Abstract: Tests were conducted on 25 percent unsurfaced slopes and 25 percent slopes surfaced with the depot inventory items, T17 membrane and M8A1 and M19 landing mats, to determine their effectiveness in support of wheeled and tracked vehicle traffic in tactical bridge access/egress roles. The T17 membrane would not satisfy any of the requirements alone but may be used in conjunction with the mats or other surfacings to waterproof the subgrade to achieve the surfacing requirements. The M19 mat will support all of the traffic required by the Letter of Agreement (LOA) but does not meet installation rates in either the assault vehicle egress role or the bridge equipment access role and will not provide sufficient traction when wet and muddy as required in the egress role. The M8A1 mat placed either normally or inverted will support the required traffic of the LOA. Inverted, the surface will provide adequate traction for the M113 armored personnel carrier to egress a stream where the bank is sloped 25 percent. The M8A1 mat placement rate will not meet any of the installation rates required in the LOA.
