1、混合料佳含水量現(xiàn)場監(jiān)測辦法，一手抓起一把混合料，用力握實，然后松手讓其自由落向地面，正常會立即摔散花，里面沒有小團料。反復試驗，介于落地松散和抱團之間的臨界含水量即佳含水量，一般比試驗單上的佳含水量數(shù)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、作業(yè)施工水罐車停車時一定要離開已施工或待施工水泥已攤鋪路面，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、施工車輛停放時一定要錯開第二天的第一段第一道預工作面，以防止耽誤第二天的人工水泥攤鋪，施工車輛好不要停放在已完成施工的路面上。防治破壞新建結(jié)構(gòu)和影響后期灑水養(yǎng)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“過壓”的錯誤，即過度壓實。若達到材料的大密實度后仍然繼續(xù)碾壓，則會破壞材料，反而降低其密實度。

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、冷再生機的施工作業(yè)應該在每天下午15:00—16:00之間結(jié)束，以便后續(xù)施工能在天黑前結(jié)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、每天冷再生租賃機結(jié)束施工進行洗刀停車后，應通知操作手仔細檢查車況并更換刀頭，以免耽誤第二天的施工進度。

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.
