Description
Technical field
The invention belongs to Communication and Transportation Engineering construction field, relate to the improvement of a kind of road construction material.
Background technology
The asphalt material of a large amount of high-quality is needed in the fast development of highway badly, traditional Colophonium mostly be imported crude oil refining and
Become, relatively costly.Current China highway mileage rapidly increases, and by the end of the end of the year 2015, highway mileage has broken through 12
Ten thousand kilometers.Statistics shows, building every kilometer of highway needs Colophonium more than 400 ton, the huge market demand to promote asphalt price
Quick rise, 2011, China's asphalt price reached 5200 yuan/ton.And Bureau of Customs of U.S. numeral shows, from 2003 years
Between 5 years risen, asphalt price increases by 25% every year, 300% peaked for 2008.Although international crude petroleum is due to the world in the recent period
Situation upheaval and prices, but day by day exhausted along with petroleum resources, the Faced In Sustainable Development of road construction huge
Challenge.Therefore, research and develop novel asphalt material to carry out petroleum replacing Colophonium and have become as the heat of domestic and international pavement engineering area research
Point.
After Biological asphalt refers to produce plant amylum, dihydroxylic alcohols, the oils and fats such as gained side-product waste material and production fatty acid produces
The Colophonium class material that industry downstream side-product etc. are prepared through liquefaction, distillation and separating-purifying, it has wide material sources, low cost
Honest and clean, green non-pollution and reproducible feature.
Crude oil non-renewable causes the continuous atrophy of Colophonium resource, finds in the weight that substitute products are road fields it
Weight.At present, the highway of China more than 90% is bituminous paving, and the maintenance and reconstruction of existing cement concrete pavement also more to be used
" paracetamol " form, it is anticipated that the following demand to Colophonium is growing on and on.Up to now, the Colophonium used in road construction
Mostly come from Fossil fuel, especially crude oil.And crude oil is as non-renewable energy resources, its reserves reduce day by day, search for oil
The substitution material of Colophonium is imperative.One of selection is to use cement concrete pavement instead, but cement pavement not only expends the most not
Reproducible building stones, comfortableness is poor simultaneously, maintenance difficult.Therefore, new replacing asphalt product is developed particularly important.
Biomass obtain bio oil after extracting industrial products, and improvement upgrading further to bio oil is just made may replacement
The Biological asphalt of conventional petroleum Colophonium.Biological asphalt has reproducible concept and environmentally friendly feature.By Biological asphalt
Industry byproduct can be alleviated and offal treatment causes ambient pressure for road engineering, and because Biological asphalt only needs
Machining at low temperature, its energy consumption is lower.On the other hand, Biological asphalt wide material sources, cost is relatively low, and application can produce relatively in the road
Big economic well-being of workers and staff.
Summary of the invention
It is an object of the invention to: provide a kind of road biological rubber modified pitch and preparation method, it utilizes biology drip
Blue or green Substitute For Partial asphalt, and fill rubber powder and styrene butadiene styrene block copolymer (SBS) is modified, it should
With not saving Renewable resource, and improve the performance of asphalt.
