Description
Technical field
The present invention relates to building material field, be specifically related to a kind of road surface and crack material for quickly repairing and preparation method thereof that can use in cold district.
Background technology
Bituminous concrete pavement is the main paving type of current countries in the world high-grade highway.Bituminous concrete pavement has surfacing, without seam, vibrates the advantages such as little, noise is low, it is comfortable to drive a vehicle, maintenance is convenient.But by the impact of the quality of road asphalt own, in the intensity of pitch on road surface, stability etc. of China, temperature influence is larger, road surface is easy to destroy.
For large-area damaged road surface, traditional repair materials mainly hot-mix asphalt mixture, but there is the defect that pollution is high, cost is large in this repair materials, in addition, the impact of hot-mix asphalt mixture climate condition is comparatively large, in the cold season of unsuitable compacting because temperature is lower, should not construct.Using more is in recent years asphalt cold repairing repair materials, as Emulsified Asphalt Mixture.Asphalt cold repairing repair materials overcomes the defect that hot-mix asphalt mixture low temperature should not be constructed, but when using cold repairing asphalt mixture redeck, the effect of enhancing just can be played after needing equal solvent to evaporate completely, so cold repairing asphalt mixture exist initial strength low, strengthen shortcoming slowly, the object that quick reparation is open to traffic fast can not be reached, larger to traffic impact.
For the top layer class disease of cement concrete pavement, the traditional method of highway maintenance department adopts asphalt to carry out local route repair or overall cover to it, although it is comparatively easy to construct, but because the rigidity of bi-material is inconsistent, the existence of the shearing between interface easily causes coming off of patching material and lost efficacy.Another kind of traditional method for repairing and mending is removed by the concrete of breakage, and making is not less than the normal concrete of original design strength grade again, and this repair mode mainly exists following problem: novel concrete shrinks comparatively old concrete and shrinks large, easily causes shrinkage cracking; (2) between new-old concrete due to reasons such as boundary defects, its mutual cohesive strength is low, all easily cause repair lost efficacy; (3) curing cycle is long, brings larger pressure to traffic operation.
Patching material for cement concrete cracks is generally flexible materials, as polyvinyl chloride (PVC) cement, pitch, rubber etc.These materials only can reach the effect in shutoff crack, can not supporting crack two wall thus can not be jointly stressed with both sides road deck as a whole, so crack can be caused to spread during pressure when vehicle fracture two wall has and expand; In addition, because the contraction of these materials and cement concrete material, swelling property differ greatly, cause easily be extruded its summer, the material be extruded comes off from original place under the effect of wheel, and when cold weather concrete panel shrinks, crack place produces larger space thus seam sealer inefficacy; Further, because flexible patching material and cement concrete pavement colour contrast are large, on road surface, form black line after perfusion, comparatively seriously affect the use properties on road surface.
Under the background of global energy dilemma, repair in road process and require save energy, economize on the use of funds, the cry of protection of the environment, decreasing pollution is more and more higher.Fast, early strong, energy-conservation material for road repair, and the novel material for quickly repairing had big area road surface, Lamina, crack repairing have general validity has very important application prospect and realistic meaning therefore.
Summary of the invention
The object of the present invention is to provide a kind of road surface and crack material for quickly repairing and preparation method thereof that can use in cold district.Which solve weak with old pavement cohesive force in background technology, the technical problem such as working procedure is complicated, long construction period, long impact curing cycle are open to traffic.
For reaching above-mentioned purpose, the concrete scheme that the present invention adopts is:
The road surface that can use in cold district and a crack material for quickly repairing, be made up of the raw material of following weight percents: metal oxide, one or more in aluminum oxide, magnesium oxide, ferric oxide, zinc oxide, total content is 5-55%; Phosphoric acid salt, one or more in dipotassium hydrogen phosphate, potassium primary phosphate, Secondary ammonium phosphate, primary ammonium phosphate, potassiumphosphate, ammonium phosphate, total content is 5-55%; Auxiliary agent, flyash, Sodium Tetraborate, trisodium phosphate, Sodium Silicofluoride, total content is 1-10%; Filamentary material, one or more in cotton fibre, glass fibre, bamboo fibers, carbon fiber, ceramic fiber, total content is 0.5-5%; Sand, one or more in Machine-made Sand, natural fine sand or natural coarse sand, total content is 30%-50%; Stone, 0-20%, by following proportions: the rubble of 5-10mm particle diameter: 10-30 part; The rubble of 11-16mm particle diameter: 20-30 part; Be less than the aggregate chips of 5mm particle diameter: 10-50 part; Water, total content is 5-50%.
Preparation method comprises the following steps:
(1) by formula rate by metal oxide, phosphoric acid salt, auxiliary agent, filamentary material, water, be uniformly mixed 1-3min.
(2) mixture (1) obtained and the sand of formula rate, stone are uniformly mixed 1-2min.
Beneficial effect of the present invention:
The present invention is a kind of can have following characteristic on the road surface of cold district use and crack material for quickly repairing:
1. material preparation and construction temperature scope wide: can low reach the condition of-10 degrees Celsius under use, both can warm up in south area use, also can use in north cold area.And whenever and wherever possible, seamed, have breakage to repair, can crackle preventing further destruction that road is produced in time.
2. greatly shorten and be open to traffic the time: repair materials self time of coagulation short (10 seconds-30 minutes adjustable), the object that can realize quickly repairing cement concrete pavement disease has been repaired in 0-4 hour and can be open to traffic.
3. good with concrete consistency: strong with pavement concrete substrate interface bonding force, within 1 day, bonding strength can reach 4MPa.
4. construction is convenient, economical: can stir spraying integration, drop into without the need to too much equipment labour cost.
5. suitability is strong: can be used for the large area repair of pitch and cement pavement, thin layer reparation and crack reparation etc., color can according to road surface color modulation, natural curing.
6. environmental protection is attractive in appearance: construction process noiseless and a large amount of dust, it also avoid the phenomenons such as the atmospheric pollution that conventional repair materials brings.
The form of construction work of this material is:
1. road surface cleaning: road surface scavenger to be repaired is carefully cleaned, the top layer of activity is thoroughly removed; If road surface has graticule, original graticule is removed by application line removing machine.
2. the preparation of repair materials and construction: repair materials is dropped into stirrer, stirs after 3-5 minute, mechanically spraying can be adopted and manually smear two kinds of modes and construct.
