Abstract
The invention discloses a fine surface treatment method for a double-layer spread type bituminous pavement and belongs to the related field of bituminous road maintenance and repair. The fine surface treatment method comprises the steps that (1) according to a base layer, after all components of epoxy asphalt binding materials are stirred evenly as required, the mixture is evenly sprayed to the bituminous pavement with certain pressure, and a layer of fine sand is synchronously and evenly spread; and (2) according to a surface layer, after the base layer is solidified, the surface of the base layer is covered with a layer in the mode of the step (1) to form a waterproof antiskid protective layer. According to the fine surface treatment method, the old bituminous pavement can be repaired fast, the antiskid capacity of the pavement and the road appearance are improved.
Description
Technical field
The present invention relates to asphalt pavement maintenance and repair association area, being specifically related to a kind of double-deck layer paving formula flexible pavement fine surface treatment method.
Background technology
Flexible pavement as the jointless continuous pavement of one, because having surfacing, drive a vehicle comfortable, wear-resisting, noise is low, short construction period, the advantage such as easy to maintenance, be widely applied in high-grade highway construction.
Due to the complexity of bituminous coat project itself, polytropy and the various reasons such as structure design and quality control on construction, add the factors such as the continuous increase of the traffic volume, the canalization of vehicle traveling, the aggravation of overload transportation and Moisture Damage, flexible pavement (or bridge deck pavement) is occurred earlier period damages such as crack in various degree, rut, surface are loose, hole groove, seriously reduce road surface (or bridge floor) functional performance.In order to administer the early disease that flexible pavement (or bridge floor) occurs, it is made again to recover the pavement performance of flexible pavement (or bridge floor), ensure the normal use of road, current most domestic area have employed corrective maintenance method, namely just process after disease occurs, the drawback of so easy appearance " headache doctor head, pin pain controls pin ", cause process effect to fall flat, overlapping investment is also larger.Simultaneously, fasten in the pass of maintenance of surface and maintenance, highway industry is due to the tendency of ubiquity " reconstruction is gently supported ", " supporting to build generation ", maintenance of surface just starts to keep in repair after usually waiting road surface (or bridge floor) to start to occur destruction, maintenance fund limited is like this mainly used in overhaul and even reconstructs and reproduce, the circumstances of the low output of awkward high investment that caused highway maintenance to be absorbed in, comes into the vicious circle of a vicious circle.
The huge pressure brought with maintenance financing gap is increased fast in order to effectively alleviate maintenance management workload, improve road network performance, except quickening Maintenance System and maintenance operation mechanism are reformed, strengthen outside the input of maintenance fund, also must change maintenance management guiding theory, change Maintain management mode, across-the-board regulation some traditional maintenance idea and usual practices, highway maintenance is changed to scientific maintenance by passive maintenance, by single maintenance, extensive maintenance is to compound, intensive maintenance changes, to carry out in an all-round way preventive maintenance, thus set up there is initiative, foresight and systematic highway maintenance work system.
Asphalt Pavement Maintenance Technology specification clear stipulaties, must carry out preventative, regular and periodically maintenance to flexible pavement.According to u s. state highway and transport NAB National Association 0f Broadcasters AASHTO road Standing Committee to the definition of preventive maintenance, preventive maintenance be a kind of take when pavement behavior is good to existing road system carry out planned, based on the maintenance strategy of Cost-Electiveness; Preventive maintenance, when not improving Pavement structural capacity, can postpone the damage on road surface, maintains or improves the existing train-passing through conditions in road surface.By to Expressway Implementing road surface preventive maintenance, energy is the small disease of redeck in time, prevent major injury, reduce moisture and enter road structure internal sabotage basic unit, ensure the globality of road structure, slow down the breakdown speed of road, correcting pavement such as cling property and non-load destroy, postpone expensive overhaul and reconstruction activities, thus extend the application life on road surface, keep the service state that road surface is good.
Along with the center of gravity of highway administration department from new highway to the transfer of maintaining public highway, road surface transform is also from the mode of maintenance priority ordered to supporting that maintenance strategy such as the preventive maintenance of cost effectiveness shifts.Therefore, research and development Expressway Pavement Preventional Curing new technology, implement road surface preventive maintenance be China's Expressway Development in the urgent need to.
In order to keep the kilter of Pavement Condition and extend its application life, different maintenance measures is adopted in each different phase of life cycle, the maintenance technology of employing science, becomes Recent study focus with the maintenance quality and reduction maintenance cost that ensure road surface.Such as at the early stage stage of development of road disease, joint filling, joint seal, mist sealing, slurry seal, micro-surface area, cape sealing, screening seal coat, rut are filled up, the technology such as thin overlay, ultra-thin wearing layer, superthin layer cover as emerged rapidly in large numbersBamboo shoots after a spring rain, start one preventive maintenance upsurge at home.But, through application for many years, the domestic technology such as cover, micro-surface area, overlay heated bitumen generally taked is limited to road elevation, durability, load-bearing, traffic pressure, cost and self can not adapts to the needs of modern urban road development to factors such as material, equipment requirement height at present, and steps down from the stage of history gradually.And mist sealing covers and its relevant substitute products are still subject to heat handful to a certain extent, but by reducing the reason such as former pavement skid resistance condition and durability deficiency after it uses, its extensive use still lacks of staying power.
So seek a kind of environmental protection, quick, effect is durable, can pavement skid resistance condition be improved and the new technology of relative inexpensiveness, with to occurring that the bad flexible pavement of the disease such as aging, pitted skin, loose, cracking, infiltration, polishing processes in time, prolongation Road Service Life is imperative.
Summary of the invention
The anti-slide performance decline occurred is for many years being used for solving flexible pavement, the problems such as road surface is aging, pitted skin, loose, cracking, infiltration, polishing, extend Road Service Life, the invention provides a kind of double-deck layer paving formula flexible pavement fine surface treatment method, reach fast quick-recovery function path and aesthetic road, and road maintenance cost can be reduced.
Object of the present invention is achieved through the following technical solutions:
A kind of double-deck layer paving formula flexible pavement fine surface treatment method, comprising step 1) bottom is after each for bituminous epoxy binding material component being stirred evenly on request, by its with certain pressure even application on flexible pavement, and synchronous evenly spreading layer of fine sand.Step 2) surface layer be until bottom solidification after form waterproof antiskid topping according to the mode of step 1) at its surface coverage one deck again.
Described bottom bituminous epoxy binding material used is epoxy modified asphalt glue, and its quantity for spray controls at 0.3-0.4kg/ ㎡, and fine sand spreading amount is 0.1 ~ 0.3kg/ ㎡.
Described surface layer bituminous epoxy binding material used is epoxy modified asphalt glue, and its quantity for spray controls at 0.2-0.3kg/ ㎡, and fine sand spreading amount is 0.5 ~ 1.0kg/ ㎡.
