Description
Technical Field
The invention relates to the technical field of traffic pavement repair, in particular to a rapid repair method for a broken pavement.
Background
The highway is constructed according to the national technical standard and is approved by the highway administration department, and is connected among cities, villages and industrial and mining bases. The highway does not contain a lane naturally formed in the field or in the countryside, is mainly used for driving automobiles and has certain technical standards and facilities. The highway has the difference between a common highway and a special highway for automobiles, the latter is more and more in the highway grade, and the second-level highway has two specifications.
The road surface is easy to break and damage in the long-term use process. The existing way to solve the cracked road surface is:
marking: drawing a marking line around the crack according to the principle of strip repair;
cutting: cutting along the marked line, wherein the depth is not less than 5cm, and the specific depth is determined according to the crack disease condition;
chiseling: chiseling concrete in the joint cutting range by using an air pick, wherein the phenomenon of edge gnawing is avoided during chiseling;
cleaning: cleaning the chiseled concrete, and cleaning the joint cutting vertical surface by using a brush or an iron rag without floating ash;
wetting: fully wetting the cleaned pit surface with clean water, wherein clear water cannot be obtained before repairing, and if the clear water exists, cleaning the water out with a sponge or a mop;
stirring: adding the crack type cement pavement patching material and clean water into a stirrer according to the water cement ratio of 12.5%, stirring for 3-5 minutes until the materials are uniform, then adding 10% -50% of clean broken stone, and continuing stirring until the materials are uniform. (note: the proportion of the aggregate incorporated depends on the depth and width of the chisel, and the aggregate added is smaller at shallower and narrower portions, and has a continuous gradation of less than 30mm in diameter, preferably crushed stone washed with water)
Repairing: pouring the uniformly stirred repair material into a clean repair area, immediately using a scraping ruler to flush, and then using a cleaning cloth to collect light to realize primary forming, wherein the operation practice is controlled within 30 minutes, and secondary surface wiping and press finishing cannot be obtained after primary setting. (if conditional, the repair material is compacted by vibration, but not excessively vibrated)
And (5) maintenance: after finishing the final setting, immediately spraying water to cover for maintenance;
cutting a seam: and cutting a joint of not less than 6cm at the position of the original panel joint or construction joint after 1 hour of final setting, and beating the sealant.
Opening traffic: and after the repair is finished for 24 hours, the isolation is removed, and the traffic is opened. (if the conditions permit, the curing time can be appropriately prolonged).
