ABSTRACT

The technical efficiency of using the encapsulated modifier for self-healing of asphalt concrete consists of both a set of indicators of the quality of asphalt concrete, ensuring its functioning in the structure, and the ability to resist operational factors and preserve the original properties. The economic efficiency of using the encapsulated modifier for self-healing of asphalt concrete is ensured by reducing the costs of producing a unit of product with increased quality indicators, as well as reducing the costs of repair and maintenance of roads due to an increase in the period of repair-free operation. The pa-per assesses the technical and economic efficiency of using the encapsulated modifier for self-healing of asphalt concrete by changing the quality of the material δQs, which is achieved per unit of product taking into account the change in its cost δC due to the use of additional components. The quality of asphalt concrete is determined by a set of properties that are characterized by the corresponding indicators of physical, mechanical, operational properties and self-healing properties. The quality of the material Qs at any time from the beginning of operation can be assessed using a multiplicative-additive function. The use of an encapsulated modifier with an AR-polymer as a reducing agent and activator in the amount of 3% and 3.5% of the bitumen mass, respectively, contributes to an increase in the cost of one ton of crushed stone mastic mixture by 20%. The quality of asphalt concrete with an encapsulated AR-polymer increases by 30% with equal weight coefficients. The technical and economic efficiency of asphalt concrete with an encapsulated AR-polymer is 54% higher than that of traditional SMA-15.
