Description
One, technical field
The present invention relates to pavement engineering and job practicess thereof such as highway construction, especially a kind of asphalt surface course is provided with the honeycombed cement surface concrete membrane and the job practices of tack coat.
Two, background technology
1, the asphalt surface course cover, add laying method
Asphalt surface course is one of main road surface form of generally adopting of highway and urban road, when asphalt surface course needs cover, when overlaying, selects following dual mode at present for use:
One, on asphalt surface course, overlay cement concrete.In this case, the material of overlay is a cement concrete, and the cement concrete of overlay belongs to compact structure, and it forms by cast, Vibration Technology.
Two, on asphalt surface course, overlay bituminous concrete.Need to spill on the cement concrete surface below asphalt of penetrate layer and adhesion coating pitch before the asphalt concrete, with bituminous concrete and the asphalt surface course bonds well that guarantees to overlay, with effects such as common bearing loads.
2, the problem of Cun Zaiing
When overlaying cement concrete layer, traditional portland cement concrete belongs to fragile material, and deformability is little, and is easy to crack, and to supporting situation sensitivity, the road surface easily produces disease, and when constructing in addition, concrete shrinkage is big, also can cause concrete cracking.
When the making bitumen layer, because the poor durability of pitch class material, service life is short, still may need after several years to overlay the comprehensive cost costliness.
Three, summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, easy construction adopts the formed asphalt surface course of honeycombed cement concrete to be provided with the honeycombed cement surface concrete membrane and the job practices of tack coat.
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 presents 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 purpose of the present invention adopted is its structure: include asphalt surface course, be provided with tack coat on the asphalt surface course surface, honeycombed cement surface concrete membrane layer is arranged on the tack coat.
The present invention, asphalt surface course is that the utilization bituminous material that forms is in advance built the surface layer that forms, asphalt surface course is asphalt concrete pavement or asphalt macadam surface layer etc.
The present invention, tack coat is the waterproof thin layer that the compound by polymer or polymer and filler forms, can with asphalt surface course and the honeycombed cement surface concrete membrane layer secure bond on it under it.
The present invention, the used honeycombed cement concrete of honeycombed cement surface concrete membrane layer is made up of rubble and sand, cement, the water of gap grading or single grating, every cubic meter of concrete is 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, tack coat adopts the compound of polymer or polymer and filler, and polymer and filler are by weight ratio: polymer: filler=1: 0～15.
The present invention, the used polymer of tack coat is fluoropolymer resin, polymer powder or is polymer emulsion.
The present invention, the used filler of tack coat is active filler, comprises cement, flyash; Be inert filler perhaps, comprise calcium carbonate, French chalk, quartz sand; It perhaps is the mixture that different fillers is formed.
The present invention, the compound of polymer that tack coat is used or polymer and filler adds corresponding thinner, auxiliary agent, and the weight proportion of polymer and thinner, auxiliary agent is---polymer: thinner: auxiliary agent=1: 0～10: 0～2.
The present invention, construction method step is as follows: foreign material and floating dust on the cleaning asphalt surface course, polymer and filler 1: 0 by weight～15 adopted machinery or manually stir, form the compound of polymer and filler, the compound of polymer and filler is adopted machinery or manually evenly pave on asphalt surface course, form tack coat, then with cement, rubble, sand, water adopts machinery or artificial evenly the stirring to form the honeycombed cement concrete material by weight 150～450: 1200～2200: 0～500: 60～180, again with spreading machine or the honeycombed cement concrete that manually paves, realize the concrete leveling of honeycombed cement, compacting, after maintenance 1-7 days, form honeycombed cement surface concrete membrane layer, 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, its material structure difference, its bonding layer material is also inequality, and is corresponding therewith, and the design of ground surface material match ratio is different, 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, and adhesion strength is much larger than existing road surface binding material among the present invention.
(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 asphalt paver or manually 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, road surface bonding layer material adhesion strength height, 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, draws materials conveniently in the road surface, and construction is simple, quick.
