Abstract
The color concrete for road surface treatment consists of stone material, emulsion, inorganic pigment and water. The stone material is selected from limestone, diabase, basalt, copper ore, iron ore, or their mixture; the emulsion is used as the adhesive for stone material and is polymer modified emulsified asphalt; and the inorganic pigment is selected from ferric oxide, chromium oxide, cobalt oxide, etc. based on available road surface. The present invnetion has the advantages of easy construction, low cost, large load capacity, no pollution, less fading, etc.
Description
[technical field]
The present invention relates to a kind of colour concrete for road surface treatment, refer to especially that a kind of loadintensity is big, cost is low, easy construction, pollution-free, not easy to fade colour concrete for road surface treatment.
[background technology]
When carrying out the road surface processing, China generally adopts Slurry Seal Technology, its raw material is generally raw-material high-consistency mixtures such as emulsified bitumen, water, breeze, be mainly used in multi-functional maintenance to road, can lay or repair the road surfaces such as wide cut road surface on street, airport, these raw materials be laid the road surface that forms and are single color.
Along with people improve gradually to the esthetic requirement of road, previous single road color is no longer given special aesthetic feeling, at this, the mode of colourwash has just appearred directly being coated with on the road surface, though this kind mode can make the road surface present in riotous profusion color, but because of the reason of coating itself, through behind the secular wind and weather, the color of coating promptly can be died away.In addition, this kind mode also exist time-consuming, take a lot of work, take material, the high deficiency of cost.
For reducing operational procedure, color concrete has just appearred in industry, and it can be laid immediately on the road surface according to the actual requirements, need not apply coating more separately.No. the 4th, 332,620, relevant patent such as United States Patent (USP), it discloses a kind of color concrete, and this concrete composition consists of: vermiculite (2%～8%), sandstone (45%～80%), crumb rubber (6%～18%), pitch (10%～28%), ferric oxide (4%～20%).As seen from the above, the large usage quantity of this patent medium pitch, when road contribute through long mill decrease after, the part objectionable impurities in the pitch may with stir up a cloud of dust, and cause pollution to environment.In addition, the consumption of rubber is also more in this patent, because the cold and hot variation of climate may cause ageing of rubber.Because the consumption of pitch and rubber is all bigger, so the consumption of sandstone is less relatively, causes concrete insufficient strength big, generally is applied on view road, park or the walkway, can't be applied on the high strength carrying road surface.
In addition, color asphalt has also appearred in industry, it mainly is by earlier pitch being made into colour, and then join with other raw materials and make concrete to be laid on the road surface, relevant patent can be with reference to No. the 94118271.1st, People's Republic of China's publication, it has disclosed a kind of color asphalt and concrete method for making thereof, only, in this patent in preparation during color asphalt, need pitch to be heated to more than 150 ℃ in mix factory earlier, the gas environmental pollution that it gave out is very big, health to operator also can cause serious injury, generally reach 4～9cm by its concrete thickness of making, and because the performance reason of heated bitumen itself, the concrete strength that causes this to make is little, when generally only can be applicable on the Ordinary Rd, can't be applied to the high-mechanic road surface, so its existence is taken a lot of work, time-consuming, take material, to shortcoming such as human body and environmental injury be all very big.
In addition, asphalt free color asphalt also occurred, it is mainly by being made up of petroleum resin and organic high molecular polymer, its easy coloring, color category is more, but it costs an arm and a leg, complex process during use, need be heated to 160 ℃～170 ℃, be difficult to produce in enormous quantities, and by the performance of organic substance as can be known, this color asphalt very easily eclipsed under ultraviolet irradiation, in addition, under the effect of acid or alkaline matter, also very easily eclipsed.
[summary of the invention]
The object of the present invention is to provide that a kind of loadintensity is big, cost is low, easy construction, pollution-free, not easy to fade colour concrete for road surface treatment.
Another object of the present invention is to provide a kind of construction preparation method of above-mentioned color concrete.
The object of the present invention is achieved like this: this color concrete mainly comprises building stones, emulsion, water and mineral dye, and the weight percent of each composition is:
Building stones: 73%～85%
Emulsion: 7%～14%
Water: 4%～13%
Mineral dye: 2%～6%
Wherein, building stones generally can be selected material or its miscellanys such as limestone, diabase, basalt, copper mine stone, iron ore, and the grating that these building stones need satisfy following table requires:
| Sieve aperture (mm) | I type (passing through per-cent) | II type (passing through per-cent) | III type (passing through per-cent) |
| ????9.5 | ????100 | ????100 | ????100 |

| ????0.075 | ????10-20 | ????5-15 | ????5-15 |
Color concrete of the present invention can be applicable on the road surface of various grades, the grating by selecting building stones and adjust concrete thickness and get final product, and following table is the mutual relationship of grating, concrete thickness and the application of building stones of the present invention:
| The building stones grating is selected | Concrete thickness (cm) | Loadintensity (KN) | Use |
| The III type | ????＜1.2 | ????＞6.0 | High grade pavement |
| The II type | ????＜0.7 | ????＞5.0 | Common road |
| The I type | ????＜0.4 | ????＞4.0 | The view road |
Emulsion is generally selected high molecular polymer improvement emulsified bitumen mainly in order to the bonding building stones, and according to concrete range of application, its evaporation residue performance requriements is as shown in the table respectively:
| Performance | Be applied to high grade pavement | Be applied to common road | Be applied to the view road |
| Solid content | ????＞62％ | ????＞55％ | ????＞50％ |
| Ductility (25 ℃) | ????＞150 | ????＞100 | ????＞100 |

| Softening temperature | ????＞57℃ | ????＞52℃ | ????＞48℃ |
| Recovery of elasticity (25 ℃) | ????＞65％ | ????＞55％ | ????＞48％ |
According to the actual demand of road surface color, pigment can be selected mineral dyes such as ferric oxide, chromic oxide, cobalt oxide respectively for use, and makes microgranular.
Color concrete of the present invention can directly prepare and construct at the scene, and the preparation method that specifically constructs is as follows:
The road surface of packing into respectively such as building stones, emulsion, water, mineral dye is handled in the hopper of specific equipment correspondence, and by this equipment control corresponding device, the raw material of controlling in each hopper enters in the agitator tank of this equipment according to a certain ratio, pass through the stirring action of agitator tank and make building stones, emulsion, water and mineral dye etc. fully mixed (physics is mixed), material after mixed flows in the case that paves of this equipment again, can carry out pavement spread.
Compare with the color concrete that existing road surface is used, because the binding material that the present invention uses is the improvement emulsified bitumen, thus before mix, need not the emulsion heating has been avoided the injury of human body and the pollution of environment, and easy construction, reduced raw material and cost of labor; In addition, because solid content height, the adhesive power of improvement emulsified bitumen are strong, so cooperated the concrete that forms with building stones by it, under condition of equivalent thickness, loadintensity far beyond existing color concrete is big, therefore, color concrete of the present invention not only can be applicable on general the view road and ordinary road, also can be applicable on the road surface of high-grade, high pressure-bearing; Moreover because used pigment is mineral dye, it is water insoluble, also is not subjected to the corrosion of materials such as ultraviolet ray, acid, alkali, so the colored road surface of being laid by this color concrete extremely is difficult for eclipsed.
