According to Aiwen Education Network, the difference between lime fly ash and water stability lies in different components and different uses. The fly ash is fly ash and lime, and the water stability is cement stabilized macadam or stone chips. The water-stabilized cutting structure with a certain bending load is widely used, mainly as the base. Water-stabilized layer is the abbreviation of cement stabilized macadam layer, that is, cement solidified graded macadam is completed by compaction and maintenance. The water-stable mixture ratio should be mixed in the laboratory in advance to determine the cement content and the proportion of coarse and fine aggregate, and at the same time determine the maximum dry density. A large amount can be mixed in a water-stable mixing station.
