Description
Technical field
The present invention relates to a kind of maintenance of surface asphalt material being applied to high ultra-vioket radiation environment and preparation method, specifically relate to
And a kind of uvioresistant rare earth and rubber powder composite modified emulsification asphalt and preparation method thereof, belong to the macromolecule material for road pavement
Material technical field.
Background technology
In recent years, with the fast development of China's transport service, the volume of traffic increasingly increases, and highway construction is also moved with star moon day
Speed develops.Bituminous paving subjects the multiple action of huge traffic load and factor of natural environment, thus to its road material
The quality of material proposes higher and higher requirement.Bituminous paving is in viability because serviceability that is aging and affecting road surface leads to
Its durability is not enough, so that the service life of bituminous paving shortens, this is always the problem of countries in the world concern.
Road asphalt makes Colophonium become not only crisp but also rigid energy bad in viability because the radiation generation of ultraviolet is aging
Change, bituminous paving also occurs the phenomenons such as cracking；Again due to oozing under the impact moisture of rainfall and existing in asphalt surface course so as to send out
Give birth to serious Pavement Performance damage and Moisture Damage and pit etc. occurs, in various climatic environments and increasingly serious traffic loading etc.
Multiple action under, the phenomenon such as pavement cracking, peeling is day by day serious, causes Pavement of Asphalt Road Performance to deteriorate.Therefore, Colophonium is purple
Outer photoaging has become a key factor of impact Pavement of Asphalt Road Performance.
Thus it is necessary to improving Colophonium anti-ultraviolet aging.China's western part road construction problem gradually causes everybody
Concern, in western highlandss, the such as high ultraviolet radioactive such as Tibet, Qinghai area, due to by violent ultraviolet radiation,
Day and night temperature is very big, and bituminous paving is easier the phenomenon of Pavement Performance deterioration to occur, such as in such a case：Cracking, rut become
Shape etc..Therefore, exploitation anti-light aging asphalt material just seems there is very important reality to these height radiation, high temperature difference area
Meaning.Especially high surrounding areas, ultraviolet radiation intensity is higher, causes that bituminous paving is aging to be deepened further, leads to Colophonium
The pavement performance on road surface is deteriorated, and has had a strong impact on the service life of bituminous paving.Numerous studies show, rare earth oxide is to ultraviolet
Line has good Absorption, can effectively reduce the negative effect of ultraviolet after composite glue powder, extends Colophonium and uses the longevity
Life.
