Description
Technical field
The invention belongs to waterproof construction technology fields, and in particular to a kind of pavement construction method.
Background technique
At freeway toll station, automobile causes gasoline imperfect combustion to discharge a large amount of CO and NOX using idling traveling
Equal toxic gases, have serious harm to the health of staff；At the same time, due to the influence of canalized traffic, heavy duty
Vehicle easily causes the track on road surface to damage when low speed passes through charge station, and especially in the summer high temperature time, track damage can more
Add serious.
Summary of the invention
For above-mentioned the technical problems existing in the prior art, present invention technical solution used for the above purpose
It is:
A kind of pavement construction method, specific step is as follows for construction: (1) when concrete just solidifies, carrying out to concrete
The processing of plucking；Because just will appear many laitances thereon when solidification, if not removing, roadbed surface layer can be made crude, and by
It will combine more closely, have more after mechanical equipment removes it, between waterproof layer, concrete road surface and bituminous concrete
High degree of adhesion.There is also some points for attention, including concern waterproof material type, different materials to have difference in operation
Basal plane depth, the requirement of crude degree, also just changed correspondingly with degree the case where hair pulling treatment.
(2) smooth-riding surface checks that roadbed is uneven, ponding, the phenomenon that falling off, and sweeps the rubbish of road bed and miscellaneous
Object is finally blown clean basal plane with dust blower；Waterproof layer has stringent want when being constructed, to the flatness of roadbed
It asks.How to guarantee the smooth of roadbed, is the key that guarantee quality of waterproof layer.Therefore to check roadbed either with or without rough existing
As, either with or without ponding, fall off the phenomenon that etc..There is no part up to standard to flatness, conscientiously reprocess.Guarantee roadbed
It is smooth.This requires staff to keep the clean of road bed, and in time by the rubbish of road bed, spot is swept.Finally
Basal plane is blown clean with dust blower.
(3) activator solution is sprayed to road bed；Activator solution will have when roadbed waterproof layer first layer sprays
Good addition effect, after being made an addition to earth material surface and suitably being diluted, earth material gap is changed, bigger gap
So that the involvement situation of water-proof liquid rubber spray paint is more preferably, bondability further gets a promotion, and can more play the effect of waterproof
Fruit.
(4) roadside anti-collision wall is blocked with cloth；When bridge floor carries out water-repellent paint injection, it should be noted that anti-collision wall is blocked with cloth,
The waterproof layer of its bottom is manually brushed, and coating can effectively be avoided to pollute anti-collision wall in this way.
(5) it sprays waterproof layer: spraying waterproof layer using liquid rubber spray-coating material, the twice coating spraying material direction of contact is answered
Orthogonal, liquid rubber spray-coating material sprays three times；It is noted that liquid rubber spray-coating material sprays three times, when spraying in operation
It need to ensure that last spraying parches completely, its effect is made to be not fully exerted.
(6) protecting field basal plane, waterproof layer thoroughly air-dry asphalt concrete layer of mating formation later, and bituminous concrete mixes 1% dioxy
Change titanium powder；Be painted with after waterproof layer, waterproof basal plane just basic construction finishes.When road formally comes into operation,
With before asphalt concrete layer of mating formation, or it is noted that protecting field basal plane.After waiting waterproof layers thoroughly to air-dry, it could put into
It uses.And within 10 t of weight that should be ensured that vehicle driving on the road.Meanwhile it is anxious above to reduce vehicle
Brake.
(7) spraying liquid rubber spray paint again.
Further, the specific ingredient of the liquid rubber spray-coating material are as follows: the liquid rubber spray-coating material is divided into two kinds of A, B
Component；The A group is divided into anion liquid body rubber asphalt emulsion；The B group is divided into coagulant solution；The component A, with matter
Measuring percentage indicates, liquid rubber asphalt emulsion weight solid content is 50-75%, wherein rubber latex 10-25%, pitch cream
Liquid 1-60%, anionic dispersing agents 0.01-2%, anionic surfactant 0.01-2%, fatty alcohol polyoxyethylene ether 0.1-
10%, OEP-70 0.1-10%, AEP 0.1-10%, carbon black 0-3%, fine powder material 0-3%, nano titanium dioxide powder 0.5-
20%；The B component, is indicated with mass percent, is 3-by the concentration that calcium chloride, Complex aluminium-iron mixed with polymers are formulated
18% aqueous solution, the Complex aluminium-iron polymer are one or both of aluminium polychloride, bodied ferric sulfate；It is described to have
The spraying capacity ratio of liquid rubber spray-coating material B component and component A is 1/15-1/3.5.
Compared with prior art, the beneficial effects of the present invention are: the present invention provides the liquid containing nano titanium dioxide powder
Body rubber spray paint has good mechanical property and anti ageing property.When being sprayed on the road surface outermost layer for being exposed to and being directly exposed to the sun
When, the titanium dioxide in formula can shield or sponge the ultraviolet light in sunlight, and capture tail gas using ultraviolet light, be aoxidized
It decomposes, promotes the photostability for strengthening rubber spray paint, not only there is good tail gas degradation efficiency, recyclable efficiency and heat
Reflection performance also extends the service life of highway pavement with good road with endurance quality.
