Field compaction of gyratory designed asphalt mixes in South Australia

The design of asphalt mixes in South Australia is based on achieving a target air voids value using samples compacted in a Gyropac compactor. Production of these mixes is also checked on a regular basis to demonstrate that the target is being replicated in production. Gyratory compaction has been utilised for over ten years, and is used to design dense mix, open graded and stone mastic asphalts. The asphalt mixes are also checked for insitu air voids by taking cores from the pavement and evaluating their air voids immediately after construction. This paper presents this initial data and the air voids from a range of pavements after a period of trafficking to determine the level of post compaction.
