High modulus asphalt concrete for Ljubljana airport apron

摘要

Central part of the main apron at the Ljubljana airport from 1978 was scheduled for reconstruction in 2014 because of the increased traffic loads and subsequent distress of the existing asphalt pavement. Because of the traffic situation and faster completion time the asphalt pavement was chosen for the reconstruction and for the planned high traffic loading and severe climatic conditions a suitable asphalt mix had to be selected. A high stiffness modulus asphalt mix was chosen for base layers and the article describes the mix design, its testing and finally completed reconstruction of the airport apron area.
