1、混合料佳含水量现场监测办法，一手抓起一把混合料，用力握实，然后松手让其自由落向地面，正常会立即摔散花，里面没有小团料。反复试验，介于落地松散和抱团之间的临界含水量即佳含水量，一般比试验单上的佳含水量数值多1%-2%。

1. The on-site monitoring method for the optimal moisture content of the mixture is to grab a handful of the mixture with one hand, firmly grip it, and then release the hand to let it fall freely to the ground. Normally, it will immediately scatter flowers without any small lumps inside. Repeated experiments have shown that the critical moisture content between loose ground and clumping is the optimal moisture content, which is generally 1% -2% higher than the optimal moisture content value on the test sheet.

2、作业施工水罐车停车时一定要离开已施工或待施工水泥已摊铺路面，以防止漏水引起的局部水大。

2. When parking the construction water tank truck, it is necessary to leave the road surface that has already been constructed or the cement has been paved to prevent local water leakage.

3、施工车辆停放时一定要错开第二天的第一段第一道预工作面，以防止耽误第二天的人工水泥摊铺，施工车辆好不要停放在已完成施工的路面上。防治破坏新建结构和影响后期洒水养生。

3. When parking construction vehicles, it is necessary to stagger the first section of the first pre working surface of the next day to prevent delaying the manual cement paving of the next day. Construction vehicles should not be parked on the completed road surface. Prevention and control of damage to new structures and impact on later watering and health preservation.

4、避免犯“过压”的错误，即过度压实。若达到材料的大密实度后仍然继续碾压，则会破坏材料，反而降低其密实度。

4. Avoid making the mistake of "over compaction", that is, over compaction. If the material continues to be compacted after reaching its high density, it will damage the material and instead reduce its density.

5、冷再生机的施工作业应该在每天下午15:00—16:00之间结束，以便后续施工能在天黑前结束。

5. The construction work of the cold regeneration machine should end between 15:00 and 16:00 every afternoon, so that subsequent construction can be completed before dark.

6、每天冷再生租赁机结束施工进行洗刀停车后，应通知操作手仔细检查车况并更换刀头，以免耽误第二天的施工进度。

6. After the construction of the cold regeneration rental machine is completed and the knife is washed and stopped every day, the operator should be notified to carefully inspect the condition of the vehicle and replace the knife head to avoid delaying the construction progress of the next day.
