Background technology
The highway overwhelming majority that China builds all is to use bituminous paving, and the service condition on most of road surface is preferable, but Still be no lack of some new highways due to overload of vehicle, design unreasonable, quality control on construction it is not in place, it is undue rob work overwork with And the influence of each side factor such as weather conditions, after highway is open to the traffic occurred as soon as in several leading year rut, pit, crack, The different degrees of earlier period damage such as bag, bellding is gathered around, causes Pavement Condition to reduce, influence traffic safety.Therefore, it is how right Bituminous paving takes timely preventive maintenance, suppresses the further deterioration of the diseases such as crack, rut, pit, prevents road surface from going out Existing structural destruction, keeps good pavement performance, and the problem of prolonging service life of pavement gets growing concern for, also into It is one of domestic and international road engineering circle important research direction.
Preventive maintenance is exactly for the service level for keeping road surface good, the further development for delaying pavement disease, on road surface not Before recurring structure destruction, for the different diseases that road surface occurs, corresponding technical measures are taken, to improve the function on road surface Situation.Road pavement carries out preventive maintenance, can not only greatly promote performance, the prolonging service life of pavement on road surface, moreover it is possible to A large amount of human and material resources and financial resources spent on pavement maintenance are saved, therefore bituminous paving precuring technology has obtained more and more extensive Popularization and application.
The precuring protective material that China uses at present is mainly emulsified asphalt and modified emulsifying asphalt etc..These precuring protective materials are main By its highly filled pointing and road surfaces are bonded in, so that the permeability rate on road surface is reduced to zero or as far as possible close to zero, and The standard of Moisture Damage is prevented in this, as evaluation.But on actual pavement performance, this method that pavement seepage rate is reduced to zero Not fully agree with reality, because this method will be easier to cause the water smoke of rainy day, water drift problem, influence driving sight distance, increase Reflective after heavy rain, these will all directly affect traffic safety.For simultaneously for drainage pavement, this kind of conserving material is by road surface Seepage rate vanishing, water can not rapidly drain from road surface, just lose the traffic safety of drainage pavement and the advantage of reduction noise. In addition, traditional coal
Tar or emulsified asphalt preventive maintenance material also there are problems that it is following these:
(1) such material road pavement antiskid performance impact is larger, it is necessary to extra spill sand or addition sand to increase skin-friction force;
(2) because Material Physics is bonded in surface, do not permeate, therefore can not effectively suppress fracture propagation, the crack of covering is quickly Can display;
(3) material contains excessive oil, can be evaporated under surface layer exposure, causes summer road surface bellding phenomenon;
(4) coating formed after these materials applications rolls abrasion and takes away and can quickly form white rut problem by wheel;
(5) material itself is not durable, and performance degradation is fast.
The content of the invention
For above-mentioned the deficiencies in the prior art, make the invention provides a kind of performance that can greatly promote road surface, extension road surface With the life-span, moreover it is possible to the bituminous paving precuring construction method of the cost that uses manpower and material resources sparingly.
To achieve these goals, the invention provides a kind of bituminous paving precuring construction method, comprise the following steps:
(1) close traffic:Contacted with traffic police, road administration department or other relevant units before construction, it is common to formulate construction period friendship Logical measure of control, construction area need to be closed, and forbid personnel and vehicle to enter;
(2) treatment on road surface:For old road surface, first former road surface is thoroughly cleaned, dust out, dirt and residue; For newly-built bituminous highway, to treat that bituminous paving top layer did not had the greasy dirt for focusing mostly on just to construct, it is under normal circumstances, cold mixed Needed to wait for 1 month after asphalt laying, needed to wait for 1-3 month after the mixed asphalt laying of heat;
(3) construct:After the completion of former road cleaning, you can carry out the coating or spread construction of preventive maintenance agent;During construction, Coating or spread need uniform, even application one time, and average coverage rate is 3.5-4m2/kg, aging or well damage area Domain can suitably increase a construction, should be after that can be carried out after first pass formation level surface drying, in normal condition during second time construction Under, twice interval time of construction was controlled within 1 hour;
(4) conserve:After preventive maintenance agent construction, 2h~4h ability open to traffic is typically needed, now, any car need to be forbidden And pedestrian enter.
Used as the preferred of above-mentioned technical proposal, the preventive maintenance agent can not construct in rainy day or greasy weather, after construction in 1 hour Avoid drenching with rain, if being drenched with rain in 1 hour after construction, should suitably be filled spray depending on solidification situation, preventive maintenance agent should be avoided at 0 DEG C Below or pavement temperature is constructed higher than in the case of 40 DEG C, should select to be constructed when early morning or dusk during summer.
The beneficial effects of the invention are as follows:The present invention is for the service level for keeping road surface good, the further hair for delaying pavement disease Exhibition, before the non-recurring structure destruction in road surface, for the different diseases that road surface occurs, takes corresponding technical measures, to change The function status on kind road surface.Road pavement carries out preventive maintenance, and can not only greatly promote the performance on road surface, extension road surface makes With the life-span, moreover it is possible to save a large amount of human and material resources and financial resources spent on pavement maintenance, therefore bituminous paving precuring technology is obtained More and more extensive popularization and application.
