture; laying a first cement stabilized macadam mixture layer on the pavement, laminating the first cement stabilized macadam mixture layer,laying a second cement stabilized macadam mixture layer on the upper surface of the laminated first cement stabilized macadam mixture layer, laminating the second cement stabilized macadam mixture layer, and maintaining the pavement until the strength of the pavement is not less than 3MPa. The pavement laid by the construction process difficultly causes cracks, and is long in service life and safeand reliable to use.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a cement-stabilized macadam pavement construction process. Background technique [0002] At present, most of the highways and urban roads that have been built in my country are inorganic binder base + asphalt binder surface layer structure, and most of the inorganic binder bases are cement stabilized gravel. Cement-stabilized crushed stone consists of aggregates and a mortar volume, wherein the aggregates are graded crushed stones, the mortar volume includes water and cementitious materials, and the cementitious materials consist of cement and mixture. The construction method of cement-stabilized gravel is: mix all the materials used in the mixing station with a lime-soil mixer in proportion and mix them evenly, then transport them to the construction site, pave them with a paver, and then roll them into shape. After curing, it is made into a cement-stabilized grav...
