SECTION 31 37 00 RIPRAP, BOULDERS, AND BEDDING PART 1 GENERAL SECTION INCLUDES A. The WORK includes excavation, grading, and installation of riprap, boulders, soil riprap, void-filled riprap, and bedding placed at the locations shown on the DRAWINGS. The materials to be used and the construction of such structures shall be as specified herein.

One of the hazards of placing a highway near a river or other water body is the potential for erosion of the highway embankment by moving water. perform a field test, the contractor shall provide a sample of the proposed rock riprap material meeting the gradation for the specified size class. Gradation field tests shall follow the equal interval test procedure in NCHRP Report , Section , or ASTM D , or the modified equal interval method.

Riprap is usually solid durable limestone rock, which is generally resistant to erosion and to normal stream chemistry. Riprap material that is of questionable origin should be given a sodium sulfate soundness test to determine its durability.

Riprap material should have a specific gravity of at least COLUMBUS, Miss. (Feb. 6, ) – Thirty years after the dedication of the Tennessee-Tombigbee Waterway, officials cut another ribbon today dedicating a museum that provides education outreach and features the value of transportation within the historical inland passageway built by the U.S.

Army Corps of Engineers from to Slopes approaching may require special stability analysis. The inherent stability of the soil must be satisfactory before riprap is used for surface stabilization. Outlet Protection – Design criteria for sizing stone and determining dimensions of riprap aprons are presented in Standards and Specifications for Rock Outlet Protection.

The Nashville District dedicated the mile divide section of the Tennessee-Tombigbee Waterway and the Bay Springs Dam and Lock in Dennis, Miss., May 6, Secretary of the Army John O. Marsh Jr. and Governor Wallace presided over the dedication of the entire waterway June 1, in Columbus, Miss., which symbolically merged the waters of.
