Abstract
The utility model discloses a kind of repairing type bituminous paving, including old layer roadbed, crushed rock base course, cement stabilized macadam layer, asphalt concrete layer and modified stone mastic asphalt surface layer are equipped with the old layer roadbed successively；Steel wire grid is also equipped with the pit and crushed rock base course of basic unit's roadbed；The cement stabilized macadam layer is equipped with primary coat and steel wire grid successively with asphalt concrete layer.The utility model has advantages below and effect：By setting up steel wire grid between old layer roadbed and crushed rock base course and equally setting up steel wire grid between cement stabilized macadam layer and asphalt concrete layer, it is final to cause the road surface repaired that there is stronger antiskid performance, strengthen tension, shearing resistance, resistance to compression and shock proof intensity, improve combination property.
Description
Technical field
The utility model is related to pavement construction field, more particularly to a kind of repairing type bituminous paving.
Background technology
Existing road surface is spread just using cement or pitch mostly.After the completion of road surface, whole road surface is to be relatively fixed,
A certain degree of breakage necessarily occurs in road surface after use after a while, and the Re-paving transformation for causing road surface is always building
The focus that road work person pays close attention in industry.Wherein the Moisture Damage of bituminous paving be mainly shown as on road surface loosely, produce hole
Groove etc., directly contributes the destruction of asphalt pavement structural layer, has had a strong impact on the use function on road surface, shortens the use longevity on road surface
Life.And this disease is difficult in road surface operation phase maintenance, it must again be spread from roadbed to road-surface milling, cause unnecessary waste.
Utility model content
The purpose of this utility model is to provide a kind of pit and repairs the high repairing type bituminous paving of rear stability.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of repairing type asphalt road
Crushed rock base course, cement stabilized macadam layer, asphalt concrete layer are equipped with face, including old layer roadbed, the old layer roadbed successively
And modified stone mastic asphalt surface layer；Steel wire grid is also equipped with the pit and crushed rock base course of basic unit's roadbed；Institute
State cement stabilized macadam layer and be equipped with primary coat and steel wire grid successively with asphalt concrete layer.
By using above-mentioned technical proposal, when repairing pit, first the pit of old layer roadbed can be purged totally,
Then lay a steel wire grid and carry out smooth, the structural strength of enhancing pit bottom, then fill up rubble one crushed rock base course of formation,
After the roadbed filling completely of the bottom of pit, filling concrete stabilization gravel layer forms being fixed of metalling of lower floor
The surface of one smooth compacting；Steel wire grid and primary coat are re-layed on a surface, enabling mixed with the pitch of upper end
There is stronger structural strength while the solidifying more preferable transition of soil layer and effective connection.Finally in the upper end of the asphalt concrete layer
Pour modified asphalt-mastic-broken stone surface layer and carry out sealing, improve abrasion and the antiskid performance on road surface at this, enhancing tension,
Shearing resistance, resistance to compression and shock proof intensity, improve combination property.
It is of the present utility model to be further arranged to：The coarse grain formula pitch that the asphalt concrete layer includes 7.5 ~ 8.5cm is mixed
The middle grain formula asphalt concrete layer of solidifying soil layer and 5.5 ~ 6.5cm.
By using above-mentioned technical proposal, the maximum particle diameter that asphalt concrete layer gathers materials preferably gradually increases from upper strata to lower floor
Greatly, to prevent oozing under water, and and good structural strength.
It is of the present utility model to be further arranged to：The primary coat, Coarse Graded Bituminous Concrete layer, the middle grain
Modified emulsifying asphalt adhesion coating is provided between formula asphalt concrete layer, each layer of modified stone mastic asphalt surface layer.
By using above-mentioned technical proposal, setting up for modified emulsifying asphalt adhesion coating promotes the connection type between every layer, really
Preferably merged between protecting layer by layer.
It is of the present utility model to be further arranged to：The cement stabilized macadam layer includes 24 ~ 25cm cement stabilized macadam
Go to a grassroots level, basic unit on 19 ~ 20cm cement stabilized macadams.
In summary, the utility model has the advantages that：By setting up steel between old layer roadbed and crushed rock base course
Silk grid and steel wire grid is equally set up between cement stabilized macadam layer and asphalt concrete layer, it is final to cause what is repaired
Road surface has stronger antiskid performance, and enhancing tension, shearing resistance, resistance to compression and shock proof intensity improve combination property.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing 1 and Fig. 2.
A kind of repairing type bituminous paving, including old layer roadbed 1, carry out the pit in old layer path to handle clean first,
A steel wire grid 2 is then directly directly laid, the rubble for then laying 20 ~ 23cm is tamped, form crushed rock base course 3.
Cement stabilized macadam layer 4 is set up on crushed rock base course 3, cement stabilized macadam layer 4 includes 25cm cement stabilized macadams
Go to a grassroots level 42（Wherein cement content 4%）And basic unit 41 on 20cm cement stabilized macadams（Cement content 5%）.
The upper berth primary coat 6 of basic unit 41 on cement stabilized macadam, is then implanted to the primary coat 6 by steel wire grid 2
On, the primary coat 6 is strengthened, primary coat 6 can be strengthened into cement stabilized macadam layer 4 and the pitch of upper strata setting is mixed
Solidifying soil layer 5 is preferably combined.
Asphalt concrete layer 5 includes 8cm 51 and 6cm of Coarse Graded Bituminous Concrete layer middle grain formula bituminous concrete
