Abstract
The utility model discloses a noise-reduction asphalt concrete road surface, which comprises a base layer (1), wherein a thin slurry sealing layer (2) is covered on the base layer (1), a coarse grain type asphalt concrete lower surface layer (3) is covered on the thin slurry sealing layer (3), and a mediate grain type asphalt concrete middle surface layer (4) is covered on the coarse grain type asphalt concrete lower surface layer (3). The noise-reduction asphalt concrete road surface disclosed by the utility model has the characteristics that a waterproofing bonding layer (5) is covered on the mediate grain type asphalt concrete middle surface layer (4), and a noise-reduction asphalt concrete upper surface layer (6) is covered on the waterproofing bonding layer (5). The utility model has the remarkable effect that the noise of traveling vehicles on the road surface can be effectively reduced.
Description
Technical field
The utility model belongs to a kind of road structure, specifically, is a kind of noise reducing type asphalt concrete pavement.
Background technology
Asphalt concrete pavement is mostly adopted on the modern urban road road surface; Its structure is as shown in Figure 1 from down to up, is followed successively by surface layer and the thick particulate formula of 4cm bituminous concrete upper layer in surface layer under basic unit, the thick slurry seal combination of 6mm～8mm priming oil, the thick coarse grain formula of the 7cm bituminous concrete, the thick middle grain formula bituminous concrete of 5cm.
Its shortcoming is: because the uppermost structure of road is a particulate formula dense-graded asphalt concrete upper layer, when the meticulous grain of automotive wheels tire pressure formula dense-graded asphalt concrete upper layer, the sound decibel that sends is higher, and noise is big.
The utility model content
The purpose of the utility model provides a kind of noise reducing type asphalt concrete pavement, can effectively reduce road surface driving noise.
For achieving the above object; The utility model provides a kind of noise reducing type asphalt concrete pavement, comprises basic unit, is coated with slurry seal above this basic unit; This is coated with surface layer under the coarse grain formula bituminous concrete above slurry seal; Surface layer in the grain formula bituminous concrete in being coated with above the surface layer under this coarse grain formula bituminous concrete, its key is: be coated with water-proof tack coat above the surface layer in the grain formula bituminous concrete in said, this is coated with noise reducing type bituminous concrete upper layer above water-proof tack coat.
Basic unit: mainly bear the effect of the wheel vertical force of surface layer transmission, and be diffused into the bed course and the soil matrix of below to it, basic unit also possibly receive surface layer infiltration and phreatic erosion.So need selection intensity higher, rigidity is bigger, and the material of enough water stabilities is arranged.
Slurry seal be for the confining surface space, prevent that moisture from invading and in basic unit making certain thickness bituminous mixture thin layer arranged.
Surface layer under the coarse grain formula bituminous concrete: bear the effect of the wheel vertical force of upper layer transmission, and be diffused into basic unit to it.
Surface layer in the middle grain formula bituminous concrete: bear the effect of the wheel vertical force of upper layer transmission, and be diffused into down surface layer and basic unit to it.
Under the coarse grain formula bituminous concrete in surface layer and the middle grain formula bituminous concrete surface layer be the interarea layer on road surface, be the major part that guarantees surface layer intensity.
Water-proof tack coat: get into surface layer in the road surface, following surface layer, basic unit and roadbed in order to prevent rainwater and road surface cleaning water, prevent that the road surface damage by water is bad, and play cementation, the material layer that strengthens pavement durability is set between road surface upper layer and middle surface layer.
Spray between said basic unit and the slurry seal priming oil is arranged.
Priming oil: be for asphalt surface course is combined well with non-bituminous material basic unit, spraying liquid petroleum bitumen, mulseal, coal tar pitch in basic unit and the thin layer that penetrates the substrate surface certain depth that forms.
Said noise reducing type bituminous concrete upper layer is a big space bituminous concrete upper layer.
Big space bituminous concrete upper layer can be with the inner dissipation of noise transmission to the road structure of wheel.Can also there be the road surface of absorption precipitation in big space, and rainwater is drained to the roadside in the bituminous concrete upper layer of big space, has improved the drainage effect of pavement of road.
Said noise reducing type bituminous concrete upper layer is the rubber asphalt concrete upper layer.
Thereby the rubber asphalt concrete upper layer can reduce the percussion on vehicle and road surface and reduce noise.
The remarkable result of the utility model is: a kind of noise reducing type asphalt concrete pavement is provided, can have effectively reduced road surface driving noise.
Description of drawings
Fig. 1 is the structural representation on existing road surface;
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing with specifically the utility model is done further explain.
As shown in Figure 2; A kind of noise reducing type asphalt concrete pavement comprises basic unit 1, is coated with slurry seal+priming oil 2 above this basic unit 1; This is coated with surface layer 3 under the coarse grain formula bituminous concrete above slurry seal+priming oil 2; Surface layer 4 in the grain formula bituminous concrete is coated with water-proof tack coat 5 in the grain formula bituminous concrete in this in being coated with above the surface layer 3 under this coarse grain formula bituminous concrete above the surface layer 4, and this is coated with noise reducing type bituminous concrete upper layer 6 above water-proof tack coat 5.
Priming oil is liquid petroleum pitch, mulseal, coal tar pitch etc.
Said noise reducing type bituminous concrete upper layer 6 is a big space bituminous concrete upper layer.
Perhaps said noise reducing type bituminous concrete upper layer 6 is the rubber asphalt concrete upper layer.
