路面铣刨 ：

　　Road milling:

　　将旧沥青混凝土路面面层（9cm）全部铣刨掉，并在一侧存放。

　　Mill off all 9cm of the old asphalt concrete pavement surface layer and store it on one side.

　　铣刨石灰、粉煤灰、碎石基层（18cm），并在另一侧存放，同时进行配比试验以确定水泥添加量。

　　Milling lime, fly ash, and crushed stone base (18cm) and storing them on the other side, while conducting proportioning tests to determine the amount of cement added.

　　刨松灰土基层 ：

　　Loosening the lime soil base layer:

　　刨松西侧灰土基层（25cm），确保压实度大于95%。

　　Loosen the lime soil base layer on the west side (25cm) to ensure a compaction degree greater than 95%.

　　冷再生骨料回填与拌和 ：

　　Cold recycled aggregate backfilling and mixing:

　　将东侧冷再生骨料向西侧回填，并进行机械找平和轻型碾压。

　　Backfill the cold recycled aggregate from the east side to the west side, and perform mechanical leveling and light rolling.

　　摊铺4%-5%的水泥，进行第一部冷再生，控制厚度为25cm。

　　Spread 4% -5% cement and carry out the first cold regeneration, with a controlled thickness of 25cm.

　　洒水养生 ：

　　Watering for health preservation:

　　对冷再生基层洒水养生，达到7天龄期后，将东侧剩余骨料均匀摊铺在冷再生基层上，并进行冷再生（18cm），洒水养护不少于28天。

　　Spray water on the cold recycled base for curing. After reaching a 7-day age, evenly spread the remaining aggregate on the east side on the cold recycled base and perform cold recycling (18cm). Spray water for curing for no less than 28 days.

　　第二阶段冷再生 ：

　　Second stage cold regeneration:

　　西侧车道第一部冷再生达28天龄期后，依据试验配比添加碎石，并整平进行轻型碾压，摊铺4%-5%的水泥，进行第二部冷再生，控制厚度为20cm，洒水养护28天。

　　After the first section of the west lane has been cold recycled for 28 days, crushed stones are added according to the experimental ratio, leveled and lightly compacted, and 4% -5% cement is spread for the second section of cold recycling, with a controlled thickness of 20cm. Watering and curing are carried out for 28 days.

　　面层施工 ：

　　Surface layer construction:

　　西侧车道第二部冷再生达28天龄期后，主路洒布乳化沥青水封层（厚度1cm），机械摊铺粗粒式沥青砼（AC-25）6cm和中粒式沥青砼（AC-16）4cm。

　　After the second section of the west lane has reached 28 days of cold recycling, the main road is sprayed with emulsified asphalt water seal layer (thickness 1cm), and mechanically paved with coarse asphalt concrete (AC-25) 6cm and medium asphalt concrete (AC-16) 4cm.

　　清理现场并开放交通 ：

　　Clean up the site and open up traffic:

　　最后清理现场，确保道路表面整洁，然后开放交通。

　　Finally, clean up the site to ensure the road surface is clean, and then open up traffic.

　　建议

　　proposal

　　在施工过程中，应严格控制冷再生层的厚度和压实度，确保达到设计要求。

　　During the construction process, the thickness and compaction of the cold recycling layer should be strictly controlled to ensure that the design requirements are met.

　　定期检测水泥和骨料的添加量，以及混合料的含水量，确保冷再生层的强度和稳定性。

　　Regularly check the amount of cement and aggregate added, as well as the moisture content of the mixture, to ensure the strength and stability of the cold recycled layer.

　　严格按照施工工艺流程进行操作，避免因质量问题影响道路的使用寿命和安全性。

　　Strictly follow the construction process to avoid affecting the service life and safety of the road due to quality issues.
