    (3) Main Types Of Aggregates Classification | Based On

    the aggregates possessing well-defined edges formed at the intersection of roughly planar faces are termed as angular aggregates (e.g., crushed rocks of all types). these types of aggregates have a maximum percentage of voids ranging from 38 to 40%. angular aggregates are superior to rounded aggregates from the following two-point of view are,5 aggregate specifications and requirements,coarse aggregates are divided into classes based on quality requirements as noted on the classification of aggregates table. class ap is the highest class and is assigned to aggregates which meet the requirements for all indot uses. some indot contracts specify type ap aggregates for use in on-grade application of portland cement concrete
