The utility model discloses a garbage incinerator sediment to gather materials be a light, porous material, have certain compressive strength and join in marriage with the level, the chemical composition of slag shows that it has the activity and the hydraulicity, can regard as the material of substituting sub -surface. Reduce project cost makes rational use of resources.
Description
Technical field
This utility model relates to the pavement structure in field of a kind of road and bridge, particularly relates to a kind of Pavement Base Structure.
Background technology
At present, consumer waste incineration ratio ratio shared by garbage disposal is very big, and along with being continuously increased of waste incineration amount, the quantity of domestic waste incineration residue is also continuously increased. Slag still needs to carry out suitable process as a kind of solid waste. For saving the landfill place of growing tension, reducing the disposal costs of slag, reduce the impact that ecological environment is caused simultaneously, the recycling that slag gathers materials is imperative.
The pellets such as stabilized with inorganic binder crushed-gravel such as the widely used cement of domestic and international Semi-rigid Road Base Course, Calx, flyash, in recent years by the majority with cement stabilized macadam, the advantage that this compound has intensity height, good integrity, it widely uses and improves Pavement Condition and quality, but for the road engineering that road-making material resource now is increasingly deficienter, outsourcing sandstone material cost is more and more higher, seriously slow Transportation Infrastructure Construction development.
The material usage of sub-surface is very big, and building stones supply is more and more nervous, and substantial amounts of slag gathers materials and cannot dispose as garbage simultaneously. If these slags being gathered materials for sub-surface, increasingly serious road construction problem of materials can not only be alleviated, make full use of resource, alleviate slag simultaneously and discard the land seizure of generation, reduce disposal costs, both can save resource, reduce construction costs, economic and environment-friendly again.
Because the defect that above-mentioned existing Pavement Base Structure exists, the design people, actively in addition research and innovation, to founding a kind of novel Pavement Base Structure so that it is have more practicality.
Utility model content
Main purpose of the present utility model is in that, overcomes the defect that existing Pavement Base Structure exists, and provides a kind of novel pavement base layer structure, reduces construction costs, make rational use of resources, thus more suitable for practicality, and have the value in industry.
The purpose of this utility model and solve it and technical problem is that and realize by the following technical solutions. According to the Pavement Base Structure that the utility model proposes, for basic unit on road surface and road surface go to a grassroots level composition two layer composite structure, on described road surface, basic unit covers road surface and goes to a grassroots level upper surface, on road surface, the upper surface of basic unit is coated with Coarse Graded Bituminous Concrete surface layer, and described Coarse Graded Bituminous Concrete surface layer upper surface is provided with particulate formula asphalt concrete pavement; Go to a grassroots level and be arranged on ash soil layer upper surface in described road surface.
Aforesaid Pavement Base Structure, on described road surface, basic unit and road surface thickness of going to a grassroots level is 15～20cm.
Aforesaid Pavement Base Structure, on described road surface, basic unit is cement stabilizing slag crushed rock base course.
Aforesaid Pavement Base Structure, described road surface is gone to a grassroots level as cement stabilizing slag crushed rock base course, cement stabilizing slag rubble is made up of the new aggregate 70% of limestone, life garbage incinerator slag aggregate 30%, cement 4%, total Water 4.5%, wherein the particle diameter of life garbage incinerator slag aggregate is 0～5mm, new aggregate is limestone aggregates, size grading is 19-31.5mm, 10-20mm, 5-15mm, 3-5mm, and cement adopts No. 42.5 cement of normal silicate.
By technique scheme, Pavement Base Structure of the present utility model at least has the advantage that
The life garbage incinerator slag aggregate that this utility model adopts is a kind of lightweight, porous material, has certain comprcssive strength and grating, and the chemical composition of slag shows its active and hydraulicity, can the material of sub-surface as an alternative. wide for highway construction, category of roads is not high, the big dispersion of amount, invest little low-grade highway, actively utilize life garbage incinerator slag aggregate exploitation low-grade highway road surface base layer material, ensure that the pavement performance that low-grade highway sub-surface and conventional cement stabilization gravel are close, meet simultaneously and under the premise of low-grade highway operation, reduce construction costs, improve new construction and old road upgrading classification standard, adapt to the demand that the volume of traffic quickly increases, save local resources, alleviate increasingly serious road construction problem of materials, make full use of resource, alleviate slag and discard the land seizure of generation, reduce disposal costs, effectively solve environmental issue.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing describe in detail as after.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model Pavement Base Structure;
Labelling implication in figure: 1. particulate formula asphalt concrete pavement, 2. Coarse Graded Bituminous Concrete surface layer, 3. basic unit on road surface, 4. go to a grassroots level in road surface, 5. ash soil layer.
Detailed description of the invention
For further setting forth that this utility model is reach technological means and effect that predetermined utility model purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to detailed description of the invention of the present utility model describe in detail as after.
Pavement Base Structure schematic diagram of the present utility model as shown in Figure 1, Pavement Base Structure is that on road surface, go to a grassroots level the two layer composite structure of 4 compositions in basic unit 3 and road surface, two-layer arranges convenient construction, on road surface, basic unit 3 covers road surface and goes to a grassroots level 4 upper surfaces, on road surface, the upper surface of basic unit 3 is coated with Coarse Graded Bituminous Concrete surface layer 2, and Coarse Graded Bituminous Concrete surface layer 2 upper surface is provided with particulate formula asphalt concrete pavement 1; Road surface go to a grassroots level 4 be arranged on ash soil layer (5) upper surface.
