Description
Technical field
The present invention relates to a kind of asphalt pavement pit repair materials and preparation method thereof, belong to highway material and applied technical field, relate in particular to organic/inorganic composite material of a kind of quick reparation asphalt pavement pit and preparation method thereof.
Technical background
Asphaltic road-mix surface course has the features such as construction speed is fast, maintenance simple, it is comfortable to drive a vehicle, surfacing, widely applies in China.But after bituminous pavement experience certain hour, due to high loading driving for a long time, extreme climate environment, temperature variation, rain erosion etc., all can damage bituminous pavement in various degree, cause cohesive force between pitch and base-material to reduce, under automotive wheel dynamic load repeated action, pitch comes off from base-material surface, pavement destruction is damaged to profound structure deteriorate development from shallow table gradually, destroys development from the local damage of small area to large-area monoblock.In order to ensure quick, safe, comfortable, the efficient Characteristics of Transportation of motorway, extend the work-ing life of motorway, make the economic and social benefit that its performance is larger, thereby need road pavement to carry out the maintenance and repair of normalization, the generation of the normal operation of guaranteeing highway to try to forestall traffic accidents.
Traditional repair materials is mainly hot-mix asphalt mixture, but this repair materials exists the defect that pollution is high, cost is large, and in addition, the impact of hot-mix asphalt mixture climate condition is larger,, should not construct because temperature is compared with low unsuitable compacting in cold season.Using in recent years more is asphalt cold repairing repair materials, as Emulsified Asphalt Mixture.Asphalt cold repairing repair materials has overcome the defect that hot-mix asphalt mixture low temperature should not be constructed, but in the time using cold repairing asphalt mixture redeck, after needing equal solvent to evaporate completely, just can play the effect of enhancing, so cold repairing asphalt mixture exist initial strength low, strengthen shortcoming slowly, can not reach the object that quick reparation is open to traffic fast, larger to traffic impact.Therefore novel material, new approaches, the novel process that proposes a kind of quick reparation asphalt pavement pit is very meaningful and is necessary.
Publication number is that CN101993222A discloses " a kind of pitch that is exclusively used in redeck and preparation method thereof ", mainly, taking plain asphalt, styrene-butadiene rubber(SBR), wilkinite, vibrin, gasoline, kerosene, talcum powder as raw material, prepare and be exclusively used in the pitch that redeck is used.This pitch is applicable to redeck and uses, can with the good combination of former pavement asphalt, extended work-ing life of highway.
Publication number is that CN102701787A discloses " a kind of bituminous pavement anti-freezing ice injury repairing material and preparation method thereof ", can solve existing maintenance and cannot resist the destruction problem that multigelation produces, its repair materials is made up of road oil hard pitch, coal-tar heavy oil and viscosity reduction permeate agent.
Publication number is that CN1970491A discloses " a kind of cement for quick reparing sill of Asphalt Pavement Semi-rigid Base ", its component is quick-setting and rapid-hardening cement, sand, stone, water reducer, fiber, specialist additive, water etc., can make foreshorten to 4 ~ 8h the repair time of bituminous pavement, alleviate to a certain extent road surface and repaired the impact on traffic congestion.
In addition, Zhang Wenjing, Wang Hui etc. are at " express highway pavement is repaired the research with polyurethane concrete fast " concrete, 2011(5), taking hard polyurethane foam as base mateiral, prepare polyurethane concrete material in conjunction with normal concrete technique, can realize the quick reparation of expressway surface in 2h.
Li Li, Wang Hongbin etc. " the synthetic and performance study of urethane/silicon carbide matrix material " New Chemical Materials, 2014, in 42 (3), with toluene diisocynate and the synthetic performed polymer of diphenylmethanediisocyanate, taking E300 as chainextender synthesis of polyurethane elastomerics, repair as base material road pavement hole groove, can realize the quick reparation of bituminous pavement in 2h.
Although above-mentioned disclosed method, has accelerated the reparation of bituminous pavement to a certain extent, also has some problems, the one, contain organic solvent as gasoline, kerosene, coal tar wet goods, environment is had to pollution, affect operative employee's physical and mental health; The 2nd, the repair materials construction speed taking cement as main base material is slow, and setting rate is slow, and the road closure time is long; The 3rd, after repair materials sclerosis, does not mate with the rigidity of bituminous pavement, split away off from road surface after rolling through vehicle after a while.
Summary of the invention
The present invention is directed to asphalt pavement pit and repair problem, a kind of organic/inorganic composite material of quick reparation bituminous pavement is provided, this type material at normal temperatures just can fast setting, not only bituminous pavement is had to very strong cohesiveness, and do not contain low volatilization and poisonous organic solvent, be a kind of Cost of New Type Asphalt Pavement hole groove material for quickly repairing of environment-friendly type.This type material mixes after cast liquid mixture can flowing time≤10min, ambient cure time≤30min, and 90min has enough loading strengths to be open to traffic, and can guarantee the driving safety of vehicle, reaches the object of quick reparation.The present invention has not only solved the problems such as process complexity problem, curing speed that prior art repairs asphalt pavement pit be slow, and material after repairing has the performances such as good resistance to compression, anti-shearing, water erosion resistent, heat resistanceheat resistant be cold.
