Description
Technical field
The invention belongs to asphalt road surface preventive maintenance field, be specifically related to a kind of novel quick-dry type drop regenerator.
Background technology
Traditional Asphalt Pavement Maintenance Technology carries out repairing or keeping in repair often after disease appears in road again, this maintenance method usually because pavement disease is fragmentary, line length, wide and comparatively dispersion cause that construction is loaded down with trivial details, work efficiency is low, cost is high.And drop regeneration preventive maintenance is as a kind of brand-new Asphalt Pavement Maintenance Technology, propose the concept of preventive maintenance, namely maintenance work just carries out maintenance in bituminous pavement " greatly " problem when even " little " problem also not yet occurs, thus reduce the work-ing life that breaking of pitch surface in early stage extends bituminous pavement.
Have longer history to the investigation and application of drop regeneration preventive maintenance abroad, this preventive maintenance promotes the use on state's motorways such as the U.S., Canada, Brazil, and achieves tremendous economic and social benefit.With regard to the applied research level of current China drop regeneration preventive maintenance, be also in the stage of fumbling on the whole, not yet form complete construction technology and quality control standard.
The patented product drop regeneration (RejuvalSeal of the U.S.
tM), bituminous pavement can be infiltrated rapidly and moltenly with it to be integrated, supplement or increase oily matter needed for pitch, recovering aged asphalt active, thus increasing the snappiness of bituminous pavement, elasticity and cohesive force.But its price is relatively high, because the difference of weather and environment, also there is certain difference in the regenerability on " drop regeneration " road surface, therefore the domestic similar substitute products of development are badly in need of, develop the drop regenerator that can be suitable for domestic climate characteristic, pavement structure, reduce the maintenance cost on " drop regeneration " road surface, be conducive to this novel maintenance technology promoting the use at home.
Summary of the invention
The object of this invention is to provide a kind of bituminous pavement quick-dry type drop regenerator and preparation method, product can powerfully infiltrate in bituminous pavement, supplements or increases oily matter needed for pitch, recovers aged asphalt activity and makes road surface recover using function; Can form layer protective layer on bituminous pavement surface, anti-sealing, gasoline and chemical etc. invade bituminous pavement simultaneously; Have price more cheap, shaping fast, affect the features such as open to traffic lacks.
Realizing the technical scheme that above-mentioned purpose of the present invention takes is: the weight percent of each component is, the tackifier of 20 ~ 25%, the petroleum pitch of 4 ~ 8.5%, 0.9 ~ 2% siccative, all the other are tenderizer, wherein tenderizer is 280 ~ 360 DEG C of aromatic hydrocarbon oil cuts that distillation tar intercepts, tackifier are carbon 9 petroleum resin, the one of carbon 5 petroleum resin particle or two kinds, petroleum pitch is 70# matrix pitch, the one of 90# matrix pitch or two kinds, siccative be aluminum oxide, dimethylbenzene any one.
The concrete weight percent of the described each component of drop regenerator is: the tenderizer of 70%, the tackifier of 23%, the petroleum pitch of 5% and the siccative of 2%, and product is liquid form mixt.
The concrete preparation method of drop regenerator of the present invention is: good for proportioning tenderizer, tackifier, petroleum pitch and siccative are added successively in reactor, at 50 DEG C ~ 160 DEG C, stirring velocity controls at 60 ~ 80 revs/min, mix and blend 0.5 ~ 1 hour, be cooled to normal temperature, obtain drop regenerator product.
Using method of the present invention is:
1, consumption of constructing is determined: former road surface is chosen A, B, C totally 3 test points, brush respectively on the different bituminous pavement of size with the drop regenerator of same amount, after 24 hours drop regenerators are completely dry, test the depth of penetration of each test block, be most suitable construction consumption with depth of penetration at the drop regenerant consumption of more than 1cm.
2, the dust of road surface and other foreign material must be cleaned clean in first 2 days in construction, and be dried up.
3, crack place forced air compressor connects gas larynx and nozzle, and the sandstone in crack and refuse cleaning is clean, fills up agent or base joint grouting glue will comparatively be filled and led up by large fracture with crack.
4, thoroughly drop regenerator is stirred, till without any precipitation.The drop regenerant consumption determined by test in place before construction is opened and is spilt oily car valve, sprays drop regenerator accurately, uniformly.
5, after drop regenerator is completely dry, open to traffic is got final product.
Advantage of the present invention is:
1, use in early days at bituminous pavement, by external coating drop regeneration techniques, make its elasticity recovering new road surface and snappiness, make road surface be in best using state for a long time, and the cost of product is lower.
2, the present invention is that one has infiltrative asphalt-regenerating sealing agent, can form layer protective layer on bituminous pavement surface.
3, bituminous pavement can be infiltrated rapidly and moltenly with it to be integrated, supplement or increase oily matter needed for pitch, recovering aged asphalt active, thus increasing the snappiness of bituminous pavement, elasticity and cohesive force.
4, external coating drop regeneration preventive maintenance constructing operation is simple, does not need to heat starting material, mix during construction, decreases the pollution to surrounding environment.
When 5, using of the present invention, the construction close traffic time is shorter, gets final product open to traffic in 4 hours.
