整形
plastic
（1）混合料拌和平均后，应立刻用平地机初步整形。在直线段，平地机由两侧向路中心停止刮平；在平曲线段，平地机由内侧向外侧停止刮平。
(1) After the mixture is evenly mixed, it shall be preliminarily shaped with a Grader immediately. In the straight section, the Grader stops scraping from both sides to the road center; In the flat curve section, the Grader stops scraping from the inside to the outside.
（2）用轮胎压路机立刻在初平的路段上快速碾压一遍，以暴露潜在的不平整。
(2) Immediately use a tire roller to quickly roll over the initially flat road section to expose potential unevenness.
（3）再用平地机按本条第1款停止整形，整形前应用齿耙将轮迹低洼处表层5cm以上耙松，并按本条第2款再碾压一遍。
(3) Then use the Grader to stop shaping according to paragraph 1 of this article. Before shaping, use the tooth harrow to loosen the surface of the low-lying part of the wheel track for more than 5cm, and roll it again according to paragraph 2 of this article.
碾压
Rolling
（1）整形后，当混合料的含水量为佳含水量（+1%~+2%）时，应立刻用压路机在构造层全宽内停止碾压。直线和不设超高的平曲线段，由两侧路肩向路中心碾时，应堆叠1/2轮宽，后轮必需超越两段的接缝处，后轮压完路面全宽时，即为一遍。普通需碾压4~6遍。
(1) After shaping, when the moisture content of the mixture reaches the optimal moisture content (+1%~+2%), the roller should immediately stop rolling within the full width of the construction layer. When rolling straight and flat curved sections without superelevation from the shoulders on both sides to the center of the road, they should be stacked with a width of 1/2 of the wheel width. The rear wheel must exceed the joint of the two sections. When the rear wheel has pressed the full width of the road surface, it is considered as one pass. Normally, it needs to be rolled 4-6 times.
（2）严禁压路机在已完成的或正在碾压的路段上调头或急刹车，应保证改进土层外表不受毁坏。
(2) It is strictly prohibited for road rollers to turn around or brake sharply on completed or rolling sections, and it is necessary to ensure that the surface of the improved soil layer is not damaged.
（3）碾压过程中，水泥改进土的外表应一直坚持潮湿，如水分蒸发过快，应及时补撒少量的水，但严禁洒大水碾压。
(3) During the rolling process, the surface of cement modified soil should always be moist. If the water evaporates too quickly, a small amount of water should be sprinkled in a timely manner, but it is strictly prohibited to sprinkle large amounts of water for rolling.
（4）冷再生机租赁人员认为，经过拌和、整形的水泥改进土，宜在水泥初凝前并应在实验肯定的延迟时间内完成碾压，并到达请求的密实度，同时没有明显的轮迹。
(4) The leasing personnel of the cold recycling machine believe that the cement improved soil after mixing and shaping should be compacted before the initial setting of the cement and within the confirmed delay time in the experiment, and reach the requested compactness without obvious wheel marks.
（5）在碾压完毕之前，用平地机再终平一次，使其纵向顺适，路拱和超高契合设计请求。终平应认真停止，必需将部分高出局部刮除并扫出路外；关于部分低洼之处，不再停止找补，可留待下层施工时处置。
(5) Before the completion of rolling, use a Grader for final leveling again to make it longitudinally smooth, and the crown and superelevation meet the design requirements. The final leveling should be stopped seriously, and it is necessary to scrape off the parts that are higher than the original ones and sweep them out; Regarding some low-lying areas, repair will no longer be stopped and can be left for disposal during lower level construction.
