Standard Practice for Specifying Standard Sizes of Stone for Erosion Control

Importancia y uso:

5.1 The standard size designations listed in this practice are provided so that the design team, consumer, and the producer have a common reference in sizing stone materials used in erosion control. The design team should assign a materials survey, and rock quality testing series to determine which quarry sources may have suitable blasting and processing procedures to produce the required gradations. The design team should recognize the fact that not all sources are capable of or willing to produce the required gradations. Only those sources listed by the design team should be considered for construction of the project.

5.2 The standard size designations provided in this guide are suitable for protective surfacing and structures designed for erosion control. These sizes are for typical structures such as jetties, revetments, groin baffles, bulkheads, lining for drainage/irrigation ditches and for intake or outlet facilities, bridges and stream channel banks, gabions, and slope protection for earth embankment and rock-fill dams.

5.3 The design selection of stone sizes, durability, placement, filter/bedding materials, or geotextiles, steepness of slopes for placement, and layer thickness are beyond the scope of this guide.
