And then carry out multiple pressure after first pressing, the object of multiple pressure makes compound closely knit, stable, shaping, and generally adopt heavy road roller (being generally rubber-tyred roller), number of rolling is determined through pressure testing, and is no less than 4-6 time, till meeting the requirements of degree of compaction.
The object of final pressure eliminates the wheelmark of rolling wheel generation, general employing steel cylinder road roller.
Above-mentioned the deficiencies in the prior art part is:
1, first pressing adopts steel wheel rolling road surface, sprinkles water in a large number simultaneously, causes temperature leak;
When 2, adopting tire to carry out multiple pressure, the temperature of bituminous mixture is lower, easily causes bituminous mixture to be bonded in tyre tread; Need to adopt diesel oil cleaning tire, waste time and energy and waste diesel oil;
3, during first pressing, steel wheel can cause the passing of bituminous mixture, and the place of turning back easily forms the horizontal ridge, causes surface evenness inadequate;
4, there are vibrations during steel wheel rolling road surface, cause road surface basic forming, during pressure, the amplitude of the rubbing effect that tire brings is less again, cannot play the rubbing effect of tire, cause the compactness on road surface not meet designing requirement;
When 5, pressing again, the temperature of bituminous mixture is lower, and tire print is not easily eliminated;
When 6, pressing again, the temperature of bituminous mixture is lower, not easily on road surface, forms sealing oil film.
Described the deficiencies in the prior art, cause the quality of existing asphalt highway often undesirable, the application life of highway is shorter.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of step simple, be suitable for guaranteeing road quality and application life longer asphalt highway construction method.
In order to solve the problems of the technologies described above, the invention provides a kind of construction method of asphalt highway, it comprises: adopt rubber-tyred roller to carry out first pressing, that is: rubber-tyred roller rolls 2-3 time immediately following after paver, and in roller compaction process, pavement temperature is 120-150 DEG C; Steel roller is adopted to complete final pressure after first pressing, to eliminate the tire print on road surface.When first pressing, by adjusting the mode of rubber-tyred roller water tank volume or counterweight, the compacting weight of each tire of described rubber-tyred roller is made to be 1.8-2 ton.For preventing tire sizing, the pavement temperature when adopting rubber-tyred roller to complete first pressing more than 100 DEG C, with protected tyre sizing.
Technique scheme of the present invention has the following advantages compared to existing technology: in the construction method of (1) asphalt highway of the present invention, temperature is paved after on road surface by paver higher than the bituminous mixture of 130 DEG C, rubber-tyred roller is adopted to carry out first pressing immediately, because temperature of charge is now between 120-150 DEG C, the amplitude that road surface is suitable for being crumpled by tire is larger, the weight of the rubber-tyred roller therefore adopted can suitably reduce, the compacting weight of each tire is that 1.8-2 ton gets final product (the tire compacting weight of rubber-tyred roller of the prior art is generally more than 2 tons), rolling layer also only needs 2-3 time, can meet the designing requirement of road surface compactness.Wherein, temperature determines that quality is rolled on road surface.During tire first pressing, temperature of charge is higher, so the pitch in material easily forms thicker Seal Oil rete on road surface, thus can anti-sealing, mud and air invade, and is beneficial to and prevents road surface Moisture Damage, improves pavement durability; (2) in the present invention, adopt tire first pressing, the not sticky tire of bituminous mixture, tire sizing is only relevant with temperature, as long as the temperature of bituminous mixture is more than 100 DEG C, tire rolls would not sizing.And in the prior art, when adopting tire to carry out multiple pressure step, to tire watering, cause the temperature of bituminous mixture at 80-100 DEG C, now adopt tire to press again, be easy to sizing.(3) in the present invention, during tire first pressing, temperature of charge is higher, not easily occurs that material is passed, cracking and the phenomenon such as segregation during rolled asphalt compound, and turns back and a little do not swell, so not easily formation road surface Heng Geng, surface evenness is better.Rubber-tyred roller is in roller compaction process, and tire tread road pavement has rubbing effect, and on road surface, form closeer fine rule, line more carefully, closeer, surface evenness, compactness are better.Road surface after tire first pressing, without the need to the aspect of repairing, road surface not moisture (because without watering process).In addition, tire first pressing is suitable for the cataclasm horizontal ridge because of paver leveling generation, also has and eliminates the spot of generation that paves, the effect of pit, make road surface more smooth, attractive in appearance, is suitable for reducing related work amount.Pitch can be crumpled to top layer and form oil film by the kneading action of rubber-tyred roller, fills up space, top layer, and to reach sealing top layer, anti-sealing, mud and air invade.Be conducive to preventing road surface Moisture Damage, improve pavement durability.(4) the present invention adopts tire to complete first pressing, is suitable for simplifying construction sequence, reducing road surface rolling layer, so significantly can reduce construction cost, quickening construction progress, is beneficial to raising pavement quality simultaneously.
