There is a wider range of possible sources for a Type 2 than permitted for a compliant Type 1 aggregate - Type 2 may also be sourced from natural sands and/or gravels. This permeable base rock can be used in many applications where drainage is required. Class I Base Courses that are stabilized with cement must always be produced in a central mix plant. The interlocking capability of certain types of aggregates means that, even with a relatively thin sub base layer, the ability to carry heavy loads can be improved. 5.1 Clause reworded to improve clarity. To be classified as granular B gravel, 100% of the material must pass through a 150 mm sieve. A #1 aggregate is a nominal size of 3 to 1 inches and a #8 aggregate is a nominal size of 3/8 to 0.094 inch. 57 stone.
