Maximum aggregate size can affect HMA, PCC and base/subbase courses in several ways. In HMA, instability may result from excessively small maximum sizes; and poor workability and/or segregation may result from excessively large maximum sizes (Roberts et al., 1996). In PCC, large maximum sizes may not fit between reinforcing bar openings, but they will generally increase PCC strength because the water-cement ratio can be lowered. ASTM C 125 defines the maximum aggregate size in one of two ways: 1

Asphalt products testing and inspection. Asphalt and asphaltic materials are tested to industry quality standards and for R&D support. Intertek asphalt laboratories perform analysis to global, industry and regulatory standards, including ASTM, AASHTO, ISO, EN, and other asphalt and petroleum industry criteria.

Recent advances in laboratory polishing and friction testing now provide a better assessment of friction that considers the entire gradation in an asphalt mixture rather than a single aggregate source. The dynamic friction tester (DFT) gives a better assessment of the friction of a pavement surface.
