Dennis Selse, Technical Manager at the Swedish company Nouryon, presented international experience with this technology, which enables the restoration of aged pavements by incorporating up to 30% of new material.

The method is widely used in Sweden on low-traffic roads (ranging from 500 to 2,000 vehicles per day), currently being tested in France, and already applied in Ukraine. The main objectives of its implementation are to reduce carbon dioxide emissions and enhance the environmental sustainability of road construction.

According to the expert, the technology is particularly effective for old and heavily worn pavements. After the recycling process, a layer of hot asphalt concrete or a thin wearing course is applied. In Sweden, such roads have a service life of up to 15–20 years before requiring major maintenance.

During the discussion, specialists from JSC “KazdorNII,” JSC “NC KazAvtoZhol,” and contracting organizations of the Almaty region exchanged views on the potential adaptation of the technology to Kazakhstan’s conditions. It was noted that during the production of the mixtures, it is crucial to control the blending process of reclaimed material to prevent secondary crushing, which can adversely affect the strength of the final mix.
