Cement stabilized macadam mixture and road base layer construction method used in high-temperature seasons

Abstract

The invention discloses a cement stabilized macadam mixture and a road base layer construction method used in high-temperature seasons. The mixture comprises cement, a saccharose solution, stabilizedmacadam rough aggregates and fine aggregates. Saccharose is fused in cement stabilized macadam mixed water, the cement hydration reaction can be delayed, the non-delayed-coagulation cement delayed coagulation effect is achieved, and the cement stabilized macadam mixture has sufficient construction delay time. The construction delay time can be flexibly adjusted according to the mixing amount, thesufficient construction time can be achieved for the cement stabilized macadam mixture under the situation that ordinary cement is used in the scorching summer, and accordingly the engineering qualityis ensured.

Description

technical field

[0001] The invention belongs to road engineering, in particular to a road base construction method. Background technique

[0002] In road engineering construction, cement-stabilized macadam is a relatively common material structure as the base layer, and it is widely used in various places. However, with the adjustment of the production capacity of the cement industry, the slow-setting cement specially used for roads is no longer produced in many areas due to its small application range, forcing the road base construction in some areas to use conventional building structure cement, and the setting time of this cement It is very short, usually 1.5 to 2 hours, which cannot meet the demand of 2 to 3 hours for the delay time of road base construction, which affects the quality of base construction.

[0003] Due to the limited construction period, the construction of the road base is inevitable in high temperature seasons. In high temperature seasons, the effecti...
