Abstract

Asfalt e eden na pomembnejših gradbenih materialov. Znotraj evropskega cestnega omrežja je okrog 6,1 milijona kilometrov asfaltiranih cest, ki povezujejo tako večja urbana središča kot tudi majhne skupnosti. Obrabne asfaltne plasti voziščnih konstrukcij so najbolj neposredno izpostavljene prometnim in klimatskim obremenitvam. Prevzeti in prenesti morajo različne sile, ki jih ustvarjajo vozila na vozni površini, ter hkrati zaščititi voziščno konstrukcijo pred vremenskimi vplivi. Tovrstne obremenitve zahtevajo neprekinjeno spremljanje strokovnega razvoja na področju asfaltov ter zagotavljanje kakovosti asfaltne zmesi in voziščnih konstrukcij, s čim manjšimi stroški proizvodnje, vgradnje, vzdrževanja in razgradnje. Intenzivna izgradnja avto cest in pripadajoče infrastrukture v obdobju med 1995 in 2010 v Sloveniji je pozitivno vplivala tudi na industrijo asfalta, ki se je vztrajno razvijala. Po letu 2008 se je proizvodnja asfaltnih zmesi drastično znižala in s tem prizadela asfaltne obrate. V magistrskem delu je predstavljeno, na kakšen na in asfaltni obrati določajo ceno asfaltnim zmesem obrabnih plasti. Glede na to, da so asfaltne zmesi obrabnih plasti s polimeri modificiranimi bitumni občutno dražje od asfaltnih zmesi obrabnih plasti z uporabo navadnih cestogradbenih bitumnov, je izvedena stroškovna analiza, na podlagi katere je razvidno, ali je višja cena le-teh upravičena, saj se na podlagi te razlike v ceni v praksi velikokrat dogaja, da se uporabi cenejša asfaltna zmes, ne glede na morebitne negativne posledice.

Secondary title:	Cost analysis of asphalt mixtures of surface layers
Secondary abstract:	Asphalt is one of the major construction materials. Within the european road network there are around 6.1 million km of paved roads, linking major urban centers as well as small communities. Surface layers of asphalt pavements are most directly exposed to traffic and climate loads. They have to undertake and transfer different forces that are generated by vehicles driving on the surface and at the same time protect the pavement from the weather effects. Such loads require continuously monitoring of professional development in the field of asphalts and ensuring the quality of asphalt mixtures and pavements with minimizing the cost of production, laying, maintenance and recycling. Intensive construction of motorways and associated infrastructure between 1995 and 2010 in Slovenia had a positive impact on the asphalt industry, which was constantly developing. After 2008 the production of asphalt mixtures drastically reduced, thereby affecting the asphalt plants. The Master’s thesis presents how asphalt plants determine the price of asphalt mixtures for surface layers. Due to the fact that the asphalt mixtures for surface layers with use of polymer modified bitumen are significantly more expensive than asphalt mixtures using a conventional bitumen, the cost analysis carried out show whether the higher cost is entitled, because in practice often happens, due to these price differences, that cheaper asphalt mixtures are used, regardless of negative consequences.
