Abstract
The utility model relates to a pavement structure, which belongs to the field of roads and bridges, and particularly relates to an asphalt concrete pavement structure. The asphalt concrete pavement structure made of stable inorganic binder brick rubble materials is characterized by comprising a fine grained asphalt concrete layer, a medium grained asphalt concrete layer, a stable inorganic binder brick rubble material layer and a gravel layer from top to bottom. 25-45 parts by weight of inorganic binders are adopted to stabilize 55-75 parts by weight of brick rubbles, so that the stable inorganic binder layer is formed. The asphalt concrete pavement structure has the advantages of actively using crushed brick rubble waste to develop low-grade road pavement base layer materials, being capable of reducing construction cost under the premise of ensuring that rural roads meet operation requirements, improving old road upgrading and modifying grade standards, meeting the demand of rapidly increasing traffic amount, saving local resources, effectively solving the problem of environmental protection, achieving remarkable economic, social and environmental benefits, and having better market prospect.
Description
Technical field
The utility model relates to a kind of road structure, belongs to the bridge field, particularly, relates to a kind of asphalt concrete pavement structure.
Background technology
At present, semi-rigid pavement basic unit extensively adopts pellets such as stabilized with inorganic binder crushed gravel such as cement, lime, flyash both at home and abroad, this compound has advantages such as intensity height, good integrity, it is extensive use of and has improved road surface functional performance and quality, but the plains region outsourcing sandstone material cost for the road materials scarcity of resources is higher, serious slow traffic infrastructure construction development.
Common brick is widely used in building construction and the Country Road Construction as constructional materials, drives and the development of promotion regional economy.And because the Urban renewal expansion has been quickened in developing rapidly of urban infrastructure, arbitrarily stacking is idle for a large amount of brickbats quilts that produce because of building is removed, and takies large-area soil, also surrounding environment and ecology is exerted a certain influence.In addition along with the continuous increase of the backroad traffic volume, the damage in various degree that the many brick road surface of building in early days also occurs, even brick body fragmentation, directly influence traffic safety, therefore with above-mentioned building is removed and the road breakage is produced brickbat material substitution crushed gravel, by the compound after the stabilized with inorganic binder such as cement, lime, flyash, can be used as the novel base material of rural highway road surface upgrading, improved the road situation, both can save resource, reduce construction costs, economic again environmental protection.
The utility model content
The purpose of this utility model provides a kind of asphalt concrete pavement structure that adopts stabilized with inorganic binder brickbat material, can reduce the engineering comprehensive cost under the prerequisite that satisfies rural low-grade highway operation demand, saves resource.
The utility model adopts following technical solution:
Adopt the asphalt concrete pavement structure of stabilized with inorganic binder brickbat material, comprise particulate formula asphalt concrete layer, middle grain formula asphalt concrete layer, stabilized with inorganic binder brickbat material layer, sandy gravel stratum from top to bottom.
Preferably, particulate formula bituminous concrete layer thickness is that 3mm, middle grain formula bituminous concrete layer thickness are that 4mm, stabilized with inorganic binder brickbat material layer are that 20mm, sandy gravel stratum are 15mm;
Preferably, particulate formula bituminous concrete layer thickness is that 3mm, middle grain formula bituminous concrete layer thickness are that 4mm, stabilized with inorganic binder brickbat material layer are that 20mm, sandy gravel stratum are 25mm;
The brickbat that the inorganic binder of employing 25～45 weight portions goes to stablize 55～75 weight portions constitutes the stabilized with inorganic binder layer.
Preferably, adopt the rendzinas of 45 weight portions to stablize the brickbat of 55 weight portions;
Preferably, adopt the brickbat of lime-flyash stabilization 75 weight portions of 25 weight portions;
Good effect of the present utility model is: actively utilize broken brickbat discarded object exploitation low-grade highway road surface base layer material, can reduce construction costs guaranteeing that rural highway satisfies under the prerequisite of operation demand, save local resources, effectively solve environmental issue.Economic benefit, social benefit and obvious environment benefit have market prospects preferably.
Description of drawings:
Fig. 1 is the structural representation of the asphalt concrete pavement structure of employing stabilized with inorganic binder brickbat material of the present utility model;
Among the figure, 1, particulate formula bituminous concrete, 2, middle grain formula bituminous concrete, 3, the stabilized with inorganic binder brickbat, 4, gravel.
The specific embodiment
As shown in Figure 1, adopt the asphalt concrete pavement structure of stabilized with inorganic binder brickbat material, comprise particulate formula asphalt concrete layer 1, middle grain formula asphalt concrete layer 2, stabilized with inorganic binder brickbat material layer 3, sandy gravel stratum 4 from top to bottom, the brickbat that the inorganic binder of employing 25～45 weight portions goes to stablize 55～75 weight portions constitutes the stabilized with inorganic binder layer, the binder difference of using, the intensity of compound is also different.Wherein adopt the rendzinas of 45 weight portions to stablize the brickbat of 55 weight portions, can possess the above intensity of 1.0MPa in its 28 days, 180 days compression rebound modulu can reach 1000～1300Mpa, satisfies low-grade highway subbase requirement of strength; Adopt the brickbat of lime-flyash stabilization 75 weight portions of 25 weight portions, can possess the above intensity of 2.6MPa in its 28 days, 180 days compression rebound modulu can reach 1400～1600MPa, satisfies the requirement of low-grade highway foundation base intension.Particulate formula bituminous concrete layer thickness is that 3mm, middle grain formula bituminous concrete layer thickness are that 4mm, stabilized with inorganic binder brickbat material layer thickness are that 20mm, sandy gravel stratum thickness are 15mm; Perhaps particulate formula bituminous concrete layer thickness is that 3mm, middle grain formula bituminous concrete layer thickness are that 4mm, stabilized with inorganic binder brickbat material layer thickness are that 20mm, sandy gravel stratum thickness are 25mm.
By the foregoing description the technical solution of the utility model is described for example, and limit the utility model never in any form, under the prerequisite that does not deviate from technical solution of the present utility model, any change or change that those of ordinary skills that the utility model is done realize easily all will fall within the claim scope of the present utility model.
