Aggregates for Pavement Construction


This course identifies the properties and characteristics of aggregates and how these relate to performance of pavement and surfacing materials.  It covers the systems for quarrying, storage, selection and handling, so that these properties are not altered and their quality remains consistent until placed in the pavement.
