STP 1412 focuses on the effect of aggregate properties on HMA performance and covers a wide range of aggregate characteristics. Valuable information is presented on performance of HMA designed with Superpave protocols and criteria for both mixtures and aggregates.

12 papers address:

• Aggregate polishing as a safety concern

• Contribution of the mineral aggregate components to rutting resistance

• Superpave coarse and fine gradations

• Validity of the restricted zone

• Maximum aggregate sizes

• Amount of dust, particle shape, and coarse and fine aggregate particle angularity.

This book is a valuable resource for everyone in the paving industry that produces, specifies, and uses aggregates.
