Description
Technical field:
The utility model relates to a kind of flexible pavement layering hot recycling machine, is a kind of flexible pavement layering hot recycling construction operation special equipment, belongs to sheet pavement in-situ regeneration technical field of construction equipment.
Background technology
Conventional flexible pavement in use
,under the effect of traffic load and climatic effect, along with the passing of service time, pavement behavior and service ability will run down.There will be such as cheat groove, hire bag, disease road surface that be full of cracks, purt slurry, rut, crackle etc. are dissimilar, these diseases many times appear at each layer of flexible pavement, after disease acquires a certain degree, just need heavily to be spread by flexible pavement or repair
.and by using the reparation of Heat-recycling Maintenance Equipment for Asphalt Pavement and maintenance construction technology thereof, owing to can 100% achieving former ground surface material in-place regeneration and utilize, save a large amount of resources, circular regeneration; Carbon emission, less than traditional handicraft 10%, meets national recycling economy, most attention that thus developing direction of low-carbon economy obtains people.In the operation of asphalt surface hot reproduction maintenance construction, first sheet pavement in-situ heat regeneration vehicle is used to heat the bituminous mixture of disease flexible pavement, the mode of rake pine or milling is broken by disease flexible pavement, and will be new by asphalt surface hot reproduction car, old regenerating mixture gathers materials, namely in the middle part of road surface, be concentrated into band (being called pitch material strip), mix the new bituminous mixture of proper proportion again, be incubated, heating mixing, add new regenerative mixed by the waggon of bituminous mixture again and expect the flexible pavement needing regeneration, and stir in bituminous mixture lifting to remixer, then send in hopper of paver thereafter
,finally paved by paver, road roller compacting forms new flexible pavement.This process has uninterruptedly been constructed by multiple devices associating, as sheet pavement heating vehicle (heat effect), asphalt surface hot reproduction car (rake pine or the effect of gathering materials), the equipment such as remixer (mixing and stirring effect) and paver that promote are worked continuously and just can be completed.Implement just because of needing the construction of multiple devices, Construction traffic length can be caused to increase, the degree of depth of heating is difficult to reach construction requirement (only 4cm), and whether sheet pavement in-situ heat regeneration construction quality can be guaranteed, extremely important condition is that reclaimed asphalt mixture must ensure enough temperature (actual temp is relevant with bituminous mixture classification) before again paving, next is that before must ensureing again to pave, there are enough temperature on road surface under regeneration zone to ensure the adhesion strength of regeneration zone and lower floor, also to there be enough regeneration degree of depth in addition, guarantee road surface has enough intensity not damaged by pressure.The local hot reproduction construction method of currently available technology can only carry out the construction of flexible pavement upper layer, then can not carry out in-situ heat regeneration, limit the range of application of hot in-place recycling technology for middle surface layer and cutting optimal.And in the construction of existing in-situ heat regeneration not further by harrow pine collect after road surface carry out heating rake pine again and collect with the road surface bulk strength after increasing the degree of depth to have improved.The regenerated road surface quality of the new and old regenerating mixture reached required by its construction can be affected.
Utility model content
