Description
Technical field
The present invention patent discloses a kind of novel pavement compound composite type of stable granular cushion of admixture recycling powder.
Background technology
Along with development and the growth of China's Transportation Infrastructure Construction scale, the kind of engineering and construction task get more and more, all kinds of Construction Technology is constantly updated, thus workmanship requires more and more higher, is also growing to the demand of new technology, new technology, new material, new equipment.
When graded broken stone uses as bed course, there is protection earth roadbed by the erosion of water and the unfavorable natural conditions such as freezing, diffusion-induced stress effectively, the ability of good heat-insulated character, water-resisting property and drainage.Along with the development of national economy, the actual traffic volume of speedway day by day increases and even reaches capacity, and overweight overloaded vehicle is growing on and on, the destruction in various degree that caused road structure to occur.For the severe situation that current road destroys, rely on from grand highway projects LM2 contract section pavement engineering " recycling powder stablizes granular cushion application study ", by adding recycling powder in graded broken stone, develop a kind of novel pavement compound composite type, the method such as graded broken stone mixture performance and the management and control of reinforcement bed course site operation quality after not mixing recycling powder and mixing recycling powder, determine that the stable graded broken stone mixing appropriate recycling powder has better pavement performance, make express highway pavement have a more solid and stable basis; The stable granular cushion mixing appropriate recycling powder effectively can cut off underground between roadbed and road surface and the surface water, and then improves the application life of highway.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of novel pavement compound of stable granular cushion of admixture recycling powder is provided at this;
The present invention is achieved in that a kind of recycling powder of structure stablizes granular cushion, it is characterized in that; The ovum rubble that raw material selection cobble is rolled, grain size specification is: 0 ~ 2.36mm, 2.36 ~ 4.75mm, 4.75 ~ 9.5mm, 9.5 ~ 19mm, 19 ~ 26.5mm tetra-kinds.
According to claim 1, recycling powder stablizes granular cushion, it is characterized in that: construction quality mixing ratio is: 0 ~ 2.36mm:2.36 ~ 4.75mm:4.75 ~ 9.5mm:9.5 ~ 19mm:19 ~ 26.5mm=26%:12%:20%:22%:20%, mix 4 ~ 5% recycling powder outward.
The invention has the advantages that: the present invention patent discloses a kind of novel pavement compound composite type of stable granular cushion of admixture recycling powder, belongs to technological innovation, it is characterized in that: be 1. reasonable in design, meet construction needs; 2. workable, perfect, easy; 3. water permeability is strong, water-resisting property good, meets code requirement; 4. harden respond well, surface gathers materials and is not easily taken away by wheel when driving; 5. the underground between roadbed and road surface and the surface water is effectively cut off.

Detailed description of the invention
Below in conjunction with accompanying drawing 1-2, the present invention is described in detail, is clearly and completely described the technical scheme in the embodiment of the present invention, and obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The present invention patent discloses a kind of novel pavement compound of stable granular cushion of admixture recycling powder, recycling powder of the present invention stablizes the ovum rubble that granular cushion raw material selection cobble is rolled, and grain size specification is: 0 ~ 2.36mm, 2.36 ~ 4.75mm, 4.75 ~ 9.5mm, 9.5 ~ 19mm, 19 ~ 26.5mm tetra-kinds.The ovum rubble performance of this kind of raw material rolling meets quality requirement and material source is widely distributed, cheap, meets construction demand.Recycling powder of the present invention stablizes granular cushion construction quality mixing ratio: 0 ~ 2.36mm:2.36 ~ 4.75mm:4.75 ~ 9.5mm:9.5 ~ 19mm:19 ~ 26.5mm=26%:12%:20%:22%:20%, mixes 4 ~ 5% recycling powder outward.
Tool of the present invention has the following advantages: 1. reasonable in design, meets construction needs; 2. perfect, easy, workable; 3. water permeability is strong, water-resisting property good, meets code requirement; 4. harden respond well, surface gathers materials and is not easily taken away by wheel when driving; 5. the underground between roadbed and road surface and the surface water is effectively cut off.
The performance of compound and its structure close relation, for graded broken stone, mixture structure determines the performance of compound, and graded broken stone is not owing to having the cementation of the cementitious matters such as cement, lime or pitch, and the impact that its performance receives structure is more outstanding.To gather materials ratio difference according to the thickness of compound, skeleton gap structure structure, framework dense structure, suspension compact structure three kinds of physical arrangement types can be divided into.
Framework dense structure is because compactness is comparatively large, shear strength is comparatively strong, and being easy to compaction moulding during construction, is a kind of ideal structure types, and patent recycling powder of the present invention is stablized granular cushion and adopted this kind of framework dense structure.
Patent of the present invention: the recycling powder broken pebble thickness stablized selected by granular cushion is gathered materials and all adopted the cobble rolling of river along the line dam collection to form, recycling powder by road surface, the recovery that produces of cutting optimal passing material gives up powder.Each shelves gather materials all undertaken sieving by " highway engineering gather materials testing regulation " (JTGE42-2005) requirement before use, the test such as density, crush values.According to " highway road surface construction technique normalizing " (JTJ034-2000) and relevant design documentation requirements, to gather materials percent of pass according to different size, draw graded broken stone graduation curve, finally determine the ratio that different size gathers materials, make it form framework dense structure, concrete outcome is shown in accompanying drawing 1, accompanying drawing 2; Fig. 1 is that patent recycling powder of the present invention stablizes granular cushion formate gradation composition; Fig. 2 is that patent recycling powder of the present invention stablizes granular cushion formate gradation composition curve synoptic diagram.
Patent of the present invention: recycling powder is stablized granular cushion and finally determined according to the graduation curve of graded broken stone the mass ratio that graded broken stone different size gathers materials and be:: 0 ~ 2.36mm:2.36 ~ 4.75mm:4.75 ~ 9.5mm:9.5 ~ 19mm:19 ~ 26.5mm=26%:12%:20%:22%:20%, mixes 4 ~ 5% recycling powder outward.
The novel pavement compound composite type of this kind of ratio mix is adopted to start construction so far from bed course from grand highway projects LM2 contract section pavement engineering, to construct all granular cushions, proved by field practice, this patent of invention recycling powder is stablized granular cushion and is possessed good water permeability and water-resisting property, harden respond well, surface gathers materials and is not easily taken away by wheel when driving, the advantages such as the underground effectively between partition roadbed and road surface and the surface water.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
