Description
One, technical field
The present invention relates to pavement engineering and job practicess thereof such as highway construction, especially a kind of rolling has the honeycombed cement of tack coat rigid pavement and job practices on the cement concrete.
Two, background technology
1, rolls cement concrete
Rolling cement concrete is a kind of new concrete that grows up in the last thirty years.It has particular performances; The performance of roller compacted concrete is not different from conventional concrete fully before not solidifying; Not solidified roller compacted concrete denseness is very dried, also does than the no slump concrete of worker China Democratic National Construction Association, is that a kind of slump is zero ultra no slump concrete; It can make bulldozer, road roller work and do not sink above that, and is very approaching with the concrete performance of routine again after solidifying.Roller compacted concrete makes stone overcome frictional resistance and occupies space formation skeleton through the effect of vibration force, and hole is filled and parcel by cement mortar, forms compacting body.
Roll that cement concrete has that the construction machinery capacity is big, speed is fast, the characteristics of large tracts of land operation.It has intensity height, good endurance, saving cement, advantage that drying shrinkage is little.
Roll cement concrete and aspect the build of the build of water conservancy project dam body and high grade highway pavement more application is being arranged.
2, the problem that exists
When rolling cement concrete directly as the road surface of high-grade highway, because its compaction technology that adopts often makes the road surface uneven, surface evenness is bad, can not satisfy the needs of high speed traveling, the basic unit that therefore is commonly used to do factories and mines road or high-grade highway.
When rolling cement concrete as the basic unit of high-grade highway, making asphalt surface course often on it, the structure of this form often is called as " morning-night ".Need before the asphalt concrete to spill asphalt of penetrate layer and adhesion coating pitch on the cement concrete surface below, with bituminous concrete and the Portland Cement Concrete Surface Course bonds well that guarantees to overlay, with effects such as common bearing loads.Though adhesion coating, generally employing of layer thoroughly; But because the modulus of elasticity of bituminous material and cement concrete material great disparity is big, temperature deformation coefficient difference is bigger; Be difficult for accomplishing bonds well generally speaking, this also is short basic reason " morning-night " general service life.
In addition, because the poor durability of pitch class material, service life is short, and comprehensive cost is expensive.
Three, summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, easy construction adopts formed the rolling of honeycombed cement concrete that the honeycombed cement of tack coat rigid pavement and job practices are arranged on the cement concrete.
The present invention adopts single-stage to join or the second wife's rubble that breaks; Make it evenly to mix with cement, sand, water; The honeycombed cement concrete material of hole is rich in formation; The machinery that employing has leveling, jolt ramming function paves, utilize spreading machine leveling certainly, guarantee the closely knit, smooth of surface layer from the jolt ramming function.The porous concrete material has kept the high strength of cement class material; Because porous concrete belongs to framework dense structure, therefore contraction reduces simultaneously, and the strain during destruction increases---deformability strengthens, and demonstrates plastic property during destruction, has increased the adaptive capacity of surface layer; The employing of multi-pore structure makes the road surface can permeable, noise reduction, has improved the service performance of cover, adopts the paver construction, and construction is applicable to extensive construction simply, easily and fast, and economy is strong.
The technical scheme that the object of the invention adopted is its structure: include and roll the cement concrete bottom, be provided with tack coat rolling the cement concrete bottom surface, making has the honeycombed cement concrete pavement on the tack coat.
The present invention rolls the cement concrete bottom and rolls Portland Cement Concrete Surface Course or basic unit for what form in advance.
The present invention, tack coat is the waterproof thin layer that the compound by polymer or polymer and filler forms, can with its under roll the cement concrete bottom with its on honeycombed cement concrete pavement secure bond.
The present invention; The used honeycombed cement concrete of honeycombed cement concrete pavement is made up of rubble and sand, cement, the water of gap grading or single grating; Every cubic meter of concrete does by weight ratio---cement: rubble: sand: water=150～450kg: 1200～2200kg: 0～500kg: 60～180kg forms the cement concrete that contains hole.
The present invention, polymer and filler weight proportioning that tack coat adopts do---polymer: filler=1: 0～15.
The present invention, the used polymer of tack coat is fluoropolymer resin, polymer powder, also can be polymer emulsion.
The present invention, the used filler of tack coat is active filler, comprises cement or flyash, is inert filler perhaps, comprises calcium carbonate or French chalk or quartz sand, perhaps is the mixture that different fillers is formed.
The present invention adds in the polymer that tack coat is used and the compound of filler that corresponding thinner dilutes, auxiliary agent, and the weight proportion of polymer and thinner, auxiliary agent does---polymer: thinner: auxiliary agent=1: 0～10: 0～2.
The present invention; Construction method step is following: cleaning rolls foreign material and the floating dust on the cement concrete bottom, by weight polymer and filler being adopted machinery or manual stirring even, and the compound of formation polymer and filler; Adopting machinery or manual work evenly to pave polymer composition is rolling on the cement concrete bottom; Form tack coat,, adopt spreading machine or the manual work honeycombed cement concrete that paves then by weight adopting machinery or artificial cement, rubble, sand, water are evenly stirred to form the honeycombed cement concrete; Utilize spreading machine or the concrete leveling of artificial realization honeycombed cement, compacting; After maintenance 1-7 days, form the honeycombed cement concrete pavement, and secure bond is on tack coat.
Overlaying portland cement concrete on the present invention and the existing asphalt surface course has very big difference, is embodied in:
(1) honeycombed cement concrete of the present invention is compared with existing common solid cement concrete, and its material structure is different, and its bonding layer material is also inequality; Corresponding therewith, the design of ground surface material match ratio is different, and road structure is also different; Surface layer is the matrix porosity structural meterials among the present invention, and shrinkage factor is much smaller than common solid cement concrete, the not ad hoc usually tack coat of Portland cement concrete pavement; The road surface early damage is serious, among the present invention adhesion strength much larger than existing road surface binding material.
(2) construction technology is obviously different; Because the rigid material property of honeycombed cement concrete dry among the present invention, for paving of road surface can adopt that asphalt paver or manual work pave, leveling, compacting, be different from paving of road surfaces such as existing cement concrete and bituminous concrete; Do not need road roller to roll; Therefore construction technology of the present invention is simple and convenient, realizes easily, is convenient to promote.
To sum up, the present invention is a kind of new novel road surface structure that is different from existing various road structures.Functions such as that the road surface had both had was permeable, noise reduction, the contraction that is brought by cement simultaneously significantly reduces, and road surface bonding layer material adhesion strength is high, and road structure is reasonable.
The present invention can guarantee that good road with the thickness that significantly reduces top course under the prerequisite, brings remarkable economical property, draws materials conveniently in the road surface, and construction is simple, quick.
Four, description of drawings
Further specify the present invention in conjunction with accompanying drawing.
