Description
One, technical field
The present invention relates to a kind of novel deck paving waterproof system, and material, preparation and the pavement construction method of waterproof system are provided.
Two, background technology
Domestic present most of engineering is not only considered waterproof effect by the wearing layer design to bridge deck pavement, causing water to infiltrate mating formation to form power betwixt between layer and the bridge deck washes away, or at cold district generation freeze-thaw damage, the layer that causes mating formation breaks away from bridge deck, early damage appears in deck paving, has not only had a strong impact on the result of use of high-grade highway, causes a hidden trouble to traffic safety, influence the current environment of highway, increase the maintenance cost; On the other hand, water infiltrates in bridge deck and the bridge construction, causes the too early corrosion of reinforcing bar of structure inner panel, girder construction, concrete surface charing and corrosion, the concrete supporting capacity descends, and causes the bearing capacity of whole bridge construction to descend, and bridge durability will be affected.Foreign experience is told us, as if effective protection of ignoring bridge construction, in the use of the later stage of bridge, will pay heavy maintenance cost in bridge construction.
China is in high-grade highway construction, most bridge floors are mated formation and are all failed to take into full account the requirement of bridge functional performance aspect, at present, some bridges that the high-grade highway construction initial stage builds up, its driving functions of mating formation reduces, and because the situation that the seepage of water causes bridge construction to damage is more and more; Some bridges that built up afterwards; though considered the waterproof of deck paving; but the waterproof adhesive property is relatively poor; be difficult to the effect that reaches desirable during construction; and the durability of waterproofing course is relatively poor, simultaneously the protection of bridge construction is paid attention to inadequately, and what have is open to traffic soon that deck paving just begins to occur various diseases; disease repeats again after disposing, and the frequency of maintenance of bridge floor is higher.The neoprene that discloses a kind of usefulness 3～6mm among the Chinese patent CN200420007829.6 is as waterproofing course, and the steel bridge face waterproof paving structure of the thick modified asphalt SMA of the 25～35mm that mats formation; Chinese patent application number is to disclose the employing polyurethane resin in 200410027199 to paste plate object as waterproofing course; A kind of bridge deck water-proof of being made up of poly-imido fat waterproofing materials and bituminous concrete is disclosed among the JP2003160937; Disclose among the JP2002122981 a kind of by the polyurethane waterproofing material, the bridge deck water-proof that thermoplastic bonding material and cast asphalt concrete are formed.Only adopting reaction resin in these inventions is not enough as waterproof, the adhesive property of this one deck and bituminous concrete is relatively poor, deformation performance is relatively poor, and the reaction resin material after the construction is the spreading small crushed stone not, the surface smoother, this will cause pavement layer shear to cut poor-performing, in use occur disease phenomenons such as delamination passing easily.
Three, summary of the invention
Thinking of the present invention is reaction resin bottom impermeable layer, solvent-borne type asphalt rubber and rubber asphalt sand gel to be formed jointly the waterproof system of deck paving.The reaction resin bottom impermeable layer has stronger waterproof sealing process, can guarantee the bonding of interlayer of mating formation for the layer of mating formation provides coarse interface simultaneously, prevents the interlayer passing.The solvent-borne type asphalt rubber has higher adhesive property, can bonding preferably reaction resin bottom impermeable layer and rubber asphalt sand gel, and can not produce simultaneously and pollute environment, and easy construction.Rubber asphalt sand gel has higher water shutoff and deformation performance, can absorb the part distortion of bridge deck, reduces the destruction that produces because of the bridge deck stress raisers, has bonding preferably and cutting performance simultaneously.
