Production of asphalt concrete coatings with improved performance properties

Head: Dyuryagina A.N., Candidate of Chemical Sciences

Semi-industrial tests of the adhesion additive of thermal sealant (GT, thermal modification of the sealing fluid AG-4I) as part of the asphalt mix for coating the road to SU-808 LLP (Petropavlovsk) are carried out.

Scientific novelty lies in the development and implementation of technology for the production of hardened asphalt concrete pavements based on the rational utilization of waste and waste materials from enterprises in the region. A dramatic and at the same time minimal cost improvement in the quality of asphalt concrete pavements when modifying their composition with the recommended polymer additive GT is provided both by adhesive, hardening, and waterproofing effects.

This project will make it possible to exclude the use of expensive, currently purchased at a cost of over 600 thousand tenge per 1 ton of imported adhesive additives and to ensure at the stage of production of asphalt concrete a cost reduction of not less than 12 million tenge with a production volume of 20,000 tons of asphalt concrete per year 600 tenge per ton. In addition, the project will make it possible to rationally utilize the accumulated waste of the regional enterprise Petropavlovsk Heating Networks LLP, improve the environment and solve the problem of paying penalties (over 800 thousand tenge per year).

The economic effect of the implementation of the proposed technology on the production volume of 100 tons of asphalt concrete mix will be 26 743 tenge (excluding VAT) or 267.43 tenge per ton.
