The road surface of the cold regeneration zone of this bilayer has good way and uses the performance, after adopting this road surface structure to restore, can make the bearing capacity on former road surface obtain recovering or improving, and to there being the old material in road surface to obtain maximum regeneration, its utilization ratio can reach 80%~95%, very big reduction to the demand of new building stones and pitch, 80% the heating energy has also been practiced thrift for tradition maintenance mode, reduce that 80% sulfur dioxide discharges and about 15%~20% engineering maintenance fund.
Description
Technical field
This utility model belongs to pavement maintenance & rehabilitation field, is specifically related to a kind of road surface based on double-deck cold renewal layer.
Background technology
The high-grade highway that China builds in early days has progressed into overhaul time, and overhauling of road surface creates a large amount of waste and old construction material, and this not only wastes resource but also environment is created pollution.Therefore the rational regeneration old material of former road-surface milling is the task that road maintenance technical field is the most urgent.Traditional hot-mix asphalt mixture is relatively costly, and rubble and consumption of asphalt are very big, and serious waste of resources and generation large quantity of exhaust gas during road surfacing pollute environment.Therefore Bituminous Pavement Cold Regeneration technology is more and more paid attention to.
Bituminous Pavement Cold Regeneration technology can be constructed under normal temperature condition, this construction technology can not only utilize the obsolete material of old pavement, save road-making material, also solve obsolete material to appropriation of land and the pollution to environment, have that embodiment is easy, save the advantages such as duration simultaneously.Therefore, cold recycling technology can be reduced investment outlay, it is thus achieved that directly economic benefit, also can obtain preferable social benefit, be an environment-friendly type new technique benefited the nation and the people.
Bituminous paving is when using cold recycling technology to keep in repair at present, generally only carry out the monolayer cold renewal punishment of limited thickness, or mixed regeneration cement stabilized macadam base and surface layer old asphalt, but the characteristic due to this bi-material, the material of mixed regeneration has been short of in uniformity with in terms of intensity, uses monolayer regeneration then can there is the punishment of former pavement disease the most thorough.As used double-deck cold-regenerated road surface structure then road pavement structure can do overall Regeneration and Repair punishment, then can recover or improve the bearing capacity on former road surface greatly.
Utility model content
The utility model proposes the road surface of a kind of double-deck cold renewal layer, this road surface has good pavement performance, uses the road surface after this structure repair, and bearing capacity can be restored or improve.
The technical solution of the utility model is achieved in that a kind of road surface based on double-deck cold renewal layer, including former road surface residual structural layer, cement it is provided with on the spot or cold in-plant recycling layer on the residual structural layer of described former road surface, described cement on the spot or is equipped with Foamed Asphalt cold renewal layer on cold in-plant recycling layer, described Foamed Asphalt cold renewal layer is also equipped with water-proof tack coat, it is equipped with the Sub-course Asphalt Concrete on described water-proof tack coat, described the Sub-course Asphalt Concrete is equipped with modified asphalt concrete upper layer
Further, cement is on the spot or the thickness of cold in-plant recycling layer is 18～25cm.
Further, the thickness of Foamed Asphalt cold renewal layer is 10～15cm.
Further, the thickness of described the Sub-course Asphalt Concrete and modified asphalt concrete upper layer is 9～10cm.
The beneficial effects of the utility model are as follows: the road surface of this bilayer cold renewal layer has good pavement performance, after using this pavement structure to repair, owing to having Cement Cold Regeneration Technology basic unit and foamed asphalt cold renewal layer, so the bearing capacity on former road surface can be made to be restored or improve, and material old to existing road surface has obtained maximum regeneration, its utilization rate is up to 80%～95%, greatly reduce the demand to new building stones and Colophonium, also the heating energy source of about 80% has been saved relative to traditional maintenance mode, reduce the maintenance of works fund of 80% sulfur dioxide (SO2) emissions and about 15%～20%.
