Geotechnical, rock mechanics & pavement research

The geotechnical, rock mechanics and pavement (GR&P) research group at Victoria University focuses on fundamental and applied research that builds knowledge to make civil infrastructures safer, more economical and sustainable.

The group consists of leading researchers who apply innovation and creativity into research in a broad range of applications.

Our state-of-the-art testing facilities and numerical simulation tools allow us to conduct cutting-edge research that makes positive impacts on society and the environment in line with United Nation's Sustainable Development Goals.
