The technology of laying heavy-duty asphalt has been successfully tested in Russia


In Russia, in the near future, heavy-duty paving may appear, which will finally solve one of the problems voiced by Emperor Nicholas I. Proposed by the ECO Group technology passed successful tests on the experimental section of the federal highway M4 "Don". At the same time, the application of the new development in road construction has already been approved by the Expert Council under the Ministry of Transport of the Russian Federation.


We are talking about adding bitumen modified with TUBALL graphene nanotubes to asphalt concrete. The additive is produced by OCSiAl (part of Rusnano). The latter allows you to create a kind of reinforcing network inside the road surface, which increases such important indicators as compressive strength, fatigue life and rutting resistance.

It is worth noting that the ability of graphene nanotubes to improve the quality performance of asphalt concrete coatings is being studied by specialists around the world. However, only Russian scientists were able to test the technology in practice.

As a result, the tests showed that the resistance of the new asphalt to rutting increased by 67%. The content of “high-tech” bitumen in asphalt does not exceed 6%. In turn, the share of TUBALL in the bitumen itself accounts for only from 0,025% to 0,035%.

The CEO of EKO Group Alexander Greyz emphasized that the next step in the process of introducing new technology across the country will be the design of an appropriate road network.

    About super-duper Russian asphalt, which is about to appear, they write every six months. The last thing I read - with plastic waste - is also super-duper 2-3 times.
    So we are gaining optimism and rereading about Hodja Nasreddin.

    PS And about the cost of Chubais asphalt - silent ....

    Freezing water vomits with terrifying force! And just asphalt holds for years where there is water where to get off the asphalt pavement, not lingering ... We do not live in the tropics!

      Tell it to the Finns, Norwegians and Canadians.

      And the second will remain in the Government.

        Right! Only the second problem is actually the FIRST, so nothing will change!

    Unfortunately, over the past 2 plus centuries, disaster in the letter B has come to the forefront. They began to steal immoderately. It's not about the pavement. About 9 - 10 years ago, the news flashed that some road companies from Germany went to Novosibirsk to learn from the experience of laying roads in Siberia. Then silence. Maybe they adopted it, but here we are - no. The quality of the asphalt is not so important as the compliance of the road design with existing standards, and its laying - with the project. Whatever the asphalt, if it sags or, on the contrary, heats, it will crack and will fall out in pieces. Several years ago, repairs were made in our courtyard. Moscow firm won the tender. And the yard is in Kaluga. Asphalt was transported from Moscow. I'm not kidding. The company has its own factory there. Why should she buy local asphalt when it is necessary to load her plant with work. Concrete curb blocks (lay since 1962 and would lie for another 100 years) were turned out and thrown out. They put new, modern cement. Like paving slabs. The curbs are still holding, the asphalt has peeled off. Already put another.
    So about the roads. In 2005, the head of the Petrozavodsk road company with a simple Russian name Katz laid 9 km of road in the Bezhetsky district of the Tver region. I read the article of the correspondent of KP Vorsobin in 2016.

    https://www.volgograd.kp.ru/daily/26575/3590822/

    At that time, the road stood for more than 11 years and has never been repaired. As of now, I don’t know.

    The mafia will not. There are so many people from the repair of roads fed, mom do not cry!

    will solve one of the problems voiced by Emperor Nicholas I.

    A moot point, just like everything else.
    In Russia it is impossible to create a universal road surface, almost every (many) region (s) has its own climatic nuances.
    Therefore, the regulation on the road surface should be different.
    Plus, the "features" of the operators, which often exceed all possible limits for loading vehicles, and this can kill any road for the season.
