Abstract
The invention relates to a preparation method for an asphalt mixture for road paving. The asphalt mixture comprises the following ingredients in parts by weight: 100 parts of asphalt, 20-30 parts of crumb rubber, 0.5-2.5 parts of a surface active agent, 10-15 parts of one or two of paraffin and/or rosin, 20-35 parts of resin and 5-10 parts of padding. The improved asphalt mixture can effectively improve the performance of asphalt, and is suitable for paving road surfaces, long in service life, simple in preparation technology, easy to operate and low in cost, and the follow-up maintenance cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of preparation method of the asphalt mixture for road pavement.
Background technology
Pitch is the viscous liquid or solid that are substantially made up of hydrocarbons and their derivates.It dissolve in trieline neutralize when heated assembly soften.By pitch and aggregate and filler combination to form asphalt, subsequently asphalt is used for laying road or other surface.
In the paving of motorway or parking lot, goods yard, walkway etc., owing to laying than being easier to, and time from paving operation to communications and transportation starts is short, so the pitch mostly having carried out use asphalt mixture is paved.Such as, in the motorway of current Japan, 95% of total floor slab is paved for pitch.This pitch is paved and is formed road surface by utilizing pitch to combine the asphalt mixture gathered materials, and has good hardness and weather resistance.
But pitch is owing to being manufactured by the refining of oil, so have the character in the gasoline, light oil, heavy oil, kerosene, cylinder oil etc. being dissolved in and being similarly petroleum spirit goods.Therefore, when making on these oil leakages to road surface from reasons such as leakages vehicle etc. because of fuel or lubricating oil, early stage pitch dissolves, infringement asphalt mixture, causes hollow etc. to pave destruction.Therefore, result is the repairing must carrying out paving, and maintenance cost increases, and makes a big impact to the traffic of automobile.As the method using the fast asphalt series mixture of speed of application, can consider to utilize and compare paving of the half flexible hybrid thing with oil-proofness.This is filling concrete serum the method making it solidify in the space of the asphalt mixture of open gradation.Use half flexible hybrid thing pave be by the solidification of cement, rut is formed resistivity is comparatively strong, the paving of excellent in te pins of durability.But, although half flexible hybrid thing demonstrates oil-proofness compared with common asphalt mixture, but after parent open gradation asphalt mixture is constructed, need in the space of asphalt mixture, inject the such operation of cement emulsion slurry, what so existence is constructed, the engineering time that is numerous and diverse, needs more than 2 times compared with common asphalt mixture was such paves same shortcoming with cement concrete.
In addition, as the method for other use asphalt series mixture, the bituminous epoxy mixture using and compare the epoxy resin with oil-proofness is had.This is the mixture being replaced as epoxy resin by about 15 ~ 30% of pitch and obtaining.Here used epoxy resin is the reaction resin be made up of two components of host and solidifying agent.Because epoxy resin cured product is insoluble to oil, thus be compare there is oil-proofness and by the solidification of epoxy resin, rut is formed resistivity is comparatively strong, the paving of excellent in te pins of durability.In addition, as another other countermeasure, can consider to utilize by coordinating in pitch with SBS (styrene-butadiene-styrene block copolymer) etc. for the thermoplastic elastomer of representative and the modifying asphalt that obtains.In fact, modifying asphalt have improve the rut that pitch is paved formed and crack resistivity effect, in recent years, there is the achievement of a lot of reality utilized.According to above situation, need to lay than after the advantage such as being easier to, speed of application is fast, the time from paving operation to communications and transportation starts is short effectively utilizing, oil-proofness excellence, the asphalt mixture paved that weather resistance is high can be realized.
Summary of the invention
The invention provides a kind of preparation method of the asphalt mixture for road pavement, comprise following component: pitch 100 weight part; Crumb rubber 20-30 weight part; Tensio-active agent 0.5-2.5 weight part; One or both 10-15 weight parts in paraffin and rosin; Resin 20-35 weight part, filler 5-10 weight part.
Add and first paraffin is heated to molten state together with one or both in rosin add in pitch man-hour, then other component is joined in pitch and stir.
The tensio-active agent used in the present invention is cats product, is one or both in Trimethyllaurylammonium bromide, cetyl trimethylammonium bromide; Resin is the one in epoxy resin, polyamide resin, preferred epoxy; The filler used is carbon black, one in calcium carbonate, preferred carbon black.
The invention has the beneficial effects as follows: pitch prepared by the present invention, effectively can improve the performance of pitch, be applicable to laying road road surface, long service life, decreases follow-up maintenance cost; A large amount of old and useless articles can be adopted, both reduced production cost, also reduce environmental pollution; Waterproof, good freezing protection effect; After adding rosin or paraffin, melting point reduces greatly, greatly reduces energy waste; Production technique of the present invention is simple, and easy handling, with low cost, raw material is easy to get, and the cycle is short.
