Abstract
The invention discloses a patching material for potholes of an anti-icing road surface and a preparation method of the patching material, and belongs to the technical field of building materials. The patching material for the potholes comprises the following components in parts by weight: 88.5-89.5 parts of aggregate, 5-5.5 parts of cold-patch asphalt liquid and 5.5-6 parts of anti-icing agent Verglimit-260, wherein the cold-patch asphalt liquid comprises the following components in parts by weight: 77-80 parts of asphalt, 17-20 parts of diesel oil and 2.5-3 parts of cold-patch agent Ad-here 260L. The preparation method comprises the following steps: 1) stirring the asphalt while heating, and stopping heating when the asphalt reaches 165-175 DEG C, adding the diesel oil and the cold-patch agent in sequence, stirring uniformly, and obtaining the cold-patch asphalt liquid, (2) mixing the asphalt liquid with the aggregate uniformly, keeping on stirring, adding the anti-icing agent at 10-15 seconds before the stirring is finished, and discharging after the stirring is finished. The patching material can be stored at a room temperature for a long time after packaged in small bags, can be taken at any time for use and is convenient to use; the anti-icing temperature of the patching material can reach subzero 20 DEG C; the anti-icing performance can be comparable to that of the original anti-icing road surface; the traffic can be opened after patching; and an unimpeded road is ensured.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of freezing road surface pit repairing material, also relate to the preparation method of this material simultaneously.
Background technology
Highway transportation network is the important infrastructure ensureing that passenger traffic is quick and logistics is unobstructed.At present, highway in China construction has entered the on national network stage, and motorway has become the trunk main of highway network system.But, the security of highway communication and the easy climate impact of conveying efficiency.Especially in cold season, road surface, once freeze, not only can make the security of highway communication and conveying efficiency have a greatly reduced quality, and also road pavement (bridge floor) and attached structure can cause major injury.When time icy on road, pavement skid resistance condition significantly reduces, and automobile easily skids out of control, even needs close traffic time serious, causes traffic paralysis.2008, Hunan ice disaster once caused traffic paralysis, had had a strong impact on the normal operation of local economy activity.Along with the progress of science and technology, freezing road surface occurs gradually in China's motorway, and constantly plays its freezing performance.
The same with conventional road surface, freezing road surface is rolled with under various effect of natural environment at vehicle, also can produce disease such as hole groove, crack etc.Timely pot holes mend can stop hole groove area to expand effectively, is conducive to prolonging service life of pavement, saves maintenance costs.But for freezing road surface, still lack a kind of suitable patching material at present: if use the hot-laid mixture identical with former ground surface material, just need during construction to start mixing station.The asphalt amount once produced of blending station is comparatively large, and the demand of general pit repairing to compound is less, and residue compound cannot long storage time, will certainly cause great waste, raise repairing cost.In addition, the transport of hot-laid mixture is also very inconvenient.Although conventional cold-repairing material can solve the storage problem of hot-laid mixture, the problem that repairing face froze in cold season can not be solved.In other words, repair the hole groove on freezing road surface according to conventional cold-repairing material, freeze to ice and snow face of repairing in season, local, road surface cling property can be caused poor, affect traffic safety all the better.Further, when road surface is by snow and ice cover, repairs position and not easily determine, ice-melt cannot be carried out by local salting.Visible, solve local, road surface slippage problems and there is great difficulty.
Summary of the invention
Object of the present invention aims to provide a kind of freezing road surface pit repairing material, additionally provides the preparation method of this material simultaneously.
Based on above-mentioned purpose, the technical scheme that the present invention takes is: a kind of freezing road surface pit repairing material, it consists of by weight: gather materials 88.5 ~ 89.5 parts, asphalt cold repairing liquid 5 ~ 5.5 parts, deicing agent Verglimit-260 5.5 ~ 6 parts, wherein the weight of asphalt cold repairing liquid consists of: pitch 77 ~ 80 parts, diesel oil 17 ~ 20 parts, cold-patch agent Ad-here 260L 2.5 ~ 3 parts.
Described diesel oil is-10# diesel oil.
Described pitch is SBS modifying asphalt.
Described weight of gathering materials consists of: the building stones 14 ~ 16 parts of particle diameter 9.5 ~ 16.5mm, the building stones 21 ~ 28 parts of particle diameter 6 ~ 9.5mm, the building stones 21 ~ 25 parts of particle diameter 2.75 ~ 6mm, particle diameter are less than building stones 30 ~ 38 parts, the breeze 2 parts of 2.75mm.
The preparation method of described freezing road surface pit repairing material, step is: 1) heat while stirring pitch, stops heating when asphalt temperature reaches 165 DEG C ~ 175 DEG C, adds diesel oil, cold-patch agent stirring successively, obtains asphalt cold repairing liquid; 2) asphalt cold repairing liquid and aggregate blending is even, continue to stir and also within 10 ~ 15 seconds before stirring terminates, add deicing agent, stir and terminate rear discharging.
At present, what freezing road surface adopted when laying is all hot-laid mixtures, needs to start mixing station, and single output is very large, and repair hole, freezing road surface groove according to this pattern, material once cannots be used up and can cause great waste, and directly cost is repaired in impact.And existing hole groove cold-repairing material does not possess freezing performance, use rear surface to freeze and local, road surface can be caused to skid, traffic safety cannot ensure.Salting deicing not only can corrode bridge pavement, contaminate environment, and under snow and ice cover, the ice forming locations on road surface is also difficult to determine.
Freezing road surface provided by the invention pit repairing material can solve the problem just.The freezing temperature of this patching material is-20 DEG C, and face of repairing is also not-easy-to-freeze for season at ice and snow, can keep same freezing performance with original freezing road surface.This pit repairing material, as the anti-icing shaped material of active, can substitute salting deicing completely, effectively can avoid the detrimentally affects such as the pollution because salting causes, erosion.
After packing, freezing road surface of the present invention pit repairing material at normal temperatures can long-term storage, and the safe storage phase is not less than 12 months; Pouch-packaged, convenient to use, repair and completely get final product open to traffic, fully meet the requirement ensureing the coast is clear.
