Sieve analysisGradation testing, also called sieve analysis, is a fairly basic yet essential test that measures the gradation (or distribution of aggregate particles, by size, within a given sample) to determine whether it’s compliant with design, production control requirements, and verification specifications.www.arlynscales.com/industrial-scales/asphalt-aggregate-gradation-and-size-te…Gradation and Size - Pavement Interactive
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 … See more
