Abstract
Mineral aggregate constitutes approximately 95% of hot mix asphalt by weight. The present study includes the determination of particle index based on fractured faces counts of coarse aggregate i.e. less than 2, more than or equal to 2 and more than 3 and its influences on marshall and fatigue properties of hot mix asphalt mixtures. The different particle index values ranging from 9 to 16 for the coarser size (19-13.2mm) have been determined and the same are used in the marshall mix design. The important factor for minimizing fatigue property of hot mix asphalt (HMA) mixture are, the fractured face count for coarse aggregate. The objective of the study is to evaluate the effect of particle index value on aggregate properties. Asphalt mix with crushed particles produces higher stability values with the increase in particle index value. The study also found that an increase in the amount of crushed particles causes decrease in unit weight and an increase in voids in mineral aggregate and optimum asphalt content. As fractured faces counts increases, the stiffness ratio (TSR) also increases. More the particle index value better will be the resistance to fatigue (Permanent deformation of the pavement).
