Abstract

V diplomskem delu so predstavljene osnovne značilnosti ozelenjenih streh, konstrukcija le-teh, bitumen in polimer bitumen, ki se uporablja v ozelenjevanju streh, ter postopek kontrole mehanskih lastnosti bitumenskih trakov. Podrobneje smo raziskali vpliv staranja na bitumenske trakove, ki se uporabljajo za hidroizolacijo ozelenjenih streh pri nizkih temperaturah, ter določili mejo pri kateri vzorci bitumenskih trakov brez poškodb prenesejo upogib okoli trna z diametrom 30 mm, kot je to določeno s standardom SIST EN 1109:2000. Ugotovili smo, da bitumenski trakovi tipa IZOELAST P4 FLL plus s staranjem ne spremenijo meje, pri kateri so še odporni na upogib, ki se navezuje na standard SIST EN 1109:2000 in znaša -30 oC. Bitumenski trakovi tipa IZOTEKT P5 FLL plus pa s staranjem spremenijo mejo, pri kateri so še odporni na upogib, ki se navezuje na standard SIST EN 1109:2000. Pri vzdolžnih in prečnih novih vzorcih ta temperatura znaša -10 oC, medtem ko se pri staranih vzdolžnih vzorcih zniža na -5 oC, pri staranih prečnih vzorcih pa na +4 oC. Glede na relativno majhno število vzorcev, ki smo jih imeli na voljo za raziskavo (vzorci pridobljeni pri preizkusu na koreninsko odpornost), na podlagi rezultatov laboratorijskih meritev upogljivosti pri nizkih temperaturah zaradi staranja ne moremo z zanesljivostjo sklepati zaključke kakovosti bitumenskih trakov različnih debelin in bitumenskih mas (IZOELAST P4 FLL plus in IZOTEKT P5 FLL plus), kot tudi ne razlik v kakovosti posameznih bitumenskih trakov v prečni ali vzdolžni smeri.

Secondary title:	Control of mechanical properties of bitumen sheets for roof waterproofing with the emphasis on changing the flexibility at low temperature due to aging
Secondary abstract:	In this final thesis are presedented basic characteristics of green roofs, their construction, the bitumen and polymer bitumen, which is used for greening the roofs, and the procedure of controling mechanical properties of bitumen sheets. We have investigated the impact of aging on bitumen sheets, which are used for waterproofing of green roofs, at low temperatures, and determine the limit at which samples of bitumen sheets can take the flex around thorn with diameter of 30 mm, as defined by the standard SIST EN 1109:2000, without damage. We found, that bitumen sheets of IZOELAST P4 FLL plus type, do not change limit of flexibility with aging, as defined by the standard SIST EN 1109:2000, and it is -30 oC. Bitumen sheets IZOTEKT P5 FLL plus type, with aging change the limit, at which they are still resistant to bending, which is related to standard SIST EN 1109:2000. In the longitudinal and transverse specimen, which were new, is this temperature -10 oC. While with aged longitudinal samples is reduced to -5 oC, and with aged transverse samples to +4 oC. Because of small number of samples we had available for this study (samples obtained in the examination at the root resistance), limit temperatures are not data, from wich we can make conclusions about the quality of tested bituminous sheets of different thicknesses and bituminous mixtures (IZOELAST P4 FLL plus and IZOTEKT P5 FLL plus), nor differences in the quality of individual bitumen sheets in the transverse or longitudinal direction.
