New GOST standards for temporary roads and asphalt concrete have come into force in Russia

Russia has developed new GOST standards with rules for the design of temporary highways and asphalt concrete for public roads, which came into force on October 1.

Cast mixes and asphalt concrete can now be designed for a variety of traffic conditions, including normal, heavy, extreme heavy, pedestrian, bicycle and motor vehicle traffic.

GOST for temporary roads establishes design rules for sections constructed for the period of construction, reconstruction, major repairs and repairs of public roads, and divides such roads into bypass and access roads, as well as into four categories depending on traffic intensity.

MOSCOW, October 1 - RIA Novosti. New GOSTs with rules for the design of temporary highways and asphalt concrete for public roads were developed in Russia; they came into force on October 1, it follows from materials of Rosstandart, which RIA Novosti reviewed.

Cast mixtures and asphalt concrete can now be designed for normal, heavy, extremely heavy traffic conditions and for pedestrian, bicycle and motor vehicle traffic. Depending on the performance of the pavement, individual compositions for the road surface are selected. The mixture recipe contains the type and type, traffic conditions, the name of the object where the installation will be carried out, the temperature range for preparing the mixtures, and more.

In turn, GOST for temporary roads establishes design rules for sections constructed for the period of construction, reconstruction, major repairs, repairs and during the maintenance of public roads. The requirements of this standard do not apply to temporary non-public roads; areas constructed for road work on roads located within the boundaries of populated areas; as well as on winter roads and ice crossings.

Based on their functional purpose, temporary roads are divided into bypass roads and access roads. In addition, such structures are divided into four categories depending on the average daily volume of vehicle traffic. At the same time, temporary roads due to their service life may be subject to dismantling or transfer to public roads on a permanent basis.

The construction of temporary bypass roads should be provided when carrying out work on reconstruction, major repairs or maintenance of roads if it is necessary to close the roadway in width by more than 50%. When designing such roads, it is necessary to take into account the terrain, the layout of the area's transport network, traffic capacity and environmental requirements. Depending on the category of temporary roads and the terrain, speed limits can vary from 20 to 70 kilometers per hour.
