Scientists have created the University of Irkutsk asphalt-based

nanomodifikatorov

Small innovative enterprise CJSC "Nanotehtsentr", established on the basis of Technopark Irkutsk State Technical College, University of, — One of the winners of projects for the Valley innovation. Organizer of the contest, aimed at creating the conditions for the commercialization of innovative technologies in the field of urban beautification, acts of administration of Irkutsk. Innovators IrGTU propose to use in the Angara asphalt with mineral supplement based on polymers and nanomodifikatorov own design. According to the authors of the project, the product may be a good alternative to expensive polymer modified binder. It is planned that by October this year in Irkutsk on a section of road will be coating technology developed by scientists.

General Director of "Nanotehtsentr" Peter Nelyubin said that the issue with the choice of the experimental site is being coordinated with the city administration and MUP "Irkutskavtodor". Subsidies designed to perform, is 1.1 million. With funding for the project is based on a public-private partnership: 40% paid by employer, 60% — the administration of the city. As noted by one of the authors of the project, Associate Professor of roads IrGTU Victor Alekseyenko, mineral supplement significantly improves the performance of asphalt concrete, including durability and frost resistance. Asfaltvyazhuschego softening temperature is 60 °, frost reaches minus 32 ° (y conventional bitumen, these figures at 35 ° and -25 °).

Thus, asphalt, produced by scientists IrGTU technology, will serve on the road for three times longer. "Poor determined low quality asphalt bitumen which is generally not consistent with our climatic conditions. Russian scientists have long been working on technologies to improve bitumen. For example, polymers are added to the bitumen — synthetic rubber. However, this is a complex and expensive process, — said Victor Alekseyenko.

— We have developed a method in which a polymer is added to the bitumen is not, as one of the essential elements of asphalt — mineral powder (dolomite powder). For this we use the composition of special additives and carbon nanoparticles. These molecular formations possess unique properties that effectively reacts with the surface of polymers and inorganic fillers. The modified nanoparticles are formed by mechanochemical treatment of dolomite, polymer and carbon nanoparticles. As nanoparticles dry product we used the silicon removal plant. " An additional benefit of this technology is unlimited shelf life of nano-modified dolomite.

If the production of polymer modified asphalt binders each bitumen plant, significant additional investment, the scientists IrGTU method can be applied to existing plants without changing the process. At the same appreciation of the asphalt will not exceed 10%.

The administration of Irkutsk is implementing the project "Innovation Alley" for the third year. Within two years, on an experimental platform for practical testing of innovative companies offering new technologies in the field of housing and urban development, implemented nine projects worth $ 2.3 million.

These projects are the installation of energy-saving street lamps, colored caps on poles, vandal-proof benches, interactive stops, solid borders, the use of crumb rubber from used tires, etc. All the innovations will be tested in real-world weather conditions and in active operation. Among the projects Irkutsk Technical University, located on the Avenue of innovation interactive advertising stand with elements of "machine vision", vandal-proof benches of innovative building material "VINIZOL" vetrosolnechnaya installation.
