Description
Technical field:
The present invention relates to a kind of modifying asphalt and its production and application, especially a kind of high performance pavement material of epoxy asphalt of laying road and bridge and its production and application that is used to.
Background technology:
Pitch has excellent waterproof property and adhesive property, and aboundresources, and is cheap, therefore is widely used in ground surface material, water-proof material and sealing material for a long time.But because the lower and molecular weight distribution broad of bituminous relative molecular mass, its mechanical property is big to temperature sensitivity, and low temperature easily becomes fragile, and high temperature easily trickles, and does not almost have elasticity, and ageing resistance is poor again, so limited the bituminous widespread use greatly.
Along with China's modernization construction speed is advanced by leaps and bounds, the high speed development of communication, a large amount of makings of high-grade highway, it is important and general that the use of road bitumen more and more seems, improves road bitumen work-ing life, increases the road comfort, improves the passenger and freight throughput rate, reduces the problem that tire chafing etc. is eager to solve and put in face of R﹠D institution and unit in charge of construction.While is owing to highway bridge building in a large number, it is more and more outstanding that the deck paving problem also seems, especially bridge floor is easy to produce early damage, bridge generally all is the bottle neck area of traffic, the volume of traffic is concentrated, bridge floor is subjected to temperature variation also bigger, and automobile load effect causing bridge deformation and vibrations all have tangible influence to the layer of mating formation.Paving steel bridge deck particularly, the bridge floor deflection is big, needs asphalt that stronger deformability is arranged during winter low temperature, during summer high temperature, the used pitch of steel bridge deck paving not only needs good rutting resistance, low temperature cracking resistance ability, and also the resistance to deformation fatigue capability also should be good.Therefore, have only, could satisfy above-mentioned the high performance requirement of pitch to the plain asphalt modification.
In order to improve the bituminous performance, can change the characteristic of traditional asphalt with macromolecular materials such as rubber, elastomerics, plastics.Come modifying asphalt as add macromolecular materials such as SBS, APP, EVA, SBR in pitch, the bituminous physicals has obtained very big improvement.But this method of modifying be based on macromolecular material with pitch blend process in form the cross-linked network of physics, the physicals of modifying asphalt improves limited, though it is this modifying asphalt can satisfy the requirement of prevailing roadway, still very undesirable to the wide road surface of high loading heavy traffic road surface and range of temperature such as bridge road surface etc.
Summary of the invention:
The objective of the invention is to:, provide a kind of new component and preparation method and concrete the application asphalt modification at the above-mentioned problem that generally adopts physical crosslinking to exist to asphalt modification.
The object of the present invention is achieved like this: a kind of high performance pavement material of epoxy asphalt, comprise A and B two portions, and it is characterized in that;
The A part is made up of following materials in parts by mass:

B part: Resins, epoxy;
The A part is 2.5～7: 1 with the mass ratio of B part.
In part: described solidifying agent is a modification binary long-chain fat carboxylic acid; Described promotor is aromatic amine or highly basic; Described defoamer is a low molecular polyether.Wherein: described modification binary long-chain fat carboxylic acid is: modified tung oil acid, modified castor oil acid; Described aromatic amine is a benzylamine, and described highly basic is KOH; Described low molecular polyether is the multipolymer of oxyethane and propylene oxide.In the B part: described Resins, epoxy is low-molecular-weight bisphenol A type epoxy resin.
During enforcement, solidifying agent is selected 1～2 kind of modification binary long-chain fat carboxylic acid.
The preparation method of above-mentioned high performance pavement material of epoxy asphalt, comprise the following steps: a) pitch to be heated to 100～120 ℃, with solidifying agent join in the pitch stir mixed after, transfer to and carry out high speed shear in the colloidal mill and be uniformly dispersed, the shear-mixed time is 10～60 minutes, add promotor, defoamer again and carry out high speed shear and mixed 5～50 minutes, obtain the A part; B) use before, the A that obtains partly is heated to 100～160 ℃, again with A part and B partly in 2.5～7: 1 ratio is 120～140 ℃ of following mixing and stirring, and keeps 4～8 hours, solidifies back acquisition epoxy asphalt road surface materials.
The concrete application of above-mentioned high performance pavement material of epoxy asphalt partly is heated to 100～160 ℃ with the A that obtains before using, and the A part is mixed under 120～140 ℃ in proportion with the B part, as the main raw of producing epoxy asphalt concrete again.
When the part of the A in the above-mentioned high performance pavement material of epoxy asphalt partly being mixed in proportion with B and stirring under 120～140 ℃, add an amount of building stones and auxiliary material in the stirring simultaneously, placed 30～60 minutes the back that stirs, and obtains the epoxy drop
Blue or green concrete directly is layed in the road surface, solidifies the formation epoxy asphalt road surface through 4～8 hours.
The invention has the advantages that: owing in to asphalt modification, adopt modification binary long-chain fat carboxylic acid as solidifying agent, and form the characteristics of cubic network structure by Resins, epoxy generation chemical crosslink reaction, improve the fatigue performance under pitch weathering resistance and the high temperature working conditions.Utilize Resins, epoxy and other material superior bond strengths rendering simultaneously, improve bituminous concrete medium pitch and the bonding strength of building stones and the cohesive strength of pitch and coated material, thereby prepared a kind of high performance epoxy asphalt road surface novel material.It has good solidity to corrosion, water tolerance, oil-proofness, weathering resistance, resistance to fatigue, high temperature creep resistant and low temperature resistance to brittle fracture.Can be used as uses such as making bituminous concrete, cushioning material, water-proof and anti-corrosive material.
