Development of standards and regulations

Activity in technical committees

• Ing. Adrián Fonód, PhD., TC 94 Road construction
• Ing. Michaela Biela, 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

• TNI CEN/TR 17499 Bitumen and bituminous binders. Examples for CE marking and declaration of performance (DoP)
• STN EN 12597 Bitumen and bituminous binders. Terminology
• STN EN 12697-5 Bituminous mixtures. Test methods. Part 5: Determination of the maximum density
• STN EN 12697-26 Bituminous mixtures. Test methods. Part 26: Stiffness
• STN EN 12697-30 Bituminous mixtures. Test methods. Part 30: Specimen preparation by impact compactor
• STN EN 13108-1 Bituminous mixtures. Material specifications. Part 1: Asphalt concrete
• STN EN 13108-2 Bituminous mixtures. Material specifications. Part 2: Asphalt concrete for very thin layers
• STN EN 13108-5 Bituminous mixtures. Material specifications. Part 5: Stone mastic asphalt
• STN EN 13108-8 Bituminous mixtures. Material specifications. Part 8: Reclaimed asphalt
• 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

Departmental 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.

Of the currently valid departmental technical regulations, we have contributed to the following:

Technical and quality conditions (TKP)

• TKP 22 Waterproofing system of pavements on bridges
• TKP 7 Mastic asphalt
• TKP 36 Slurry seals
• TKP 37 Asphalt-cement pavement layers
• TKP 39 Artificial dense aggregate from blast furnace slag

Technical conditions (TP)

• TP 027 Design of strengthening of concrete bridges and rehabilitation of concrete structures
• TP 039 Use of gritting materials for winter maintenance of roads
• TP 107 Diagnostics of the condition of the earthworks and pavement drainage
• TP 101 Methodology for determining the stiffness of asphalt mixtures
• TP 084 Performing and evaluating detailed visual inspections of asphalt pavements
• TP 083 Catalogue of asphalt pavement distresses
• TP 079 Design and construction of additional traffic lanes, pavement connections and transverse trenches in roads
• TP 071 Inspection, maintenance and repair of roads. Motorways, expressways and roads
• TP 058 Strengthening of asphalt pavements
• TP 047 Catalogue of technologies for repairing basic types of pavement distresses
• TP 046 Cold in-place recycling of flexible pavement layers
• TP 044 Hot in-place recycling of asphalt mixtures for pavements with traffic load classes II to VI
• TP 036 Methodology for determining the water sensitivity of asphalt specimens according to STN EN 12697-12
• TP 033 Design of flexible and semi-rigid pavements
• TP 002 Catalogue of pavement structures for an axle load of 115 kN

Material catalogue sheets – supplement to TKP

• KLEaZ 1/2021 Catalogue sheets of emulsions and joint sealants
• KLHS 1/2016 Catalogue sheets of hydraulic binders
• KLVM 1/2010 Catalogue sheets of pavements on bridges

Analytical studies (RÚ)

• RÚ – Refinement and extension of measures to control or eliminate reflective cracking in semi-rigid asphalt pavements (2025)
• RÚ – Analysis of the possibilities of using asphalt mixtures in road tunnels in terms of their fire safety (2021)
• RÚ – Asphalt mixture type PMAZ (polymer-modified asphalt mixture) – an alternative to asphalt mixtures with the modified binder PmB (2020)
• RÚ – Revision of selected product standards of the EN 13108 series and related changes in national regulations (2016)
• RÚ – Detailed analysis of the basic provisions for pavement design (2015)
• RÚ – Analysis of measurement outputs of variable pavement parameters on long-term monitored sections (2015)
