Description
Technical field
The present invention relates to road engineering technical field, slow down executing of hot-mixed bitumen pavement crack particularly to a kind of
Work method.
Background technology
Asphalt through thermoplastic elastomer modified mix with building stones build the road after, being heated has soft elasticity, catches a cold to have and mould
Rigidity, so modified asphalt concrete is apparent for jointless construction unlike cement pavement construction.During practice of construction, due to temperature
Degree difference and the existence of time difference, all seam on microcosmic.So the job specfication of bituminous paving requires: seam is tight, it is flat to connect
Suitable；The longitudinal joint of levels should stagger 150mm (hot seam) or more than 300-400mm (cold joint), adjacent two width and levels
Transverse joint all should misplace more than 1m (be all dislocation seam)；The surface layer transverse joint of highway and Class I highway should use
Vertical carvel joint, layers below can use the mitre that nature rolls, and also can make step-lap laminated when bitumen layer is thicker.Other etc.
Each layer of level highway all can use mitre, as shown in Figure 1.
Conventional pitch concrete pavement construction belongs to the hard seam between compound and compound: divide hot seam and cold joint
Seam, longitudinal joint and transverse joint.Temperature difference and time difference make seam have tiny vestige to follow, so the surface layer of highway is general
Use construction continuously, ensure that road surface is uniform as far as possible；Even so, the change of the factor such as such as weather has to stop work and understand
Produce chill seam.Municipal administration bituminous concrete pave night can not operation, laterally longitudinally all can have chill seam, if the most strictly pressing
Construct according to specification, the most high-visible seam in length and breadth；Even if standard construction, bituminous paving is subject to for a long time
To car load, temperature stress, ultraviolet irradiate, gradually produce various disease, including crack rut, loose, gather around bag, settle
Deng.Wherein to run up to winter low temperature the most in addition easy to crack for bituminous paving internal stress, it may appear that permanent cracks.Crack is
The disease that bituminous paving is most common, the most easily occurs and produces the earliest.The appearance in crack makes the seriality of bituminous paving impaired, impact
Road-ability；Rainwater snow water can ooze under crack, and then it is steady to affect roadbed, causes bigger pavement damage to reduce Colophonium
The service life on road surface.Can only, to extending the bituminous paving life-span, to carry out road surface and support by closure crack the most repeatedly at present
Protect remedial measure.But casting glue quality is uneven, and crash rate is more than 85%.Thus increase maintenance work amount, increase
Maintenance costs.How asphalt road surface, make pavement life with the ten of projected life years, 20 years the most Tong Bu, slow down road
The generation of facial cleft seam, reduce maintenance of surface remedying is to reduce road surface cost, the key extending the service life on road surface.
Summary of the invention
In view of this, the invention provides a kind of construction method slowing down hot-mixed bitumen pavement crack, the method
The internal stress of modified pitch road can be eliminated, effectively slow down the generation of pavement crack.
The invention provides a kind of construction method slowing down hot-mixed bitumen pavement crack, step includes: pave drip
When blue or green compound carries out seam, first the afterbody at the asphalt that paves spreads one layer of fine aggregate, and compacting is bonding by joint filler
On fine aggregate, then complete seam at the joint filler another side asphalt that continues to pave；Described joint filler includes: change
Property Colophonium, compound rubber asphalt, polysulfide, polyurethane rubber and Compound rubber thereof, one or more in organic silicon rubber.
The invention has the beneficial effects as follows: asphalt end passes through fine aggregate filleting, fills up the pit of coarse aggregate, then leads to
Crossing thin layer joint filler makes asphalt bank each other squeeze and bonding, it is achieved the soft seam of asphalt.Use soft
The form of construction work of seam makes road surface have fabulous high temperature performance and the ability of external force resistance deformation, and the deformation of soft seam road pavement has
Well retinue property, eliminates the internal stress of modified pitch road, can eliminate the seam of asphalt, effectively slow down road on microcosmic
The generation of facial cleft seam, reduces road surface cost, the service life on prolongation road surface.
