Gazprom Neft has completed deliveries of high-tech bitumen materials for repairing the road surface on the A-128 St Petersburg—Morye highway, which follows the route of the legendary WWII Siege of Leningrad “Road of Life”. The resurfaced section of the Road of Life, repaired as part of the national “Safe and High-Quality Roads” project, was commissioned on 30 April, the day before the 75th anniversary of the country’s victory in World War II (known in Russia as the “Great Patriotic War”).
More than 25,000 tonnes of asphalt mix (containing Gazprom Neft bitumen binders, increasing warp resistance and ensuring functionality at temperatures of −28—+76°С) was laid during construction of the nine-kilometre section of the route.
In order to increase the service life of the road-surface, the asphalt covering was enhanced with Superpave volumetric mix design technology, taking local traffic loads and climatic conditions into account.* More than 20 km of Gazprom Neft Brit-brand polymer-bitumen tape were used in sealing joints in this asphalt road covering.
Gazprom Neft is, today, the largest supplier of polymer-bitumen binders (PBBs) to roadbuilding businesses in Russia’s North—West Region. In 2018, at that year’s St Petersburg International Economic Forum (SPIEF), the company entered into an agreements with the Governments of St Petersburg and the Leningrad Oblast on cooperating in supplying high-tech bitumen products to these regions. The operator on these agreements is Gazpromneft-Bitumen Materials, which is actively involved in implementing major infrastructure projects to develop the transport network in St Petersburg and the Leningrad Oblast. The company’s bitumens are being used in road coverings for the M-11 Neva motorway, the A-121 Sortavala highway, the A-191 Scandinavia highway, the Western High-Speed Diameter, the St Petersburg Ring Road, Nevsky Prospect, and elsewhere.
The “Road of Life” was the only route on which transport connections were possible during the Siege of Leningrad, with the route being in operation from September 1941 to March 1943.
* “Superpave” or “Superior Performance Pavements” refers to a method for designing enhanced-performance asphalt mixes for road coverings. This technology was developed in the USA and was the result of many years’ research into increasing the useful service life of asphalt road surfaces.
