Cold recycling of asphalt pavements using foamed bitumen and cement

U radu je prikazan tehnološki postupak hladnog recikliranja asfaltnog kolnika na licu mjesta primjenom upjenjenog bitumena i cementa na obnovi kolničke konstrukcije državne ceste D1, na dionici Knin – Biskupija. Prikazanim tehnološkim postupkom ostvaruje se visoki postotak iskoristivosti materijala iz postojeće kolničke konstrukcije čime je smanjena potreba za prirodnim materijalima. Obnovljena kolnička konstrukcija s analiziranim postupkom ima potrebnu nosivost, monolitnost te otpornost na smrzavanje.The technological procedure of in-situ cold recycling of asphalt pavement, using the foamed bitumen and cement during pavement structure rehabilitation works on the Knin – Biskupija section of the D1 National Road, is presented in the paper. The technological procedure presented in the paper enables high percentage of material recovery from the existing pavement structure, and thus the need to use natural material is reduced. The pavement structure rehabilitated using the studied procedure has an appropriate bearing capacity, monolithic properties, and resistance to freezing
