What are the basic requirements of cement stabilized gravel base?
(1) For gravels, solid and clean granular materials shall be selected according to the transportation location of the materials.

(2) The dosage of cement should be accurately controlled according to the design requirements. When mixing, it must be dry mixed evenly first, and then wet mixed with water until the color of the mixture is consistent.

(3) In the process of watering and mixing, the water consumption is slightly greater than the optimal water content to compensate for the evaporation of water during construction.

(4) Under the condition that the mixture is at the optimum water content, it will be rolled by a heavy roller to the required degree of compaction, and the compaction thickness of each layer shall not exceed 15cm.

(5) During the construction of cement stabilized macadam, it is advisable to adopt sectional flow operation, and the time from adding water to the end of rolling should not exceed 4 hours.

(6) After passing the rolling inspection, immediately cover or spray water for curing, and the curing period is generally not less than 7 days.

(7) The original construction records are complete.
