- W3136574494 abstract "This paper raises problem issues of technical conditions of the roads in the Republic in connection with the address of Kassym-Zhomart Tokayev, the President of the country to the people of Kazakhstan.The main problem is poor condition of roads infrastructure resulting in a high level of accidents on dual highways. The second problem is slow rate of roads’ construction and reconstruction according to outdated designing methods and traditional construction technologies for a short operating time of not more than 15-20 years that does not comply with worldwide standards of repair-free service life of roads of 50 years and more. Motorization of the country and freight traffic increases by 25-40% annually, the road load increased 2-3 times resulting in intensive destruction of outdated roads pavements. In connection with this the volume of repairs with respect to costs exceeds more than 50% of total road industry financing. The third problem is a high cost of roads construction. Cost plus technologies are still being widely applied in Kazakhstan. At the same time industrial waste discharge of Kazakhstan’s enterprises accumulated more than 45 billion tons of anthropogenic wastes including petroleum and bitumen containing anthropogenic materials with the application of which innovative resource-saving and power-saving nanotechnologies and nanostructured long-life materials were developed. At the same time, it is possible to reduce the cost of construction and expenses for road maintenance by 2-3 times within 50 years. In addition, to accelerate construction and repairs of 1-2 category roads by 2-3- times, while 3-4 category by 5-6 times. The scientific and technical program headed by national Engineering Academy of the Republic of Kazakhstan for 2021-2023 “To develop and implement efficient technologies of cast-insitu construction of road-transport structures according to world standards with a complex recycling of industrial anthropogenic wastes and recoverable resources” is developed for wide application of nanotechnologies and nanostructured materials in roads construction." @default.
