Stabilized unconsolidated fill materials and armor toe fill with clean rock ballast or brush to minimize erosion. Compact backfill material placed over culvert piping. Consider use of a geotextile underlayment or use of clean-swept ballast rock where stream bottom is unconsolidated and subject to erosion. Temporary Bridging Planning Avoid stream crossings where possible. Minimize the number of stream crossings.
Installation Use a bulldozer, knuckleboom loader, or skidder to install and remove dragline mats.
Keep heavy equipment out of stream. Keep mats' surface free of mineral soil and logging debris that could enter stream. Remove any debris which enters the stream at the crossing locations. Removal Clean off bridge surface. Remove mats by using mat cable loop or skidder grapple.
