TRB's National Cooperative Highway Research Program (NCHRP) Report 555: Test Methods for Characterizing Aggregate Shape, Texture, and Angularity examines a methodology for classifying aggregates based on the distribution of shape, texture, and angularity characteristics. The report also explores a test method that it is appropriate for use in central and field laboratories, which measures shape, texture, and angularity characteristics of aggregates used in hot-mix asphalt, hydraulic cement concrete, and unbound base and subbase layers of pavements. Appendixes for the report were published as NCHRP Web-Only Document 80.
