What aspect of asphalt mix design is evaluated by the Gyratory Compactor?

The Gyratory Compactor is a pivotal tool in asphalt mix design, primarily utilized to assess how a specimen behaves under conditions that mimic actual traffic loads. It achieves this by compacting an asphalt sample to a specified density, replicating the stresses and deformations that occur when vehicles travel over pavement.

This compaction method simulates the shear and compressive stresses experienced in the field, allowing for an evaluation of the specimen's density and stability. The results from this assessment can provide critical insights into the performance of the asphalt mixture, specifically regarding its resistance to deformation and potential for permanent change, which are essential factors in ensuring the longevity and durability of the pavement.

Other aspects, such as the visual aesthetics of the asphalt mixture, thermal properties, and price competitiveness, do not align with the primary function of the Gyratory Compactor. The focus of this equipment is strictly on mechanical performance rather than appearance, thermal characteristics, or cost considerations.
