3rd International Scientific and Professional Conference CORRIDOR 10 - a sustainable way of integrations industrijskih izvora zagađenja, tako i zagađenja od saobraćaja. Drumski saobraćaj je uzrok više od polovine emisija NOx i 35% emisija isparljivih organskih jedinjenja. Poseban problem u zagađivanju zemljišta čini emisija velike količine CO 2 , sumpor–anhidrida, različitih metala, ugljene kiseline. Industrijski objekti i saobraćajnice u degradaciji zemljišta učestvuju sa oko 25%. CFD metode simulacije širenja zagađenja su koristan i neophodan alat u planiranju i projektovanju velikih industrijskih postrojenja i velikih saobraćajnica, koje mogu da budu uzrok zagađenja vazduha i degradacije plodnog zemljišta u njihovoj okolini.

3rd International Scientific and Professional Conference CORRIDOR 10 - a sustainable way of integrations ECOTRACK - NEW TYPE OF BALLASTLESS TRACK SYSTEM Prof.dr.sc. Stjepan Lakušić Građevinski fakultet Sveučilišta u Zagrebu, Croatia Abstract Modern ballastless railway structures find ever wider use on conventional railway lines as well as urban tracks. In order to achieve better mechanical and durability properties of the ballastless railway structure and to preserve the environment through better waste management, on Faculty of Civil Engineering University of Zagreb was developed innovative concrete ballastless track prototype called ECOTRACK. In its nutshell, ECOTRACK is a concrete based solution that incorporates waste materials obtained during mechanical recycling of waste tyres. Application of recycled rubber assures this innovative type of track alignment with all relevant EU Directives in the field of waste management on one side, and on the other produce of the high performance concrete with enhanced resistance to impact loads, toughness, but also present degradation mechanisms. keywords: ballastless track, high performance concrete, tyre recycling, waste management, ECOTRACK – novi tip kolosijeka na betonskoj podlozi Sažetak Moderne kolosiječne konstrukcije na betonskoj podlozi bez zastora nalaze sve veću primjenu kako na konvencionalnim željezničkim trasama tako i na urbanim kolosijecima. U cilju poboljšanja mehaničkih i trajnosnih svojstava kolosiječne konstrukcije na čvrstoj podlozi te očuvanja okoliša poboljšanjem gospodarenja otpadom, na Građevinskom fakultetu Sveučilišta u Zagrebu razvijen je inovativni tip kolosijeka na betonskoj podlozi pod nazivom ECOTRACK. Kolosijek tipa ECOTRACK je betonska konstrukcija zasnovana na ideji korištenja produkata reciklaže automobilskih guma. Primjena reciklirane gume osigurava ovom inovativnom tipu kolosijeka usklađivanje sa svim relevantnim direktivama EU u području gospodarenja otpadom te dobivanja betona visokih uporabnih svojstava s poboljšanom otpornošću na udarna opterećenja, žilavost, ali i prisutne mehanizme degradacije. Ključne riječi: kolosijek na betonskoj podlozi, beton visokih uporabnih svojstava, reciklirana guma, gospodarenje otpadom Belgrade, 2012 310
