Effect of hydrated lime and other mineral fillers on stiffening and oxidative ageing in bitumen mastic (2021)
Journal Article

The bituminous binder's ageing process is the primary reason behind the decrement in the pavement's in-service life, which can lead to cracking as a result of extreme hardening of the binder. In order to mitigate this problem, several methods have be... Read More about Effect of hydrated lime and other mineral fillers on stiffening and oxidative ageing in bitumen mastic.

The composition of the material phase responsible for the self-healing of macro-cracks in asphalt mortar beams (2020)
Journal Article

Self-healing of asphalt is assumed to be a flow process where bitumen flows into cracks to close them. Hence, the rheological behaviour of bitumen is one of the main factors affecting self-healing together with damage history, healing duration and pr...
