HOW TO CLASSIFY AGGREGATES ACCORDING TO SIZE
Jul 07, 2014 Crushed Gravel Sand it is the fine aggregate produced by crushing natural gravel. According to size the fine aggregate may be described as coarse sand, medium sand and fine sand. IS specifications classify the fine aggregate into four types according to its grading as fine aggregate of grading Zone-1 to grading Zone-4.
DIVISION II MATERIALS

The AASHTO system ranks specs according to size (1-10), with 1 being the largest (all material must pass a 4 sieve) and 10 being the smallest (all material passing a 3/8 sieve). Multi-digit specs represent a blend of one or more of the ten basic specs (i.e. AASHTO 57 is a blend of AASHTO 5 and AASHTO 7).
