The requirement of the construction specification is that the next step of construction can only be carried out after 7 days of curing, and the strength of water-stable materials is also defined according to 7 days. If the curing time is a little longer, the influence is not great, and high temperature is beneficial to the increase of cement strength in water-stabilized materials. As long as the water-stable material is molded, its strength will not be affected after a long curing time. However, if the curing time is short, the strength of the water-stable layer will be greatly reduced.

Water stabilization method: Water stabilization is the abbreviation of cement stabilized macadam, that is, cement consolidated graded macadam is completed by compaction and maintenance. The water-stable mixture ratio should be tested in the laboratory in advance to determine the cement content and the proportion of coarse and fine aggregate, and determine the maximum dry density.
