| Research Abstract |
This study investigated a rational volumetric mix design of hot mixed asphalt (HMA) mixture in order to improve durability of Japanese asphalt pavements. Design parameters of aggregates were selected to architect rigid aggregate structure with taking into account Japanese local resources, traffic, and weather conditions. A guideline of design parameters and their recommended values for deciding the appropriate balance of air voids and asphalt film was suggested. It was confirmed that the volumetric design method can design more durable HMA mixtures than the conventional Japanese method.
