Kazakh scientists have introduced water-repellent asphalt that has no analogues not only in Kazakhstan but in the world. Thanks to the use of a special mixture, the lifespan of highways is expected to increase to 10-15 years. The development has been tested on the country’s roads since this spring. Another innovation by local scientists is a modifier designed to eliminate rutting.
«All our developments are based on materials used here in Kazakhstan - our gravel, bitumen, climate, working conditions, and mentality. Everything has been designed exclusively for local conditions: for Northern Kazakhstan, for Southern Kazakhstan with its high summer temperatures, and for Western Kazakhstan, considering the effects of saline water and winds,» said company’s developer-technologist Azamat Umarov.
Kazakhstan has also launched a unified database of road construction materials and new technologies. It contains around 300 developments, 50 of which have already been tested and proven effective on highways. These include not only next-generation asphalt concrete mixtures but also soil stabilizers. They not only increase the durability and strength of road surfaces but also speed up construction and reduce costs.
«Most of the
materials listed with a green status - that is, those recommended for use - are
domestically produced. Overall, the unified base of road construction materials
and new technologies will enable our materials to compete internationally in
the future. Currently, we have around 190 developments, 70-80 of which are
being tested, and these are produced by Kazakh manufacturers,» noted Adiya
Zhumagulova, Head of the R&D Center, Kazakhstan Road Research Institute.
