The article analyses applications of waste produced by thermal power plants and used by the road construction industry. One of the promising areas for the use of ash and slag materials is their reinforcement with inorganic binders and using for the construction of pavement. The Russian regulatory documents governing the use of ash and slag materials have several drawbacks, including the lack of recommendations for determining the elastic modulus for bases and coatings made from ash and slag mixtures reinforced with an inorganic binder in laboratory conditions. The lack of these recommendations does not allow the selection of the mixture with specified design values of the elasticity modulus. It makes it difficult to ensure required values of the modulus of elasticity in the construction of road pavement. The authors developed a method for determining the elasticity modulus in laboratory conditions in order to produce materials with specified values of the elasticity modulus and improve quality of design and construction of road pavement from ash and slag mixtures reinforced with inorganic binders.
