Abstract

The invention relates to a roadbase mixture prepared from construction waste resourcefully treated by a dedicated soil stabilizer. The roadbase mixture is prepared from the materials of 93 to 98 weight parts of construction waste powder, 2 to 7 weight parts of cement and 0.01 to 0.1 weight part of soil stabilizer; the soil stabilizer is prepared from 100 weight parts of water, 1 to 15 weight parts of surface active agent and 0.1 to 10 weight parts of boric acid or borate. The roadbase mixture is further prepared from the material of water, and the use amount of the water is 1 to 4% more than the optimal moisture content of the roadbase mixture. The roadbase mixture disclosed by the invention has very good water stability.

Description

technical field [0001] The invention relates to a road base mix, in particular to a road base mix manufactured by using a special soil stabilizer to process construction waste as resources. Background technique [0002] China's construction industry is consuming sand and gravel at a rate of about 7 billion tons per year. The endless exploitation and use of large quantities has caused the depletion of resources in some areas, the destruction of rivers, the erosion of mountains, and the deterioration of natural landscapes; at the same time, the renewal, renovation, and new construction of urban buildings and municipal facilities have also produced a large amount of construction waste. Most of them are transported to the suburbs or villages without any treatment, and are treated by traditional methods (open-air stacking, landfill, etc.), which not only consumes a lot of cultivated land, but also increases construction costs such as garbage removal and transportation, and also b...
