Effect of ageing on the morphology and creep and recovery of polymer-modified bitumens (2018)
Journal Article

Polymer additives are used to improve the properties of road bitumens including their oxidative resistance. However, their usage as anti-oxidative materials remains relatively unclear. This study aims to investigate the changes in the morphology and... Read More about Effect of ageing on the morphology and creep and recovery of polymer-modified bitumens.

Simulating plant produced material in the laboratory to replicate rheological and fatigue properties (2018)
Journal Article

As part of an effort by agencies and industry to move towards performance-based design to evaluate mixtures in the laboratory at a smaller scale before moving to full scale operation, laboratory protocols exist to simulate the aging that occurs as a...

The effects of laboratory ageing on rheological and fracture characteristics of different rubberised bitumens (2018)
Journal Article

Ageing of bituminous materials can result in loss of the durability of a flexible pavement. Using rubberised bitumens can enhance pavement performance while at the same time it solves a serious waste disposal problem. Combining Warm Mix Asphalt (WMA)...

Developing the multiple stress–strain creep recovery (MS-SCR) test (2018)
Journal Article

While most published work from Europe has been concerned with evaluating binders’ resistance to rutting based on their stiffness (deformation resistance), work originating in the US has mainly been concerned with ranking binders based on their recove...

Linear viscous approach to predict rut depth in asphalt mixtures (2018)
Journal Article

Rutting in asphalt mixtures is a very common type of distress. It occurs due to the heavy load applied and slow movement of traffic. Rutting needs to be predicted to avoid major deformation to the pavement. A simple linear viscous method is used i... Read More about Linear viscous approach to predict rut depth in asphalt mixtures.
