ASTM D5821-13 (R2017) PDF Download

The ASTM D5821-13 (R2017) standard provides a procedure for evaluating the acceptability of coarse aggregate in relation to requirements for percentage of fractured particles. This standard is applicable in various construction applications, including maximizing shear strength, providing stability for surface treatment aggregates, and enhancing friction and texture for aggregates used in pavement surface courses.

The standard indicates that specifications may vary in terms of the number of fractured faces required on a fractured particle, as well as whether the percentage should be determined by mass or count. In cases where the specification does not specify, the criterion of at least one fractured face is used, and the percentage is calculated by mass.
