Side of the bituminous concrete far from particulate formula bituminous concrete and the crushed rock base course being filled in skewed slot contradict.
Using the above scheme, the laying of particulate formula bituminous concrete and middle grain formula bituminous concrete different size improves drip
The strength and stability on green road surface.
Preferably, being equipped with Coarse Graded Bituminous Concrete, the coarse grain formula below the middle grain formula bituminous concrete
Side of the bituminous concrete far from middle grain formula bituminous concrete and the crushed rock base course being filled in skewed slot contradict.
Using the above scheme, the bituminous concrete of different gradation type makes bituminous paving form closely knit, stable, roughness and fit
Preferably, long-lived road surface.
Preferably, the middle grain formula bituminous concrete is laid with the trapezoidal shape of Coarse Graded Bituminous Concrete.
Using the above scheme, the laying of trapezoidal shape so that the crushed rock base course from cement pavement to bituminous paving and coarse grain formula
The trapezoidal shape setting of splicing of bituminous concrete so that the road surface of stitching portion has certain changeover portion, and then prevents in stitching portion
Generate pit slot.
Preferably, being provided with drainpipe in the crushed rock base course that the cement pavement is laid with.
Using the above scheme, on the surface of cement pavement there are when certain ponding, the setting of drainpipe, convenient for by rainwater into
Row is collected and then is drained into blowoff basin, reduces the amount of ponding on cement pavement to a certain extent.
Preferably, being provided with drainpipe in the skewed slot.
Using the above scheme, in skewed slot drainpipe setting, the rainwater convenient for being oozed out from bituminous concrete is quickly discharged into
To stormwater tank, and then influence of the rainwater to bituminous paving is reduced to a certain extent.
In conclusion the utility model has the advantages that：The setting of bearing plate, buffer stopper so that from cement road
The upper surface of face to bituminous paving stitching portion has certain buffering, transition, and then improves the stability and flatness of stitching portion,
Reduce the influence to driving vehicle.
