Development of standards and regulations

Activity in technical committees

• Ing. Adrián Fonód, PhD., TC 94 Road construction
• Ing. Michaela Sláviková, TC 75 Stone and aggregates

VUIS – CESTY, spol. s r. o. cooperates closely with the Slovak Office of Standards, Metrology and Testing. Participation in committees, research activity and links to construction organisations active in road construction are applied in the preparation of new national technical standards (STN) as well as their revised versions. Our staff also actively participate in the translation of European standards (EN).

Translations of European standards we have contributed to

• STN EN 13108-20, Bituminous mixtures. Material specifications. Part 20: Type testing
• STN EN 13877-3, Concrete pavements. Part 3: Specifications for dowels to be used in concrete pavements

Technical regulations

Research activities focused on new materials and technologies in road construction are continuously reflected in technical regulations, technical conditions, technical and quality conditions and material catalogue sheets, which are prepared by professional entities on the basis of orders from the Slovak Road Administration.

These regulations apply to structures within the remit of the Slovak Road Administration and the National Motorway Company. Since 2004, they have been approved and issued by the Ministry of Transport of the Slovak Republic. They are available free of charge on the SSC website and are used by a wide group of designers, investors, contractors, construction supervisors and other professionals.

• TKP 6, Compacted asphalt mixtures (revision)
• TKP 7, Mastic asphalt (revision)
• TP, Use of gritting materials for winter road maintenance (November 2021)
• RÚ, Analysis of the possibility of using asphalt mixtures in road tunnels in terms of their fire safety (November 2021)
