ERTRAC National Platforms Workshop Division for Roads and Bridges Units: Laboratory for Asphalt, Concrete and Geotechnique Attestation Bureau Controlling Bureau Round Robin Test Organizing Bureau
ERTRAC National Platforms Workshop Some research (development) works a.) Management I. PMS II. BMS (PONTIS adaptation) III. Asset management b.) Cement concrete pavements I. Jointed pavement II. CRCP III. Whitetopping c.) Industrial by-products Blast furnace slag for embankment
ERTRAC National Platforms Workshop • PMS • Network level PMS in 1990’s(Markov matrix, funds distribution, funds need, national economy loss when changing) • HDM-4 adaptation(also for network level, NUP-National Road Rehabilitation Programme for 2009-2020)
ERTRAC National Platforms Workshop BMS American PONTIS-adaptation (Bridge survey methodology, bridge elements, intervention techniques, unit prices, deterioration models). Further development: combination of the deterioration of neighbouring elements; higher level optimization) Use in NUP
ERTRAC National Platforms Workshop Asset Management I. Preparation of Hungarian Road Asset Management Users’ need +owner’s requirement (questionnaire survey) Administrative measures (three-level quality control system, decentralisation of road management, trunk road network)
ERTRAC National Platforms Workshop Asset Management II. Business arrangement (PPP, also in road maintenance) Decision supporting technical tools ( yearly condition survey since 1979, assets valuation since 1981, road or infrastructure management system)
ERTRAC National Platforms Workshop Jointed cement concrete pavements 1976-1999 No concrete pavements in Hungary 1999-2002 Laboratory tests, experimental sections with exposed aggregate surface 2003- Concrete pavement on road ringM0 Continuously reinforced concrete pavements Experimental sections between 1999-2002 (punch-out problems)
ERTRAC National Platforms Workshop Whitetopping (thin cement concrete layer)Laboratory investigations, first test section in 2007 (120 mm, intensive heavy traffic) -
Industrial by-products in road construction Fly ash and blast furnace slag (bottom ash) 700 000 m3 slag in the embankment ofmotorway M6 (2005) Environmental monitoring (CrVI content) Dense and durable (80-100 MPa) ERTRAC National Platforms Workshop
