Use of recycled asphalt in the bituminous base course

U radu su opisana ispitivanja mogućnosti primjene recikliranog asfalta u proizvodnji asfaltnih mješavina. Ispitivanjima u laboratoriju istražena je pogodnost za primjenu recikliranog asfalta te projektiran sastav asfaltnih mješavina BNHS-22 s 10%, 15% i 20% recikliranog asfalta nakon čega je izvedena pokusna proizvodnja projektiranih asfaltnih mješavina. Dobiveni rezultati omogućili su donošenje zaključaka o primjenjivosti i potrebnom udjelu recikliranog asfalta, tehnologiji proizvodnje te mogućim uštedama u proizvodnji novih asfaltnih mješavina.Possibilities for using recycled asphalt in the asphalt mix manufacturing process are described in the paper. The applicability of recycled asphalt was tested in laboratory, and asphalt mixes BNHS-22 containing 10 %, 15 % and 20 % of recycled asphalt were designed. The trial production of asphalt mixes designed in this way was then operated. The results obtained have lead to conclusions about the applicability and necessary proportion of recycled asphalt, manufacturing technology, and possible savings in the manufacture of new asphalt mixes
