Description
Technical field
The invention belongs to road engineering technical field, be specifically related to a kind of liquid asphalt anti-ultraviolet ageing modifying agent and preparation method thereof.
Background technology
The aging of Colophonium is often divided into the heat ageing caused by high temperature and is irradiated the ultraviolet ageing caused by the ultraviolet comprised in sunlight.In the territory total area of China, the area of more than height above sea level 2000m accounts for 33%, and more than 3000m accounts for 10%, focuses primarily upon western part.These area atmosphere compositions and all different from the plains region, interior ground of low altitude area by way of distance size, its environmental quality is that average temperature of the whole year is low.The main body sunshine-duration is long, and solar radiation gross energy is big, and the ratio of solar spectrum middle-ultraviolet lamp is high, accounts for the 20%～25% of total solar radiation amount, is 4～5 times of hinterland, and strong ultraviolet radiation causes macromolecule material aging phenomenon the most prominent.Relatively fall behind in the strong west area highway line length of ultraviolet, economy, asphalt surface course relatively thin, such as area, Qinghai Province two, Class III highway asphalt surface course only thick 4～5cm, ultraviolet ray ageing will be likely to be breached the 20%～25% of whole asphalt surface course to the impact of asphalt pavement structural layer.The harm after ultraviolet ray ageing of this Colophonium is embodied in: first, the fragility that asphalt surface course produces, and winter low temperature stiffness will be made to be greatly increased, and failure strain diminishes, the as easy as rolling off a log deadly defect becoming warm plastic forming, causes pavement cracking；Secondly, its ductility declines, and easily causes road surface to produce be full of cracks；Finally, Colophonium is deteriorated with the adhesiveness gathered materials, and Colophonium comes off from the surface gathered materials, and produces pit, makes rainwater penetrate into inside pavement structure, causes pavement behavior to deteriorate rapidly, have a strong impact on the serviceability of bituminous paving.At present, existing Colophonium anti-ultraviolet ageing modifying agent is greatly all in the research work stage, major part rests on study mechanism, form the few of product, and mostly use opaque resin, absorbent is added in the middle of Colophonium, although ultraviolet ageing speed can be slowed down, but effect is the most undesirable, and performance of asphalt mixture impact is need demonstration, therefore lay at bituminous paving, maintenance work urgently occurs a kind of ultraviolet that can effectively slow down in sunlight Natural Attenuation to the evaporated residue three norms of emulsified asphalt, Colophonium anti-ultraviolet ageing modifying agent easy to use.
Summary of the invention
The ability that it is an object of the invention to solve the asphalt surface course anti-ultraviolet ageing of existing bituminous paving is weak, and after being irradiated for a long time by the ultraviolet in sunlight, asphalt surface course produces fragility, and winter low temperature stiffness is greatly increased,
Failure strain is little, easily produces warm plastic forming；Ductility declines, and easily causes road surface to produce be full of cracks；Colophonium is deteriorated with the adhesiveness gathered materials, Colophonium easily comes off from the surface gathered materials, produce pit, rainwater is made to penetrate into inside pavement structure, cause the problem that pavement behavior deteriorates rapidly, and provide and can be directly appended in the middle of emulsified asphalt, or be directly sprayed onto on bituminous paving after cooperation solvent, the evaporated residue three norms Natural Attenuation of emulsified asphalt can be slowed down, especially slow down ductility attenuating obvious, a certain degree of can improve the resistance to elevated temperatures of former state Colophonium, improve, improve a kind of liquid asphalt anti-ultraviolet ageing modifying agent of resistance to UV aging of road surface asphalt membrane and preparation method thereof.

Table 1
Interpretation
One, softening point
Softening point is an index of reflection asphalt material heat stability, is also that the one of specific viscosity is measured.Asphalitine and gum level increase can cause softening point to raise.
As can be seen from Table 1: add after the present invention provides the Asphalt Emulsion Evaporation Residue of liquid asphalt anti-ultraviolet ageing modifying agent aging, its asphalt softening point significantly improves than after former state Asphalt Emulsion Evaporation Residue and former state Asphalt Emulsion Evaporation Residue ultraviolet ageing, illustrates that the present invention provides liquid asphalt anti-ultraviolet ageing modifying agent can improve former state Colophonium part high-temperature behavior.
Two, needle penetration
Penetration test is the most commonly used a kind of method measuring asphalt cement denseness, and penetration number is the biggest, represents that Colophonium is the softest.The soft or hard degree of Colophonium is relevant with asphalitine, asphalt content increase, then Colophonium will hardening, penetration index diminishes, softening point improves.
As shown in Table 1: being not added with the Asphalt Emulsion Evaporation Residue of modifying agent after 26d indoor ultraviolet irradiates, needle penetration reduces.It can thus be appreciated that Colophonium asphalt content after ultraviolet irradiates increases.Adding the present invention provides the Asphalt Emulsion Evaporation Residue of liquid asphalt anti-ultraviolet ageing modifying agent after 26d indoor ultraviolet irradiates, its needle penetration also has loss, but loss rate is less than being not added with novel anti-ultraviolet ageing agent, it can thus be appreciated that this interpolation present invention provides the Colophonium of liquid asphalt anti-ultraviolet ageing modifying agent to have the ability of anti-ultraviolet ageing.
Three, ductility
Ductility is the important indicator characterizing Colophonium cryogenic property.Softening point and the cracking resistance of ductility and bituminous paving after the softening point of Colophonium and ductility, especially ageing of asphalt have very close relationship.The ageing resistace being evaluated additive modification asphalt by ductility test is necessary.
As can be seen from Table 1: after the interpolation present invention provides the Asphalt Emulsion Evaporation Residue after liquid asphalt anti-ultraviolet ageing modifying agent aging, its Ductility ratio former state Asphalt Emulsion Evaporation Residue decreases, but than it is significantly improved after former state Asphalt Emulsion Evaporation Residue ultraviolet ageing, it follows that the present invention provides liquid asphalt anti-ultraviolet ageing modifying agent to have the ability of anti-ultraviolet ageing.
