Fiberglass ACE Mat as a Temporary, Rapid Alternative to Unpaved Road Surfaces

Temporary, low-volume roadways often challenge designers with balancing cost of improving weak soils with the performance requirements of the intended application. Construction costs can be high, depending on the strength of the native soil and improvements required to sustain the vehicle loadings that are applied. In an effort to provide a solution for ground improvement that balances cost, logistics, and performance, the U.S. Army Corps of Engineers (USACE) developed a multipurpose, medium-duty matting system constructed of woven fiberglass reinforcement and polyester resin. This paper discusses three demonstrations in which the U.S. Army Corps of Engineers Mat (ACE Mat) was used as a surfacing for temporary roads. First, ACE Mat was used to support weak soil crossings for logging operations at the Apalachicola National Forest in Florida. Second, the matting was tested for its capability to support loads from a U.S. Marine Corps Medium Tactical Vehicle Replacement (MTVR) and a U.S. Army M1 Abrams main battle tank crossing sand and silt soils at the U.S. Army Engineer Research and Development Center in Mississippi. Finally, ACE Mat was demonstrated as a ground surfacing to stabilize a riverbank during temporary bridging training at Fort Knox, Kentucky. Attributes and performance characteristics of ACE Mat in comparison to typical unpaved road design and construction using compacted aggregate are also discussed.
