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.
