Update of the interstate standard “Reinforced concrete slabs for tramway track pavements”

Introduction. Development of urban public transport networks in Russian cities involves modernization and improvement of rail transport to increase its traveling comfort, carrying capacity and reliability. Tram transport is environmentally friendly and has a high passenger capacity. The combination as well as the intersection of rail and pneumatic transport in the urban environment is considered to be an urgent issue. In this regard, State Standard 19231 “Reinforced concrete slabs for tramway track pavements. Specifications” is needed to be revised and updated due to changes in the requirements for concrete and emergence of new classes of steel reinforcement.

Aim. To update State Standard 19231 in order to bring products for tram infrastructure to the proper regulatory and technological parameters in compliance with current requirements.

Materials and methods. The present study involves an analysis of existing regulatory documents in the field of reinforced concrete materials and products, as well as a bibliographical research of works and expert opinions.

Results. Updating the standard resulted in the establishment of specifications that meet the current demand, both in terms of regulations and scientific research.

Conclusions. The updated interstate State Standard 19231 will contribute to a higher quality design and production of reinforced concrete slabs for tramway pavements, which will surely enhance their reliability and durability.
