1. Project process adjustment
The construction team carefully planned the construction design before the construction, and strictly required the construction according to the project after the engineer's review. In the whole process of project construction, it is necessary to inspect the design and? The implementation of the scheme to ensure the normal implementation of the project construction.
2. Regenerant spraying
The regenerant must be accurately measured and evenly distributed. The spraying of regenerant shall be appropriate to the driving speed of the mixer to ensure the accurate spraying amount per square meter of the old ground. During safe operation, properly check whether the spraying port of regenerant is blocked and whether the spraying is smooth. Monitor the quality of recycled particles anytime and anywhere, adjust the recycled agent timely according to the change of raw materials on the road surface, and ensure that the asphalt aggregate ratio of recycled particles is within the range of adjustment.
3. Milling depth
The milling thickness shall be accurately and evenly distributed, and a special person shall be assigned to inspect the milling depth, inspect it anytime and anywhere, detect that the milling depth deviation is too large, and adjust it in time. The milling depth deviation is 5mm to ensure accuracy as much as possible. It is better not to damage the original joint surface; If the combination of the upper and lower side layers of the original ground is poor and there is a problem of looseness, all the loose layers must be milled and cleaned, and the construction speed of the project shall be moderately slowed down at this time, so as to ensure that there is sufficient temperature at the combination position and ensure the excellent combination of the recycled ground and the original surface layer.
4. Regeneration particle experiment
It is strictly required to conduct sampling test and standard operation according to the items and frequency of the above adjustment standards. Timely sampling test shall be conducted every day, and timely report shall be made to extract the test conclusions to guide the project construction.
