Description
Technical field
The present invention relates to antiskid wearing layer of a kind of epoxy asphalt pavement and preparation method thereof.
Background technology
Epoxy asphalt pavement relies on its excellent performance, from domestic calendar year 2001 after the successful Application of yangtze river in nanjing two bridges, obtain promoting on the projects such as Jiang Daqiao, yangtze river in nanjing three bridges, the logical bridge of Soviet Union of making the best use of the advantages in profit in succession.According to statistics, a bridge adopts the bituminous epoxy paving steel bridge deck surplus in the of at present domestic existing 30, and the area of mating formation surpasses 500,000 m
2
Yet the used mixture structure of epoxy asphalt pavement is a suspension density structure, and porosity is little, and the fines accounting is big, so the epoxy asphalt pavement smooth surface, the macrostructure degree of depth is little.Following table 1 is depicted as the cling property parameter comparison on domestic several kinds of road surfaces commonly used.It is thus clear that epoxy asphalt concrete (EA) is on the low side with respect to the cling property on SMA commonly used and OGFC road surface.
Table 1 pavement structural depth contrast commonly used
| Title | Construction depth/mm |
| SMA13 | ＞0.8 |
| OGFC13 | ＞1.5 |
| EA13 | ＜0.5 |
China early introduces the Nanjing Er Qiao of epoxy asphalt pavement; Three bridges, profit are raised bridge, the logical bridge of Soviet Union used respectively about 10 years, 5 years, 5 years, 3 years; Can estimate that along with the increase in age of domestic epoxy asphalt pavement road, the emphasis of steel bridge face epoxy asphalt pavement will be by being main with construction; Lay equal stress on to building, and be that main direction develops to maintenance gradually with maintenance.
The preventive maintenance technology of flexible pavement commonly used all adopts pitch class material as cementitious matter like little table place, slurry seal etc. both at home and abroad, under vehicular load, is prone to take place shear failure.Preventive maintenances such as domestic little table place commonly used, slurry seal, cover technology, not enough with the epoxy asphalt pavement adhesion strength, be not suitable for the maintenance of epoxy asphalt pavement.Because the preventive maintenance of present domestic shortage epoxy asphalt pavement technology; Support pipe department generally when the disease of epoxy asphalt pavement injures steel plate safety; Promptly carry out the medium-capital overhauling maintenance, caused the consumption of a large amount of maintenance funds, and had a strong impact on traffic mating formation.
Summary of the invention
The objective of the invention is provides the antiskid wearing layer of a kind of making on epoxy asphalt pavement in order to solve the deficiency of existing epoxy asphalt pavement maintenance technology and surperficial cling property.
In order to achieve the above object, the invention provides a kind of antiskid wearing layer of epoxy asphalt pavement, this antiskid wearing layer is formed by epoxy resin and the rubble curing that is spread in epoxy resin surface, and gross thickness is 1～2mm; The antiskid wearing layer upper epidermis is the rubble exposed part that is solidificated in the epoxy resin; Content of epoxy resin is 1～1.5kg/m
2, the rubble consumption is 1～1.2kg/m
2
The present invention also provides a kind of antiskid wearing layer preparation method of epoxy asphalt pavement, may further comprise the steps:
(1) extracting epoxy resin and curing compound mix, stir;
(2) adopt mechanically spraying spreading or manual work to coat the epoxy asphalt pavement surface epoxy resin that mixes in the step (1) and curing compound, form sizing material; Wherein the consumption of epoxy resin is 1～1.5kg/m
2
(3) spreading one deck rubble in the surface of the sizing material in step (2) makes it to solidify with the epoxy resin sizing material, finally forms antiskid wearing layer; The spreading amount of rubble is 1～1.2kg/m
2Gained antiskid wearing layer gross thickness is 1～2mm, and its upper epidermis is the rubble exposed part that is solidificated in the epoxy resin.
Further improvement of the present invention is that above-mentioned rubble is spread in uniform in epoxy resin surface, and its medium stone partly is embedded in the epoxy resin, and part is exposed at epoxy resin surface.Rubble adopts simple grain footpath basalt; Particle diameter accounts for below 5% of rubble gross weight greater than the rubble of 1.18mm in the rubble; Particle diameter accounts for below 5% of rubble gross weight less than the rubble of 0.6mm, and particle diameter accounts for below 1% of rubble gross weight less than the rubble of 0.075mm, rubble washing and oven dry; And moisture content is less than 1%, and preferable particle size is 0.6～1.18mm; The preferred bisphenol A type epoxy resin of epoxy resin, the preferred amine curing agent of curing compound.
The present invention has the following advantages:
Adopt epoxy resin rubble ultra-thin wearing layer, rely on epoxy resin self high strength and with the high bond strength of epoxy asphalt pavement, can form integral body with former epoxy asphalt pavement, bear vehicular load; Simultaneously to epoxy resin surface spreading simple grain footpath rubble; Make rubble partly be mounted in the resin; Part is exposed at resin surface, treat that it solidifies after, the rough surface that the epoxy resin macadam relies on exposed rubble to form can improve the cling property of former epoxy asphalt pavement; Rely on the high osmosis ability of epoxy resin, the epoxy resin macadam can be filled up the crack of epoxy asphalt pavement, plays the effect of structural strengthening.
The specific embodiment
Below in conjunction with embodiment the antiskid wearing layer of epoxy asphalt pavement of the present invention is elaborated.
The material preferred embodiment
For the crack of the epoxy asphalt pavement that heals, cling property, water resistance and the durability that raising is mated formation, the present invention at first screens rings of material epoxy resins and rubble.
1, epoxide resin material performance requirement:
