The problem of, and a kind of Novel asphalt concrete composite pavement proposed.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of Novel asphalt concrete composite pavement, including soil matrix, the soil matrix are equipped with lkd layer, the lkd layer
Upper layer is equipped with cement concrete slab layer, and the upper end of the cement concrete slab layer is equipped with coarse grain formula pitch mixed mud layer, described thick
The upper end of grain formula pitch mixed mud layer is equipped with middle grain formula pitch mixed mud layer.
Preferably, level offers multiple first cushion holes, each first buffering in the cement concrete slab layer
There are two the second cushion holes for the vertically symmetrical connection in the both ends in hole, and each second cushion hole all extends to middle grain formula pitch and mixes mud
Above soil layer.
Preferably, horizontal in the cement concrete slab layer to be equipped with steel mesh, and steel mesh is arranged in cement concrete slab
Layer is close to the side of coarse grain formula pitch mixed mud layer.
Preferably, the cement concrete slab layer with a thickness of 22~26cm.
Preferably, the upper end of each second cushion hole is equipped with strainer.
Preferably, the coarse grain formula pitch mixed mud layer with a thickness of 10~12com, the middle grain formula pitch mixed mud layer
With a thickness of 4~6cm.
The utility model has following advantages:
1, by the first cushion hole of setting and the second cushion hole, when the temperature of weather is higher, road surface will appear swollen
It is swollen, adequately alleviate the road surface of expansion by the first cushion hole and the second cushion hole, so that middle grain formula pitch mixed mud layer is not
It will appear bulging；When grain formula pitch mixed mud layer is rolled by vehicle in the middle, can centering grain formula pitch mixed mud layer by
Pressure buffered, centering grain formula pitch mixed mud layer is protected, the road surface made be not in fracture, subtract reduced-maintenance expense
With.
2, it by the way that the strainer that is equipped with of upper end of the second cushion hole is arranged, is in the way the rubbish on face for lattice, so that second is slow
Punching is not in blocking.
3, the toughness of cement concrete slab layer can be increased by the way that steel mesh is arranged, so that cement concrete slab layer will not go out
The case where being now broken.
In conclusion the utility model stable structure, easy to operate, design is scientific and reasonable, with short production cycle, increases water
The toughness of cement concrete plate layer, whole road surface is not in fracture in the case where vehicle is rolled with steady change, so that road surface
The service life is longer, compared with reduced-maintenance expense.
