Održivost i energetska efikasnost u kontekstu primene recikliranog agregata u proizvodnji asfaltnih mešavina

Abstract

Building industry presents one of the biggest pollutant producers, with simultaneous use of large quantities of natural materials. For this reason, in scientific cycles, in the last years analysis and testing of the possibilities of applying sustainable development principles during the production of building materials, have been performed. Special attention has been paid to the application of recycled concrete aggregate, having in mind that its consumption reduces the quantities laid on the waste fields. Within this paper possibilities of replacing 30% and 45% of natural stone aggregate with recycled concrete aggregate of the same fineness, in the production of asphalt mixtures for the base course has been analyzed. First, results of the standard test of asphalt mixtures were shown, and than the assessment of the energy savings during the mixture production has been presented.
