The requirement of construction specification is that the next step of construction can only be carried out after 7 days of curing, and the strength requirement of water-stable materials is also defined according to 7 days (7 days unconfined compressive strength). Long curing time is no problem, and high temperature in water temperature materials is beneficial to the growth of cement strength. As long as water-stable materials are formed, long-term curing will not affect the strength.

Stable layer is the abbreviation of cement stabilized macadam layer, that is, cement consolidated 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.
