a. Inspection and acceptance during road mixing, cleaning and clearing the lower bearing layer to check the compaction, flatness, elevation, cross slope, plane size, etc. of the soil foundation must be rolled with a 12-15T roller or equivalent roller. (3-4 times) If the surface is loose, springs and other phenomena must be treated.

B. Construction stakeout: restore the centerline of the road, release the sideline piles, and then level them, and accurately mark the top level of the implementation on the side piles.

C. Pave the shoulders and compact.

D. Prepare sufficient quality raw materials according to the construction mix ratio.

E. Do the test section well to determine the construction process, the length of the construction section, the loosening factor, the number of personnel, machinery, and the number of compaction passes to guide normal construction.

F. Calculate the quantity of materials, and calculate the distance of each material according to the thickness, width, stable soil density, wet bulk density of the soil and the tonnage of the material carrier used. Use plum-shaped cloth.

G. Use bulldozer and grader to spread and level. According to the loose paving coefficient, the cross slope of the road arch, the line can be controlled to control the paving elevation, and supplementary and stabilized. At the same time, the water content of the mixture should be measured, so that the water content of the mixture after road mixing is slightly higher than 1-2% of the optimal water content, otherwise the sprinkler will be used.

H. Calculate the paving area of each pack of cement according to the mix ratio, draw a grid of artificial ash, or use a machine (ash spreader) to evenly spread the cement on the treatment surface according to the design amount.

I. Stabilize the soil mixer with motorized harrow, multi-plow plough and other machinery to mix the mixture and dig the pit to make the mixture a homogeneous mixture with uniform color and no gray bars, ash masses and flower surface. During the mixing process, the water content should be checked at any time. If the water content is insufficient, it should be supplemented with water and wet.

j. After the mixture is evenly mixed, immediately use the grader to initially level the shape. Use a tractor, grader, or tire roller to quickly roll it 1-2 times to expose the potential unevenness, and then pull the wire to make a cross section of three elevations every 10m, and use Wooden piles, bricks, and white ash are clearly marked, and the grader cooperates with the human to perform leveling in order and check the elevation at any time.

K. Rolling should be carried out immediately after flattening, the rubber wheel first, then the light wheel, first light, then heavy, then light. If it is coarse, you can use the method of light weight, then vibration, and then the smooth surface of the rubber wheel.

L. Leave about 2-3m of loose material at the end of the working section and re-mix the ash during the construction of the next section, level it, and roll it to make the joints smooth and dense. After the road section is formed, it should be sprinkled with water in time to maintain health, and the surface of the mixture should be kept moist for seven days. It is not recommended to open the traffic without the upper bearing layer.

m. Cement stabilized soil should strictly control its survival time. In addition to low-grade cement with a long initial setting time, it should also be appropriate in section length. Road mixer construction must be compact. In short, it must not exceed 3 from mixing to rolling. -4 hours.

N. Internal self-inspection shall be performed on the formed cement stabilized soil base course.
