摘要
The relevance of the study is due to the modern production being focused on the development of efficient materials that would provide for the minimum consumption of raw materials, a decrease in its cost and energy during the production and direct use of secondary resources. That is because recycling, disposal, neutralization and collection of industrial waste are one of the most pressing environmental problems. The aim of this work is to consider the feasibility of using fiber from fly ash from thermal power plants in China in the main types of asphalt concrete pavements. The results of the research have shown that the fiber from fly ash from thermal power plants is added to all purpose concrete mixtures for structural strength, impact toughness, reducing shrinkage and to prevent cracking, increase durability and resistance to abrasion. Concrete with the addition of fiber becomes water-resistant, frost-resistant (frost-resistance can increase up to 100 cycles), heat-resistant. The practical task is to solve environmental problems, such as assaving significant amounts of fuel in the production of building materials and energy; and conserving natural resources.
