A Review on Evaluation Effect of Aggregate Gradation and Binder Parameters on Bituminous Mix Rutting

Bituminous pavements are composed of three components: aggregate, binder, and air. In the process of plant production and on site construction, the construction quality can vary in the three components and the variability can further affect a pavement’s future performance. This research identifies aggregate gradation, binder content, and air voids content as the fundamental parameters. Understanding the fundamental parameters influence on the Hot Mix Asphalt (HMA) mixture’s performance properties can provide valuable information on how to improve the current quality practice. The objective of this study is to investigate how mix gradation, air voids and small range binder content deviation from design binder content can affect, individually and collectively, the performance properties (rutting, cracking, and moisture susceptibility) of asphalt concrete in the context of construction variations.
