Abstract
The invention discloses an anti-icing anti-sliding asphalt pavement micro-surfacing material. The anti-icing anti-sliding asphalt pavement micro-surfacing material is characterized by consisting of the following components: 70%-85% of gravels, 5%-12% of modified emulsified asphalt, 1%-3% of mineral powder and 1%-2% of deicing salt materials. By using the anti-icing anti-sliding asphalt pavement micro-surfacing material, the icing time of an asphalt pavement can be effectively delayed, the road traffic accidents under the cold weather conditions can be reduced, and the anti-icing anti-sliding asphalt pavement micro-surfacing material has obvious practicability and also has significant social benefits and economical benefits simultaneously.
Description
Technical field
The invention belongs to functional form flexible pavement technical field.
Background technology
China region is wide, and north-south climate differs greatly, and the extreme climate frequency of occurrences in various places increases in recent years in addition, and road surface accumulated snow ice formation issues is comparatively common.When particularly just having entered winter and spring, road surface has been very easy to thin ice and has produced.The traffic capacity and the traffic safety of the icing meeting of the accumulated snow of road surface serious harm road, people's safety of life and property can't effectively be ensured.
Snowfall, freezing directly to cause the decline of road surface non-skid property, thereby easily cause traffic accident.Related data shows that the friction factor of normal flexible pavement is approximately 0.6, and when having accumulated snow on the road surface, friction factor is 0.2, is reduced to 1/3rd of normal flexible pavement, when the road surface existence is frozen, friction factor is 0.15, is reduced to 1/4th of normal flexible pavement.Therefore, when automobile travelled on the road surface that accumulated snow freezes, the road surface can't provide enough frictional force, and tire skids easily, and the incessantly car that causes stopping causes traffic accident such as knock into the back easily.
At present, for the traffic accident that reduces the snowfall in winter, freezes and cause, each highway administration department mainly takes the method for close traffic.As, riverine, the southern area of Jiangsu Province in Jiangsu on January 26th, 2008 suffers moderate snowfall, and heavy snow appears in the part, causes the sealing at a high speed of the domestic part in Jiangsu, and Nanjing periphery high speed is totally-enclosed.The snowfall in February, 2011 causes 12 high speeds of 5 provinces such as Zhejiang, Jiangsu to be obstructed because the snow mist is current.
The sealing of speedway and ordinary road not only easily cause traffic accident because the traffic capacity that ice and snow causes descends, and also bring enormous economic loss simultaneously.Development deicing type flexible pavement technology not only helps to reduce the traffic accident of ice and snow weather, can also effectively ensure the highway capacity under the hazard weather condition simultaneously.This technology has obvious practicability, also has remarkable social benefit and economic benefit simultaneously.
Summary of the invention
Goal of the invention: the object of the present invention is to provide the little table of a kind of anti-icing antiskid flexible pavement place material, use this material can effectively delay the icing time on road surface, reduce the road traffic accident under the cold weather conditions.
Technical scheme: for solving the problems of the technologies described above, the invention provides the little table of a kind of anti-icing antiskid flexible pavement place material, this little table place material consists of: rubble 70%～85%, modified emulsifying asphalt 5%～12%, breeze 1%～3%, deicer salts material 1%～2%.
Preferably, the deicer salts material is made up of deicer salts and deicer salts additive; The composition of deicer salts is sodium chloride, accounts for 60%～80%% of gross mass, and the composition of deicer salts additive is calcium oxide, silica, di-iron trioxide and alundum (Al.
Beneficial effect: beneficial effect was after the present invention adopted technique scheme: use this technology can effectively delay the icing time of flexible pavement, reduce the road traffic accident under the cold weather conditions, have obvious practicability, also have remarkable social benefit and economic benefit simultaneously.
The specific embodiment
Below the present invention will be further described.
The little table of anti-icing antiskid flexible pavement provided by the invention place material, this little table place material consists of: rubble 70%～85%, modified emulsifying asphalt 5%～12%, breeze 1%～3%, deicer salts 1%～2%.
The composition of deicer salts is sodium chloride, accounts for 60%～80%% of gross mass, and the composition of deicer salts additive is calcium oxide, silica, di-iron trioxide and alundum (Al.
1. the mineral aggregate gradation of deicing type micro-surfacing mixture
Table 1 is the mineral aggregate gradation of deicing type micro-surfacing mixture.Select corresponding grating at the actual conditions in concrete highway section.
The mineral aggregate gradation of table 1 deicing type micro-surfacing mixture
2. deicer salts determination of ratio
Use the deicer salts equal-volume to substitute the part breeze, alternative ratio is 50%～80%.Determine the optimum mix amount of deicer salts according to the wet wheel abrasion test of little table place and loading wheel test and deicing effect test.
3. the preparation of construction of deicing type micro-surfacing mixture
Foreign material on the cleaning road surface according to sequence of construction, reach the job location with the seal machine of filling compound, adjust paving width and thickness.
4. paving of deicing type micro-surfacing mixture
Open the discharging valve, start the seal machine, low-speed forward paves, and speed is generally 1.5～3.0km/h.
5. initial curing and rubber tire roll
In the curing time, use pneumatic-tired rollers slowly to roll the maintenance highway section in the early stage, improve the seal adhesion stress, shorten the open to traffic time.
Use the present invention can effectively delay the icing time of flexible pavement, reduce the road traffic accident under the cold weather conditions, have obvious practicability, also have remarkable social benefit and economic benefit simultaneously.
Used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of claim of the present invention.
