Rip mp shall consist of hazd, dense, durable stone, angulaz 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 least 2.5. Each piece shall have its greatest dimension not greater 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 mp will be approved by CERTIFYING ENGINEER it; by visual <br />inspection, the rock is detemtined to be sound and durable.
