冷再生机对于施工质量有什么要求?你知道吗?
What is the requirement for construction quality? You know what?
1、乳化沥青再生与泡沫沥青再生压实度
1, emulsified asphalt regeneration and foam asphalt regeneration compaction degree
高速公路与一级公路的乳化沥青再生压实度需要达到90%以上,泡沫沥青再生压实度需要达到98%以上;二级及二级以下公路,乳化沥青再生压实度需达到88%以上,泡沫沥青再生压实度需要达到97%以上。每车道每检查两次。
The compactness of emulsified asphalt for Expressway and first grade highway needs to reach more than 90%, and the degree of regeneration and compactness of foam asphalt needs to reach more than 98%. After two and two grade, the compactness of emulsified asphalt should reach 88%, and the degree of regeneration and compaction of foam asphalt needs to reach 97%. Check twice per lane and every kilometer.
2、含水率
2. Moisture content
冷再生机施工含水率需要符合基本规范要求,每三个工作日检验一次。
The construction moisture content of the cold recycling machine should meet the requirements of the basic specifications, and should be inspected every three working days.
3、沥青含量矿料级配
3. Asphalt content mineral aggregate gradation
发现沥青含量矿料级配异常时应随时检验,检验方法为油提筛分。
When the asphalt content mineral aggregate gradation is abnormal, it should be inspected at any time, and the inspection method is oil extraction and screening.
4、冻融劈裂强度比
4. Freeze thaw splitting strength ratio
冻融劈裂强度比应大于70%,每三个工作日检查一次。
The ratio of freeze-thaw splitting strength should be greater than 70%, and it should be checked every three working days.
5、其他检查项目
5. Other inspection items
残留稳定度,干湿劈裂强度比,马歇尔稳定度,15℃劈裂强度等,需要每工作日检查一次,符合设计要求。
The residual stability, dry wet splitting strength ratio, Marshall stability, 15 ℃ splitting strength, etc. need to be checked every working day, which meets the design requirements.
冷再生机的熟练操作可以很大的提高工作效率,能够缩短工期,有着很大的作用。
The skilled operation of cold regenerator can greatly improve the work efficiency and shorten the construction period.
1、使用后控制台时,需将开关拨到后控制,此时前控制台无作用,此外各个小喷头开关可以使用后控制台打开、关闭。
1. When using the rear console, turn the switch to the rear control. At this time, the front console does not work. In addition, each small nozzle switch can be opened and closed by using the rear console.
2、乳化沥青设备不能灌的太满,加油口盖必须关紧,运输过程中以防沥青溢出。
2. The emulsified asphalt equipment cannot be filled too full, and the filler cap must be closed tightly to prevent asphalt overflow during transportation.
3、乳化沥青设备在喷洒前一定要检查各阀门位置是否正确。加入乳化沥青设备内的热态沥青必须达到160~180℃的工作温度,长距离运输或工作时间过长,可使用加温装置保温,但不能当作熔油炉。
3. Before spraying, the emulsified asphalt equipment must check whether the valve position is correct. The hot asphalt added into the emulsified asphalt equipment must reach the working temperature of 160 ~ 180 ℃. If the asphalt is transported for a long distance or the working time is too long, the heating device can be used for heat preservation, but it can not be used as an oil melting furnace.
以上是有关冷再生机对施工质量的要求的相关介绍,希望能对大家有所帮助。
The above is about the cold recycling machine on the construction quality requirements of the relevant introduction, I hope to help you.
