Abstract
The present invention relates to a method for reconditioning a road surface by using asphalt rubber, which comprises the following steps: dust and impurities in cracks of an asphalt road surface to be repaired are removed; a prepared hot asphalt-rubber sealing/crack filling material is sprayed on the road surface; the aggregate with the same grain diameter is added into the sprayed hot asphalt-rubber combined material; a heavy air-pressure road roller is used for rolling the road surface. If the road surface to be repaired is not flat or is deformed, a level plane needs to be built by the traditional asphalt concrete before the hot asphalt-rubber combined material is sprayed.
Description
Technical field
The present invention relates to utilize the method on asphalt rubber finishing road surface, particularly utilize asphalt rubber to fill out the envelope crack again and spray the method on the road surface that needs finishing.
Background technology
Pitch and cement concrete pavement various cracks can occur through after a while use, and aging and disrepair phenomenon take place.At this moment, need road pavement to repair and safeguard, to guarantee evenness of road surface.
Usually, the flexible pavement of breakage is repaired the method that is adopted be, smash damaged flexible pavement earlier, more broken supercrust (pitch fragment) is removed this discontinuous method from the road surface and carry out lentamente.Then, aspect impaired under original blacktop is transformed and again compacting until meeting the requirements.In addition, at present the processing of damaged aspect is comprised that also cold bundle method removes damaged asphalt surface course.Said process is not only time-consuming, consumption wealth, and can produce the available old concrete that pile up like a mountain.
Summary of the invention
An object of the present invention is to provide a kind of new asphalt rubber that utilizes and fill out the method for road closure face.
A method according to the present present invention comprises the following steps: to remove dust and the foreign material in the crack that needs the flexible pavement repaired; Preparation asphalt rubber joint seal/joint sealing material; Described asphalt rubber joint seal/joint sealing material is heated to correct temperature; With remaining on described asphalt rubber joint seal/joint sealing material sealing of 190-200 ℃ or filling up described crack.
Another kind of method according to the present invention comprises the following steps: with asphalt rubber joint seal/joint sealing material sealing or fills up the asphalt pavement crack of required repairing or the junction of rigid pavement; The preparation asphalt rubber binder; Spray the road surface with the above-mentioned asphalt rubber binder for preparing that maintains 195-210 ℃; In the good heated bitumen rubber binder of described sprinkling, add gathering materials with particle diameter; Roll with heavy air pressure road roller.
Utilize method of the present invention, can prevent that sealing infiltrates old pavement crack, thereby prevent that supercrust from further damaging.Can save greatly simultaneously and transform damaged used time and the construction costs in road surface, reduce when utilizing the prior art transformation to repair damaged road surface the influence of traffic and the time of blocked road.In addition, keep road surface elasticity, greatly reduced the road surface ageing time, reduced maintenance number of times and time, saved cost greatly.
The specific embodiment
Use or other reason owing to long-time, various cracks usually appear in the supercrust that is made of pitch or cement concrete, take place damaged.
For the crack of flexible pavement or the junction of rigid pavement, at first to remove wherein dust or foreign material etc.Removing work can be by hand or mechanical mode carry out.Because size, the degree of depth and the out-of-shape in crack, the most handy mechanical system is finished.About 250 ℃ hot gas that can use instrument such as hot-air syringe to produce blows out the dust in the crack, rubble or foreign material etc.Also can use other known equipment or instrument to remove.
After dust out, the foreign material etc., seal or fill asphalt pavement crack or the junction, rigid pavement that needs repairing with a kind of special asphalt rubber crack sealer/joint sealing material.This asphalt rubber crack sealer/joint sealing material utilizes in pitch, oil plant and the junked tire and extracts and be processed into brand-new technology, has very high softening point.
When asphalt pavement crack or junction, rigid pavement filled bitumen rubber crack sealer/joint sealing material, asphalt rubber crack sealer/joint sealing material is reached or remain on correct temperature, promptly about 190 ℃-200 ℃, to guarantee to penetrate and fill the crack.High temperature can also guarantee the bonding of asphalt rubber crack sealer/joint sealing material and crack perisporium.For this reason, can adopt special-purpose mobile unit heating and storage asphalt rubber crack sealer/joint sealing material.Because the scrambling in crack, preferably asphalt rubber crack sealer/joint sealing material is placed in the mobile unit that can be heated correct temperature, be injected into crack or junction with hand-held gate spool, to reach the purpose that the crack is fully filled.
The Uneven road of Xiu Buing or deform if desired should be after above-mentioned filling be finished, with traditional bituminous concrete at above-mentioned Uneven road place or the place of deforming build a level surface so that the road surface keeps is smooth.
On level surface, spray special heated bitumen rubber binder then.This asphalt rubber binder is fully to be stirred by crumb and pitch to form.Stirring should at high temperature be carried out to guarantee its uniformity.
Sprinkling can utilize mechanical system to carry out.Should be between 195 ℃-210 ℃ during sprinkling with the temperature maintenance of asphalt rubber binder.
After spraying asphalt rubber binder on the road surface, directly in heated bitumen rubber binder, add single-sizeaggregat.Normally 6.7 millimeters of the sizes of gathering materials, 9.5 millimeters, 13.2 millimeters, 16.0 millimeters and 19.0 millimeters.The density of gathering materials is determined according to factors such as concrete road conditions, weathers.
Then, roll, make the road surface reach the use standard with heavy pneumatic road roller road pavement.
More than by embodiment the present invention has been described, but the present invention is not limited thereto.Those skilled in the art can make different modifications to the present invention under the situation that does not break away from spirit of the present invention.All modifications all falls within the scope of the present invention.
