Embodiment 1
[0029]The composite admixture of domestic waste incineration fly ash is used as a stabilizing material to prepare a cement / incineration fly ash stabilized crushed stone mixture according to the following methods:
[0030] First, the water content does not exceed 5%, the strength activity index is 54.7%, and the solid content is 7kg of domestic waste incineration fly ash, 3kg of active mixed material (slag powder), 0.1kg of activator (sodium silicate) Carry out dry powder mixing, and form a composite admixture after mixing evenly;
[0031] Then, the composite admixture was added to the C-B-3 graded crushed stone ore containing 40.4kg of solid content and mixed evenly, then water was added to mix the material and the material was sealed for 12h;
[0032] Finally, cement with a solid content of 0.95kg (42.5 grade ordinary Portland cement) was added, and then water was added, and the mixture was uniformly mixed to form a cement / incineration fly ash stabilized crushed stone mixture...
Embodiment 2
[0035] The composite admixture of domestic waste incineration fly ash is used as a stabilizing material to prepare a cement / incineration fly ash stabilized crushed stone mixture according to the following methods:
[0036] First, the water content does not exceed 5%, the strength activity index is 54.7%, and the solid content is 7kg of domestic waste incineration fly ash, 6kg of active mixed material (fly ash), and 0.1kg of activator (alum). The dry powder is mixed, and the compound admixture is formed after mixing evenly;
[0037] Then, the composite admixture was added to the C-B-3 graded crushed stone ore containing 26.2kg of solid content and mixed evenly, and then water was added to mix and seal the material for 18h;
[0038] Finally, cement (42.5 grade ordinary Portland cement) with a solid content of 1.0 kg is added, and then water is added, and the mixture is uniformly mixed to form a cement / incineration fly ash stabilized crushed stone mixture.

Embodiment 3
[0041] The composite admixture of domestic waste incineration fly ash is used as a stabilizing material to prepare a cement / incineration fly ash stabilized crushed stone mixture according to the following methods:
[0042] First, dry powder of 4kg of domestic waste incineration fly ash with solid content of 4kg and 3kg of active mixed material (slag powder) and 0.3kg of activator (alum) with a water content of no more than 5% and a strength activity index of 54.7%. Mix, and form a composite admixture after mixing evenly;
[0043] Then, the composite admixture was added to the C-B-3 graded crushed stone ore containing 36.5kg of solid content and mixed evenly, and then water was added to mix and seal the material for 16h;
[0044] Finally, cement (42.5 grade ordinary Portland cement) with a solid content of 1.62 kg was added, and then water was added, and the mixture was uniformly mixed to form a cement / incineration fly ash stabilized crushed stone mixture.
