Nahar, S.N. (author)During the service life of flexible asphalt pavements, asphalt concrete degrades due to traffic loading and environmental conditions like temperature, rain, oxidation, ultraviolet-radiation from the sun. All these environmental factors have adverse effects on the performance of bitumen, which is the binder of asphalt concrete. They are known to...doctoral thesis 2016

Pauli, A.T. (author)As a contribution to the development of mutli-scale multi-physics approaches to modelling pavement performance, the present thesis considers the topic of damage accumulation accompanied by damage recover self-healing of the bituminous asphalt phase of pavement systems. It is found insightful that by adopting Hveem’s [1943] concept of attributing...doctoral thesis 2014

Liu, Q. (author)Porous asphalt shows excellent performance in both noise reduction and water drainage. Although porous asphalt has these great qualities, its service life is much shorter (sometimes only half) compared to dense graded asphalt roads. Ravelling, which is the loss of aggregate particles from the surface layer, is the main damage mechanism of porous...doctoral thesis 2012

Van den Bergh, W. (author)Nowadays, reclaimed asphalt aggregate is often used in new asphalt mixtures. In Flanders, up to 50 % of the binder content is allowed to be originating from reclaimed asphalt. However, the effect of this aged binder on the fatigue and healing properties of the asphalt mixture is questioned. A procedure for the ageing of asphalt mixtures, mortars...doctoral thesis 2011
