Abstract
Project-specific quarrying of aggregate for asphalt manufacture has numerous advantages. With aggregate making up almost 95% of the materials that go into asphalt, the capital costs can balloon significantly when consequential costs such as additional trips generated by haulage are an uncontrolled variable. However, even with all this optimally resolved, there are still many considerations with degrees of varying influence that need to be managed and leveraged to fully realise the advantages of project-specific quarries.
The Upgrade of National Route 3 project by the South African National Roads Agency aims to achieve value through project-specific quarrying. The paper sets out the many considerations to achieve balance and sustainability in the initial selection of aggregate for asphalt for future use in asphalt recycling.
