Abstract
The invention provides a diluted emulsified asphalt slurry mixture for repairing tracks in an asphalt pavement. The mixture comprises an aggregate, emulsified asphalt and water, wherein the weight of the asphalt is 5 to 7 percent of the total weight of the aggregate; according to different grain diameters, the aggregate comprises the following components in portion by weight:: 4 to 19 portions of components with a grain diameter of below 0.075mm, 2 to 4 portions of components with a grain diameter of between 0.075 and 0.15mm, 2 to 6 portions of components with a grain diameter of between 0.15 and 0.3mm, 5 to 7 portions of components with a grain diameter of between 0.3 and 0.6mm, 6 to 8 portions of components with a grain diameter of between 0.6 and 1.18mm, 8 to 11 portions of components with a grain diameter of between 1.18 and 2.36mm, 11 to 17 portions of components with a grain diameter of between 2.36 and 4.75, 15 to 22 portions of components with a grain diameter of between 4.75 and 9.5mm, 9 to 14 portions of components with a grain diameter of between 9.5 and 13.2mm, 5 to 10 portions of components with a grain diameter of between 13.2 and 16mm and 5 to 10 portions of components with a grain diameter of between 16 and 19mm. Compared with the prior MS-3 type micro surfacing diluted emulsified asphalt slurry mixture, the diluted emulsified asphalt slurry mixture has the advantages of improving the track resistance of the repaired pavement, simplifying of the double-layer micro surfacing track repairing process, shortening the track repairing period of the pavement, lowering constructional cost, avoiding the waste due to the repeated track repairing and improving the operational efficiency.
Description
Technical field
The present invention relates to the repairing asphalt pavement rut material therefor, refer to a kind of emulsified bitumen slurry mixture for repairing asphalt pavement rut especially.
Background technology
The motorway that China has built up and the common road overwhelming majority are bituminous pavements.Because the influence of factors such as vehicle seriously transfinites, heavy traffic and canalization driving causes rut to become one of main disease of bituminous pavement.According to statistics, rut in various degree appears in 80% bituminous pavement.Repair the technical scheme that rut is comparison science, economy with emulsified bitumen slurry mixture.At present, for the rut of degree of depth 20mm, adopt the little table of double-deck MS-3 type place to repair usually both at home and abroad.(wherein MS is the abbreviation of English Micro-Surfacing at the little table of MS-3 type place, the 3rd, III type grating) be that to gather materials by particle diameter be that fine rock material, particle diameter below the 2.36mm is that the middle rubble material of 2.36～4.75mm and rubble material that particle diameter is 4.75～9.5mm are mixed by the standard proportional range, gather materials and stir into emulsified bitumen slurry mixture with cooperations such as emulsified bitumen and water again, and pave rapidly on former road surface, through the pavement structure of maintenance moulding (being the process of water consumption).Maximum ballast grain sizes 9.5mm in gathering materials, it is 10mm that thickness is repaired at the little table of individual layer place, it is 20mm that double-layer micro-surfacing is repaired thickness.In actual applications, the ability of making the anti-rut of pavement structure that double-layer micro-surfacing repairs with this emulsified bitumen slurry mixture is relatively poor, new rut can occur again after using for some time on double-layer micro-surfacing.Current specifications is defined between the construction at two-layer little table place must open to traffic more than 24 hours, and the result causes twice construction in same highway section to seal twice traffic, not only can make a big impact to highway is current, and can cause very big financial loss.
Summary of the invention
Technical problem to be solved by this invention provides a kind of in the ability that improves the anti-rut of repairing at little table place in road surface, and help the simplification that rut technology is repaired at little table place, can shorten the emulsified bitumen slurry mixture for repairing asphalt pavement rut that pavement track is repaired the duration, reduced construction cost.
The technical scheme that adopts for addressing the above problem is: emulsified bitumen slurry mixture for repairing asphalt pavement rut, comprise gather materials, emulsified bitumen, water.Wherein institute's bituminous accounts for 5～7% of the gross weight of gathering materials in the emulsified bitumen, and total water accounts for 4～10% of the gross weight of gathering materials, and the different-grain diameter component and the weight part scope thereof of gathering materials are:
0.075mm 2～4 parts of following 4～19 parts of 0.075～0.15mm
0.15 5～7 parts of 2～6 parts of 0.3～0.6mm of～0.3mm
0.6 8～11 parts of 6～8 parts of 1.18～2.36mm of～1.18mm
2.36 15～22 parts of 11～17 parts of 4.75～9.5mm of～4.75mm
9.5 5～10 parts of 9～14 parts of 13.2～16mm of～13.2mm
5～10 parts of 16～19mm
In described emulsified bitumen slurry mixture for repairing asphalt pavement rut, to account for the preferable per-cent of the gross weight of gathering materials be 6% to institute's bituminous in the described emulsified bitumen, the preferable per-cent that total water accounts for the gross weight of gathering materials is 7%, and described different-grain diameter component of gathering materials and preferable weight part thereof are:
0.075mm 3 parts of following 11.5 parts of 0.075～0.15mm
0.15 6 parts of 4 parts of 0.3～0.6mm of～0.3mm
0.6 9.5 parts of 7 parts of 1.18～2.36mm of～1.18mm
2.36 18.5 parts of 14 parts of 4.75～9.5mm of～4.75mm
9.5 7.5 parts of 11.5 parts of 13.2～16mm of～13.2mm
7.5 parts of 16～19mm
Before using the present invention, at first want close traffic, promptly seal in Reparation of Bituminous Pavement rut highway section; Again the disease except that rut that occurs is handled as the position of cheating groove etc.; Emulsified bitumen slurry mixture is mixed and stirred the special machinery that paves demarcate, determine various material mixture ratio controlled variable; Gathering materials of preparing by different-grain diameter component and weight part requirement thereof, emulsified bitumen, water, additive (if desired) are all put into emulsified bitumen slurry mixture and mixed and stirred the special machinery that paves, pave while stirring then, carry out disposable individual layer and pave, paving thickness is 20mm; Repairing pave uneven place and with the seam crossing on former road surface; Carry out initial stage health and examination at last.
By gathering materials and the bituminous proportioning of above-mentioned different-grain diameter component and weight part thereof, the place compares with the little table of existing double-deck MS-3 type, the present invention adjusts on particle diameter that gathers materials and corresponding weight part, gather materials is to be fine rock material below the 2.36mm by particle diameter, particle diameter is the middle rubble material of 2.36～4.75mm, particle diameter is the rubble material of 4.75～13.2mm, particle diameter be 13.2～19mm super rubble material by a certain percentage scope be mixed, wherein Zui Da building stones particle diameter is 19mm, in pavement structure, play main supporting role, aggregate grading is more reasonable, the wedge that effectively overcomes between the building stones particle squeezes power, stressed reasonable between the building stones, avoid the road surface protuberance and sinking to take place in stressed back, improve rutting resistance, no longer repeated rut; The anti-supporting capacity enhancing in thin pulp table place also has good high temperature resistant property; Helping thin pulp table place and repair the simplification of rut technology, is the disposable repairing of close traffic of rut realization of 20mm to the same highway section degree of depth promptly, obviously shortens pavement track and repairs the duration; This grating of gathering materials, because the use of super rubble material can obviously reduce corresponding cost, the shortening of duration also is the major cause that reduces construction cost.The present invention has also carried out corresponding adjustment on the pitch and the proportioning of gathering materials.The little table of existing double-deck MS-3 type place, pitch accounts for the total weight percent of gathering materials and reaches 6.5～9.0%, is 5.0～7.0% and pitch of the present invention accounts for the total weight percent of gathering materials, and can effectively reduce raw materials cost.
