Comparative Study of Aggregates for Flexible Pavement

Comparative Study of Aggregates for Flexible Pavement

1) Types of Aggregate: Aggregates can be classified to different categories Based on: a) Size of aggregates: Aggregate is usually described as either coarse aggregate (retained 4.75 mm) or fine aggregate (passing 4.75 mm). Aggregates generally make up about 95 percent of the total mass of hot-mix asphalt mixtures and 80 percent by mass of concrete
