dc.description.abstract	The deterioration of the aggregate material used in road construction is of concern as it affects the overall long term stability of the road pavement and should be minimised by using durable aggregates. The paper presents proof of concept of an experimental system, developed to assist in the evaluation of aggregate quality, using a customised rolling model drum, in which the aggregate assemblage is subjected to different stress levels by using the geotechnical centrifuge modelling technique. The outcome of the study has demonstrated the operation and functionality of the system and the potential to quantify aggregate durability solely dominated by particle-to-particle interaction mechanism.
