The grouting technology is that the grouting materials are dry-mixed by a grouting production device and equipment, then water is added and stirred to prepare high-flow state slurry, and the slurry is poured into the gaps of the asphalt pavement with large gaps by a pumping pipeline, so that the pavement is filled and reinforced. The structural strength of the asphalt pavement is greatly improved by the grouting technology, the pavement stability is ensured, and the occurrence of rutting is reduced. The grouting device is an important means for realizing grouting technology and grouting product application, and particularly has higher requirements on production convenience, controllability and stability of material preparation. At present, the grouting industry mainly adopts the steps of pre-mixing and producing all raw materials for grouting to prepare a dry mixed material, packaging, storing and transporting the dry mixed material, then taking the dry mixed material to a construction site for adding water and mixing, and often storing the dry mixed material for a certain time before construction, wherein the material performance can change, and the pre-mixing, packaging, storing and transporting the dry mixed material to the construction site for adding water and mixing not only consumes a great amount of manpower and material resources, but also affects the construction efficiency, and the stability of the pre-produced and stored materials can have adverse effect on the construction quality of a grouting pavement.

Based on the fact that the raw materials of grouting materials are produced in a mixing mode in advance and stored for a certain time and then put into site construction, the asynchronous production mode is complex in working procedure, and the grouting materials are degraded due to the fact that time difference exists between the pre-dry mixing mode, the storage mode and the transportation mode and the grouting construction mode, so that a more reasonable grouting material production system needs to be developed. The utility model provides an integrated grouting material production system based on the method.
