Kazakhstan is experiencing widespread road damage due to an intense heatwave, with asphalt and cement concrete surfaces warping in both southern and northeastern regions of the country. The national road operator KazAutoZhol has stated that such deformation is a normal response to extreme heat conditions.
Air temperatures have soared above 35°C across most regions, prompting meteorologists to advise residents to avoid going outdoors during peak daylight hours. The most affected areas are inter-city highways, where the heat has caused significant stress on infrastructure.
The first reports of road warping emerged from the Pavlodar Region in northeastern Kazakhstan. On June 13, local authorities conducted emergency repairs at kilometer 1,265 of the Astana-Shiderty-Pavlodar-Uspenka-Russian border highway. Concrete slabs had buckled following a sharp temperature increase to 33-35°C.
Notably, this highway is a toll road, and the damage drew criticism from motorists. Shortly thereafter, similar issues were reported in the south. On June 19, KazAutoZhol announced repairs on the Shymkent, Uzbekistan border highway, specifically at kilometer 763, another toll section. The pavement there had deformed due to air temperatures reaching 40-45°C.
On the same day, further damage was reported on the Astana-Pavlodar highway in central Kazakhstan, where several consecutive days of temperatures between 32-35°C contributed to the melting and lifting of concrete slabs.
“Cement concrete pavements are particularly sensitive to sudden temperature changes,” experts from KazAutoZhol explained. “In hot conditions, the slabs expand. If gaps between them are insufficient or joints are compromised, internal stress can cause the slabs to suddenly lift, a phenomenon commonly referred to as a ‘blow-up.’ This is typical in regions where daytime temperatures exceed 35°C, which includes much of southern and central Kazakhstan.”
KazAutoZhol also cited similar challenges in other countries, noting that in the United States, states like Minnesota, Wisconsin, and Illinois report comparable incidents nearly every summer.
The organization operates under the Ministry of Transport of Kazakhstan, which recently saw a leadership shake-up. In mid-May, President Kassym-Jomart Tokayev reprimanded then-Minister Marat Karabayev for multiple failings within the transport sector. Karabayev was dismissed in early June, and his deputy, Maksat Kaliakparov, was appointed acting minister.
As previously reported by The Times of Central Asia, construction began this month on the strategic Center-West highway corridor, part of the Trans-Caspian International Transport Route (TITR), a key freight link connecting China and Europe via Kazakhstan.
