沥青路面冷再生机施工需要注意的事项

来源:http://www.tclqgc.com/ 日期:2024-01-25 发布人:

1、将铣刨料运送回料场后,依据持续循环系统粉碎筛分。回收料应尽量减少在高温和重力作用 下使材料再次粘接一起,需注意推料高度,注意防水。

1. After transporting the milling and planing materials back to the material yard, they are crushed and screened according to the continuous circulation system. Recycled materials should be minimized from being re bonded under high temperature and gravity, and attention should be paid to the pushing height and waterproofing.

2、乳化沥青冷再生混合料的搅拌时间应短于热拌沥青混合料的搅拌时间。若过多搅拌,则粗集 料表层的乳化沥青容易脱落下来,且可造成乳化沥青提早破乳,使再造混合料的施工和易性变 差;而搅拌不充足,则造成集料无法被乳化沥青充足裹附。

2. The mixing time of emulsified asphalt cold recycled mixture should be shorter than that of hot mix asphalt mixture. If too much mixing is done, the emulsified asphalt on the surface of the coarse aggregate is prone to fall off, and it can cause premature emulsification of the emulsified asphalt, resulting in poor construction and workability of the recycled mixture; If the mixing is not sufficient, it will cause the aggregate to not be fully coated with emulsified asphalt.

3、夏天施工时,因为乳化沥青迅速破乳,为此再造混合料通常不适合远距离运送,拌合厂宜设 置在相距当场周围很近的地区。雨期时,宜选用合理对策避免集料水分含量增多,同时应依据 集料和再造混合料水分含量的大小及时性调节拌合机中的加水量。

3. During summer construction, due to the rapid emulsification of emulsified asphalt, the reconstituted mixture is usually not suitable for long-distance transportation. The mixing plant should be located in an area very close to the site. During rainy season, it is advisable to choose reasonable measures to avoid an increase in moisture content in the aggregate. At the same time, the amount of water added to the mixer should be adjusted in a timely manner based on the moisture content of the aggregate and recycled mixture.

4、沥青摊铺机的熨平板无须预热,以避免再造混合料中水份散失过快而影响其和易性。

4. The ironing plate of the asphalt paver does not need to be preheated to avoid rapid water loss in the recycled mixture and affecting its workability.

5、辗压宜选用12吨双钢轮静压1-2遍,随后震动辗压1-2遍。复压选用大吨位(26吨及以上)碾 压。辗压时可喷少许的雾水。辗压以无显著轮迹且水膜匀称分布为宜,

5. It is recommended to use 12 ton double steel wheels for static pressure 1-2 times, followed by vibration rolling 1-2 times. Heavy tonnage (26 tons and above) is selected for re compaction. Spray a little mist when rolling. Rolling should be carried out with no significant wheel marks and a uniform distribution of water film,

6、辗压机会相当关键,应在施工过程中监测。当再造混合料中的乳化沥青开始破乳时,变 可开展辗压。

6. The rolling opportunity is crucial and should be closely monitored during the construction process. When the emulsified asphalt in the recycled mixture begins to break, rolling can be carried out.
