Background technology
Reach service life road surface in the number of loading using latter stage Old cement concrete structure to generate not
With the destruction of degree, it is impossible to direct Paving Bituminous Concrete layer, it is therefore desirable to respective handling is carried out for old pavement different diseases,
So that its intensity reaches overlay and required, while also contribute to improve the bulk life time of overlay.Then according to old road typical disease
Disposal, relative settlement influence to study respectively, by different structure combinations and the analysis of structural material parameter, drawing optimal
Overlay and the combination of new pavement structure.The domestic corresponding renovation technique scheme of cement pavement shows becoming for diversification at present
Gesture, the progress degree of correlation technique differ, and during towards Practical Project, are also carried not a set of for old road difference actual state
The systems technology system gone out.
In addition, difference of the new-old concrete bond road surface due to the road construction time, causes the roadbed degree of consolidation and each structure to be laminated
The difference of contracting degree, so as to cause the difference on new-old concrete bond road surface, there is crack, breakage, depression, driving in sedimentation joint portion road surface
Phenomena such as uncomfortable, and then cause service life of road surface to be decayed.Therefore widening pavement overlay and new pavement knot how to be selected
Structure is particularly important, and suitable Pavement Base Structure can reduce additional stress caused by relative settlement, so as to improve road indirectly
The service life in face.
Utility model content
(1) technical problem solved
In view of the shortcomings of the prior art, the utility model provide a kind of old cement concrete road widen transformation pavement structure group
Close so that relative settlement is reduced on road surface, improves service life.
(2) technical scheme
To realize object above, the utility model is achieved by the following technical programs：
A kind of old cement concrete road widens transformation Pavement Structure Combination, including Old cement road section and widened section, the old cement
Section includes old cement panel and cement treated material from top to bottom, and the widened section includes widening cement treated material, and described to widen water steady
Basic unit connects with the old cement panel of Old cement road section with cement treated material, the Old cement road section and widened section junction cutouts
Widen cement treated material, form two stage steps, be filled using cement concrete.
Further, the Old cement road section top surface and widened section top surface are in same level.
Further, the Old cement road section and widened section stitching portion top surface are provided with anti-splitting paster.
Further, the width of the anti-splitting paster is 0.5-1m, thickness 2mm.
Further, the two stage steps height and width are 50cm.
Further, difference in height≤3mm between the old cement panel of Old cement road section, old cement panel pavement condition index
>=70, disconnected plate rate≤5% of old cement panel, old cement panel flexural tensile strength >=4.5Mpa.
(3) beneficial effect
The utility model provides a kind of old cement concrete road and widens transformation Pavement Structure Combination, and its advantage is：
1st, the utility model realizes old cement concrete road and recycled, and method is simply easily operated, and construction cost is relatively low.
2nd, the utility model solves the problems, such as the combination between pavement structure and old line structure, avoids because service life is poor
Different and pavement structure early damage caused by new-old road combination is mishandling.
3rd, the utility model can avoid pavement structure early disease from producing, and reduce economic waste and negative social environment
Influence.
