Crushed Gravel #2: Approx 1½ ″ to 3″ Wide. Crushed rocks in grade no. 2 usually range from 1½ inches to 3 inches in diameter, so, depending on your supplier, may contain larger gravel stones that, like #1, are not easy to work with and will need to be moved as individual pieces. Uses of gravel #2 include the following:
The graded coarse aggregate is defined by its nominal size i.e., 40 mm, 20 mm, 16 mm, 12.5 mm, etc. For example, a graded aggregate of nominal size 12.5 mm means an aggregate most of which passes the 12.5 mm IS Sieve. Because the aggregates are formed due to natural disintegration of rocks or by the artificial crushing of rock or gravel, …
