Description

Road surface hot recycling machine and road surface hot reproduction construction method

Technical field

The invention belongs to pavement recycling technical field, particularly relate to a kind of road surface hot recycling equipment and pavement recycling construction party Method.

Background technology

Along with the high speed development of Chinese national economy, highway in China construction achieves the development of great-leap-forward.Great development is in early days The road come into operation, has subsequently entered the maintenance phase the most, and maintenance amount is in line ascendant trend.Highway pavement, especially It is that the various functions of surface of bituminous paving decay quickly after a long time use, directly influences the driving safety of automobile and relaxes Adaptive, this is accomplished by road pavement and repairs.Past people use milling machine by after old pavement milling, re-lay new asphalt road Face.But a large amount of discarded waste materials after road-surface milling, can be produced, these waste materials or transported are abandoned, or transport to special Process place and carry out broken recycling, the most not only pollute environment, also expend significant cost simultaneously.

Begin one's study pavement recycling technology for these people, it is desirable to find low cost and environment protection pavement maintenance technology.Due to old Asphalt material is a kind of material resources that can carry out Design for Regeneration and utilization, completely can be with regeneration, therefore bituminous paving Regeneration techniques is the study hotspot in maintenance of surface field in recent years.Asphalt surface hot reproduction technology carries out layering by road pavement and adds Heat, layering milling, regeneration pave, it is achieved the reparation on road surface, it maximally utilises waste and old compound, is done directly road on the spot Face is repaired, and not only saves substantial amounts of sand material and Colophonium resource, and has effectively prevented mining and excavated discarded old material And take a large amount of land resource.

Applied of Asphalt Pavement Recycle Technique includes cold renewal and hot recycling.Cold renewal uses high-power road-surface milling mixer by road The milling on the spot on former road surface of face compound, dig, broken, add stabilizer, cement, water (or emulsified asphalt) and aggregate together Time mix-in-place, last roller-compaction.Cold renewal is low for equipment requirements, and production cost is the highest, but regenerated road surface quality is not very Good, it is not suitable for the reparation of high grade pavement.

Hot recycling passes through thermoplastic road surface, scoops up road surface waste material, then mixes with bituminous cement, or is simultaneously introduced new Aggregate, is finally layered on original road surface again by reworked material.Existing road surface hot recycling generally uses Unit erriger, first by Colophonium After thermal softening is baked on road surface, Bituminous concrete surface layer is collected and is transported in blender, add new aggregate, supplement new Colophonium, after stirring Utilize spreader to carry out paving, consolidate, press, then carry out rolling and form new road surface.Owing to hot in-place recycling can preserve bone That expects is intact, retains composition and the performance of Colophonium, and Pavement Performance is more preferable, and old material 100% recycles, more energy efficient environmental protection.

But in the hot recycling technique of existing road surface, be all first bottom surface is heated after, then milling or rake pine, then receive Collect old material, in traditional handicraft during heated asphalt concrete road surface, the problem that upper epidermis bituminous concrete is burned, aging can be there is, Thus affect the performance of regenerated road surface, and existing technique cannot realize to reworked material accurate proportioning.
