The Proposed Standard Specification for Standard Sizes of Quarried Stone for Erosion Control is a new specification currently being developed by ASTM Subcommittee D18.17 on Rock for Erosion Control. The proposed specification contains standard size designations and maximum permissible ranges in weight or mechanical analyses for standard sizes of (1) graded quarry stone or riprap and (2) filter bedding stone for use in erosion control structures. A total of seven standard sizes are included for graded quarry stone, and three standard sizes are included for filter bedding stone. The proposed standard sizes were developed to provide the designer, the consumer, and the producer with a common reference in connection with the sizing of quarried stone materials used to control erosion. Use of standard gradations versus nonstandard gradations should be evaluated for each major project, and standard gradations should be utilized whenever cost-effective.
