Characterisation of non-standard granular aggregates including marginal crushed rocks and recycled crushed concrete as constructible pavement materials

The proper selection of aggregates to construct workable granular base materials requires deep understanding of behaviour of the materials. As there is a growing demand to use the locally available materials, which do not necessarily meet the specifications, it is necessary to understand and evaluate the performance of the non-standard materials. In this research a performance-based test method was adopted and modified to investigate the performance of the investigated materials. In-depth analysis of the results confirmed the capability of this test method in providing the essential information which are critical to understand the behaviour of unknown materials in pavement designs.
