Gyropac bulk density determination issues in South Australia

Asphalt supplied to the State Road Authority (SRA) in South Australia is designed to the Austroads Publication Series 4B requirements with several adjustments by the SRA specification. Monitoring by the SRA involves assessing air voids obtained by contractor production testing against target design air voids, and SRA also conduct comparison testing on audit samples to monitor contractor laboratory results. This paper details the outcomes of auditing undertaken by the SRA, and more specifically the discussions centred on the determination of the bulk density of asphalt by both the contractor and SRA and their respective laboratory requirements. A review of SRA laboratory procedures and recommendations for improvements to Australian Standards relating to bulk density determination including sampling and gyratory issues is provided.
