Lime stabilized soil base construction:

(1) Control the thickness of virtual paving, ensure the thickness and elevation of base course, and ensure that the transverse slope of road arch is consistent with the requirements of surface course.

(2) When rolling, the compaction thickness should be adapted to the rolling machinery, and the water content should be within the allowable deviation range of the optimal water content to meet the requirements of compaction degree.

(3) It is forbidden to use thin-layer patching for leveling.

(4) Lime soil should be kept moist, and the curing period should not be less than 7d. Traffic should be closed during maintenance.

Option A, the road arch transverse slope of the whole base should meet the requirements of the surface layer. Option b, it is forbidden to use thin-layer patch for leveling. Option d, from mixing to paving, shall not exceed 3h. Which belongs to the construction requirements of cement stabilized soil base.
