Abstract
A pavement repairing method includes the following steps: 1) preparation of a pavement repairing material: employing building glue including the following components, by weight, 10-15 kg of polyethylene, 10-15 kg of propylene resin, 0.75-1.25 kg of polypropionamide, 0.05-0.1 kg of tributyl phosphate, and 90-110 kg of water, adding water to the building glue and pouring the mixture into an ash barrel, stirring the mixture, and adding a proper amount of cement with stirring to prepare the pavement repairing material; 2) sweeping a pavement section with pitted surface, sand generation and cracking with a broom, blowing the pavement with a blower, washing the pavement with clean water and allowing the pavement to stand for air-drying the pavement; 3) when the cleaned pavement is in a slightly wet status, pouring the pavement repairing material on positions required to be treated on the pavement, and plastering the surface with a plastering knife; and 4) arranging barriers to protect the pavement until the pavement is solidified and hardened. The pavement repairing material is strong in adhesion force. The constructed pavement is anti-wear. The construction method is quick and reliable, is excellent in economic and social benefit and is suitable for pavement construction.
Description
Technical field
The present invention relates to road construction construction, furthermore, relate to a kind of method for repairing road surface.
Background technology
Highway pavement uses cement concrete pavement mostly, cement concrete pavement has advantage that is firm, wear-resisting, long service life, but due to long-term overload operation and natural cause impact, cement concrete pavement can produce the phenomenons such as pitted skin, founding, cracking, structure and the intensity on road surface are damaged, and repair will have a strong impact on traffic if do not made the best use of time.For solving this technical barrier of reparation of rigid pavement, many patented technologies are proposed, as CN2001110009767.7 " morning of cement concrete pavement reparation leads to concrete by force soon "; CN200910227529.6 " cement concrete road surface repairing material " etc., have certain effect, but also have its imperfection part, and people wish the better method for repairing road surface of a kind of repairing effect.
Existing method for repairing road surface, obviously has defect and exists, and need to be improved.Improving of the above-mentioned defect of thoughts of the present invention is that spy concentrates on studies and coordinates repetition test, finally proposes a kind of reasonable in design and effectively improve the invention of above-mentioned defect.Through retrieval, there is no relevant report.
Summary of the invention
The object of the invention is to the defect overcoming prior art, simple, practical, effective a kind of method for repairing road surface is provided, with the structure of redeck and its intensity of increase, make convenient and quick construction reliable, greatly save construction expense.
A kind of method for repairing road surface of the present invention, comprises the following steps:
(1), first cement concrete pavement repair materials is obtained: the gluewater in use for construction of employing is commercially available, it is made up of the raw material of following weight proportioning, and the weight quota of often kind of raw material is respectively: polyethylene 20 ~ 30 jin, poly-third resin 20 ~ 30 jin, poly-propionamide 1.5 ~ 2.5 jin, tbp 0.1 ~ 0.2 jin, 180 ~ 220 jin, water; Added water by above-mentioned gluewater in use for construction, successively pour in ash bucket by weight 1:1, stir, then add appropriate cement mixing and make cement slurry, namely it is a kind of cement concrete pavement repair materials;
(2), by the section of the pitted skin of rigid pavement, founding, cracking first with broom cleaning, removing impurity dust, more carefully blow off particle dust with hair-dryer, then scour without sediment motion is used, clean and need repair section, then blow away unnecessary moisture with hair-dryer, treat that section is air-dry;
(3), pending clean road surface is micro-moisture state, obtained cement concrete pavement repair materials is poured on need process place on road surface, wipes one's face, make new evenness of road surface bright and clean with the mud palm;
(4), protection 24 hours of placing obstacles (during temperature height, the time can shorten, summer can 8 hours), road surface solidification is stiff can be open to traffic.
This method construction should carried out without snow weather without rain, and temperature should lower than 5 DEG C.The gluewater in use for construction that this method adopts is commercially available, but this product also locates the development stage.The cement concrete road surface repairing material caking property that this method is made is strong, resistance to wear in the road surface constructed, construction method is fast reliable, it is short to repair the time used, very little to traffic impact, road structure good stability, shortens the construction cycle greatly, operability is very strong, has good economic benefit and social benefit.
The inventive method is applicable to road construction construction application.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
embodiment:
There is pitted skin, founding in certain rigid pavement, speedway one section, adopt the inventive method reparation, the method comprises the following steps:
The first step is obtained cement concrete road surface repairing material: the gluewater in use for construction of employing is commercially available, it is made up of the raw material of following weight proportioning, and the weight quota of often kind of raw material is respectively: polyethylene 25 jin, poly-third resin 25 jin, poly-propionamide 2 jin, tbp 0.1 jin, 180 ~ 220 jin, water; Added water by above-mentioned gluewater in use for construction, successively pour in ash bucket by weight 1:1, stir, then put into appropriate cement mixing and make cement slurry, namely it is a kind of cement concrete road surface repairing material;
The section of the pitted skin of rigid pavement, founding first with broom cleaning, is removed impurity dust, more carefully blows off particle dust with hair-dryer, then use scour without sediment motion, clean and need repair section, then blow away unnecessary moisture with hair-dryer, treat that section is air-dry by second step;
3rd step is pending clean road surface is micro-moisture state, the cement concrete road surface repairing material made is poured on need process place on road surface, wipes one's face, make new evenness of road surface bright and clean with the mud palm;
4th step is protection of placing obstacles, and because being summer at that time, protection 8 hours of placing obstacles, road surface solidification is stiff can be open to traffic.
The new road surface of this method construction has used more than 2 years and has still stood intact.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
