2. Ageing of Asphalt Mixtures : Micro-scale and mixture morphology investigation
Abstract : There are many variables that affect the viscoelastic properties of asphalt mixtures with time, among which age hardening may be considered one of the important ones. Age hardening of asphalt mixtures is an irreversible process, which contributes to a reduction of the durability of pavements and eventually increases the maintenance cost. READ MORE

3. Flow-induced Surface Defects and Ageing Behaviour of Injection-moulded Polymers
Abstract : Injection moulding is one of the most commonly used manufacturing methods for the production of polymer-based components such as car bumpers and other automotive details. The surface appearance of these products is of great importance since it is directly connected to the perceived quality. READ MORE
