Abstract

The performance of an asphalt mix can be assessed by visual on-site inspections over a period of time that demonstrate to the trained eye that there is an overall structural functioning of the mix. The assessment is basically asking the question whether the mix is leaning on the dry and rut resistance side or on the wet and fatigue resistant side of the optimum for the traffic category in question. The integrity of an asphalt mix design requires the above performance assessment to be supported by a specification appropriate to the application, a mix register, monitoring of the production process, mix performance testing, interlaboratory proficiency testing and auditing. This paper discusses a sequence of steps being undertaken within the state road authority of South Australia to maintain the integrity of an asphalt mix and to ensure that correct target parameters are specified and consistency exists amongst all asphalt suppliers to provide the highest level of quality to asphalt pavements for the benefit of the road users.
