Modelling biocementation of recycled sand and demolition wastes for pavements

Project Leader: Guillermo Narsilio

Keywords: civil infrastructure; computational materials science; finite element modelling; geotechnical engineering; physical modelling
Disciplines: Infrastructure Engineering

This project aims to develop biocements with recycled sand and demolition wastes as road construction materials. The usage of these low-carbon waste materials in pavement projects can significantly reduce carbon emissions and costs. This research expects to generate new knowledge on the performance of recycled wastes in roads, when subjected to high traffic loads using experimental, numerical approaches and field trials. Expected outcomes include evaluating and modelling the performance of biocements and demolition materials in roads, and building enduring collaborations with industry. Benefits include: diversion of wastes from landfills, reduction in carbon emissions and the potential commercialisation of recycled wastes for road projects.

The PhD students (Graduate Researchers) based at the University of Melbourne will focus on numerical modelling for which a basic understanding of consitutive modelling and some coding/programing skills are desirable. Experience with Python or Matlab and with Comsol Mulitphysics is a plus.
