Rip rap shall consist of hard, dense, durable stone, angular in shape and resistant to weathering. <br />Rounded stone or boulders will not be accepted as rip rap material, The stone shall have a <br />specific gravity of at teas[ 2.5. Each piece shall have its geatest dimension not Beater than three <br />times its least dimension. If approved by CERTIFYING ENGINEER, removed concrete may <br />be used For rip rap provided it meets the other requirements of this section. <br />B. Material used for rip rap will be approved by CERTIFYING ENGINEER if, by visual <br />inspection, the rock is determined to be sound and dtuable.
