Description
Technical field
The utility model relates to a kind of regenerating mixture for the cold regeneration of sheet pavement in-situ, heat regeneration construction and gathers materials on the spot and stir the construction operation special equipment that paves, and belongs to sheet pavement in-situ regeneration construction equipment technical field.
Background technology
Flexible pavement is under the effect of traffic load and climatic effect, and As time goes on, pavement behavior and service ability will run down.Particularly High Grade Bitumen Pavement is due in long-term use procedure, exist because of time, daylight, air, temperature particularly long-term motor vehicle to roll the asphalt performance caused in regenerating mixture aging, there will be such as the hole groove, gather around the dissimilar diseases such as bag, be full of cracks, purt slurry, rut, crackle.For the functional performance that keeps flexible pavement with extend its application life, in each different phase of life cycle, need to adopt different maintenance measures, in order to keep the service ability on road surface, in the life-extending cycle, improve the pollution to surrounding enviroment such as noise, vibration.For or be about to enter maintenance interval disease road surface, traditional method is by the compound on the milling old asphalt pavement, then again overlays virgin material, can make thus a large amount of to dig, the milling compound goes out of use, causing environment pollution on the one hand, is the significant wastage of resource on the other hand.And apply old compound Regeneration and Repair road surface, former road surface a kind of brand-new asphalt pavement conserving construction technology just.From people, begin one's study the application Applied of Asphalt Pavement Recycle Technique, just propose cold regeneration and two kinds of different concepts of heat regeneration.
While using the Bituminous Pavement Cold Regeneration construction technology, ordinary circumstance is, by a cold regenerative machine milling and planing drum, milling, fragmentation are carried out in former road surface, simultaneously the road surface compound after new aggregate, additive and the fragmentation added is mixed and stirred and is in the same place.Although in work progress, be in the driving process be at a slow speed, but the motion process on a milling milling road surface still completes within the extremely short time, the aggregate newly added, additive and can't be realized stirring uniformly purpose by road surface compound after milling, the regeneration effect of the old pavement regenerating mixture therefore reached can not reach desirable requirement, especially the compound uniformity in road surface does not reach technical requirements, causes the very difficult assurances of construction quality such as surface evenness.
Equally when carrying out the asphalt surface hot reproduction construction technology, at first by the heating car, old asphalt pavement is heated, harrows pine, by the new mixing of compound waggon interpolation, expected and needed the flexible pavement of regenerating again, and by the asphalt surface hot reproduction car, new, old regenerating mixture is gathered materials, and rising to stirring in remixer, the compacting that finally paves forms new flexible pavement.This process is combined and has been constructed by multiple devices, works continuously and just can complete as asphalt surface hot reproduction car (effect of gathering materials), the equipment such as remixer (effect of mixing and stirring) and paver that promote.Just because of the construction that needs multiple devices, can cause construction length to increase, the regenerated road surface quality can be affected.For solve in above-mentioned described cold regeneration technology construction that the milling process can't stir and need to be by the asphalt surface hot reproduction car during construction of hot regeneration technology, promote the technical barrier that the multiple devices such as remixer and paver be combined use, proposes a kind of be applicable to that the cold regeneration of sheet pavement in-situ or heat regeneration constructs integrate pavement breaking, the special equipment of the construction operation that gathers materials, stirs, paves.
