Problems solved by technology

[0003] At present, when the cement-stabilized macadam processing method is used, it is difficult to fill the voids in the macadam skeleton, which will lead to the inability of the filler to be compacted, and will easily cause more cracks in the cement-stabilized macadam base, which will affect the asphalt subgrade, making Cracks in the asphalt subgrade affect the service life of the road

Embodiment

[0030] Such as figure 1 Shown, a kind of cement stabilized crushed stone processing method described in the present embodiment comprises the following steps:

[0031] S1, calculate the mixing ratio of the cement-stabilized gravel mixture, and stir and mix the cement-stabilized gravel mixture;

[0032] S2. Lay the cement-stabilized gravel mixture layer 60 on the roadbed. During the laying process, the vibrating member 50 vibrates the cement-stabilized gravel mixture, and the vibrating member moves along with the laying position of the cement-stabilized gravel mixture;

[0033] S3, after the cement-stabilized gravel mixture is vibrated by the vibrating member 50, the cement-stabilized gravel mixture layer 60 is then rolled;

[0034] S4. Maintain the cement-stabilized gravel mixture layer 60 until the strength of the cement-stabilized gravel mixture layer 60 is no less than 3.5 MPa.

[0035] This method can make the material filling between the gravel skeleton inside the cement...

Abstract

The invention provides a cement stabilized macadam processing method. The method comprises the following steps: S1, calculating the mix proportion of a cement stabilized macadam mixture, and stirring and mixing the cement stabilized macadam mixture; S2, laying a cement stabilized macadam mixture layer on the roadbed, in the laying process, vibrating the cement stabilized macadam mixture by a vibrating piece, and enabling the vibrating piece to move along with the laying position of the cement stabilized macadam mixture; and S3, after the cement stabilized macadam mixture is vibrated through the vibrating piece, rolling the cement stabilized macadam mixture layer immediately. The method has the advantages that the vibrating piece vibrates the cement stabilized macadam mixture just falling on the roadbed, so that the cement stabilized macadam mixture on the roadbed is uniformly laid, materials among macadam frameworks are more fully filled, the cement stabilized macadam mixture layer can be compact through rolling, and the cement stabilized macadam mixture layer does not crack.

Description

technical field [0001] The invention relates to the technical field of municipal construction, in particular to a cement-stabilized gravel processing method. Background technique [0002] At present, most of the highways and urban roads in my country have been built with inorganic binder base and asphalt binder surface layer structure, of which the inorganic binder base is mostly 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 gravel base. Th...
