人工撒布水泥的施工方法：

　　Construction method of manually spreading cement:

　　⑴、水泥用量计算：老路段水泥稳定碎石冷再生设计剂量为5%，密度：2.137 g/cm3   厚度：0.25m 每平米水泥用量：0.25*2.137*0.05*1000=26.7125斤。加宽段水泥稳定碎石水泥剂量6%。密度：2.086 g/cm3 厚度0.15m 每平米水泥用量：0.15*2.086*0.06*1000=18.774公斤。

　　⑴ Calculation of cement dosage: The design dosage for cold recycling of cement stabilized crushed stone in the old road section is 5%, with a density of 2.137 g/cm3 and a thickness of 0.25m. The cement dosage per square meter is 0.25 * 2.137 * 0.05 * 1000=26.7125 pounds. The cement dosage for stabilizing crushed stone in the widened section is 6%. Density: 2.086 g/cm3 Thickness: 0.15m Cement dosage per square meter: 0.15 * 2.086 * 0.06 * 1000=18.774 kilograms.

　　⑵、打布水泥方格：半幅宽度为7.2m+4.58m=11.58m。纵向可分2.4*3+2.3*2划分，根据每平米水泥用量，老路5%水泥用量布控长度：100/26.7125/2.4=1.56m  即老路5%水泥用量布控为2.4*1.56；老路4.5%水泥用量布控长度：100/24.04125/2.4=1.73m  即老路4.5%水泥用量布控为2.4*1.73；加宽段布控长度:100/18.774/2.3=2.32m；即布控为2.3*2.32。

　　⑵ Laying cement grid: half width of 7.2m+4.58m=11.58m. Vertically, it can be divided into 2.4 * 3+2.3 * 2 sections. According to the cement consumption per square meter, the length of the old road's 5% cement consumption control is 100/26.7125/2.4=1.56m, which means the old road's 5% cement consumption control is 2.4 * 1.56; The length of the 4.5% cement consumption control for the old road is 100/24.04125/2.4=1.73m, which means that the 4.5% cement consumption control for the old road is 2.4 * 1.73; Widening section control length: 100/18.774/2.3=2.32m; that is, the control length is 2.3 * 2.32.

　　⑶、摊铺水泥：每个方格放足量合格的水泥两袋，人工拆开封口，用推板刮匀。布水泥段落长度和冷再生铣刨机速度速度相适应，一般在冷再生前60-80m，过长水泥将被风、或行车产生的气流刮走而造成损失。

　　⑶ Laying cement: Place two bags of qualified cement in each square, manually open the seal, and use a push plate to scrape evenly. The length of the cement section is adapted to the speed of the cold recycling milling machine, usually 60-80m before cold recycling. If the cement is too long, it will be blown away by the wind or the airflow generated by the vehicle, causing losses.

　　粉料撒布车的施工方法：

　　Construction method of powder spreading vehicle:

　　⑴、水泥运输车压力输入撒布车进行装料。

　　⑴ The pressure input of the cement transport vehicle is used to load the material into the spreading vehicle.

　　⑵、设定撒布水泥的宽度和厚度。

　　⑵ Set the width and thickness for spreading cement.

　　⑶、进行全自动均匀撒布。

　　⑶ Perform fully automatic and uniform spreading.
