The use of rubble in the old GOST would save almost 1.5 billion rubles for the construction of the federal budget annual expenses. The Accounts Chamber in his report on the analysis of the application of new, economically appropriate, durable materials and technologies in the construction and repair of general use roads in 2018-2020 reports RIA Novosti.
Auditors noticed that at the moment there is no way when building roads is not possible to use asphalt concrete concrete on the old GOST 8267-93. At the same time, the composition of the new mixtures, in particular, asphalt concrete with rubble on a new GOST 32703-2014, not fundamentally changed, but it costs such a coating is much more expensive. Auditors estimated that the inclusion of an old rubble into a list of permitted materials would save 1.4773 billion rubles during the construction of roads every year.
The quality of the road surface would remain at the same level. Thus, indicators of the state of roads built using traditional and new standards are practically no different. And the kachelic of individual sections from new asphalt concrete concrete is the above. In addition, the high porosity of these mixtures can lead to premature destruction of coatings in regions with a wet and cold climate.
Last year, the auditor of the Accounts Chamber Valery Bogomolov explained the poor quality of Russian regional roads. Then during the inspection it turned out that the maintenance of roads in the regions is spent almost eight times less than the content of federal routes. As the mantis stressed, such a situation negatively affects the state of regional roads ..
