Kazakhstan Develops Technology to “Revive” Worn Asphalt
Scientists at the Kazakh Road Research Institute (KazdorNII) are developing a technology that restores worn asphalt for reuse in highway repair and construction. According to the institute, the project involves the creation of an innovative restorative compound. Experts say that the regeneration process could significantly reduce construction waste, lower energy consumption, and cut CO₂ emissions during asphalt production. This model supports more sustainable road construction by giving materials a “second life.” “We are developing solutions that allow existing resources to be restored instead of consuming new ones. This will not only reduce the burden on the environment but also make the road industry more efficient and technologically advanced,” said Saltanat Ashimova, head of the department of road construction materials and new technologies at the institute. The initiative is part of a grant awarded through a competition for scientific and technical projects for 2025-2027. The research is focused on integrating green technologies into road construction. The institute expects the new compound to be environmentally friendly, produced domestically, and adapted to Kazakhstan’s climate and road conditions. Its use is expected to improve road surface durability and quality, while supporting the country’s shift toward a sustainable economy. As previously reported by The Times of Central Asia, severe road surface deformations were recorded across inter-city highways in Kazakhstan this summer amid extreme heat.
