Abstract: A culvert bundle and fill assembly for stream crossings and flow-through bridge abutments comprising: (a) a first separator fabric; (b) a plurality of culverts placed on the fabric adjacent to one another along their lengths; (c) a plurality of triangular cross-section blocks placed in pairs in upper and lower spaces between adjacent culverts; (d) a plurality of fasteners placed around the plurality of culverts and blocks for holding the culverts and blocking in position; (e) a second separator fabric placed over the plurality of culverts and blocks; and (f) soil or other fill placed over the second separator fabric and the plurality of culverts and blocking to create a road or other crossing structure surface.

Abstract: This invention relates to road construction and, more particularly, culvert bundles that are used in the construction of roads or other structures across streams and rivers. A culvert bundle and fill assembly for stream crossings and flow-through bridge abutments comprising: (a) a first separator fabric placed over a streambed; (b) a plurality of culverts placed on the fabric and blocked into position; (c) a plurality of bands, cables, strapping fasteners or other restrainers holding the culverts and blocking in position; (d) a second separator fabric placed over the plurality of culverts; and (e) soil or other fill placed over the second separator fabric and the plurality of culverts and blocking to create a road or other crossing structure surface.

Abstract: This invention relates to a novel design of an open bottom box culvert which can be used to enable roads, highways and other infrastructure to cross streams without infringing on the wetted perimeter of a stream or interrupting the stream gradient. More particularly, this invention pertains to an innovative use of mineral soil (clay, silt, sand, gravel, cobbles, boulders, broken rock, ice or mixtures of any or all of the foregoing), concrete or wood abutments and metal such as steel, and in some cases geosynthetics, to construct an open bottom box culvert structure which can be erected over a stream or creek and enable vehicular loads and other infrastructure to cross the stream or creek.

Abstract: This invention relates to a novel design of reinforced soil arch which can be used to construct bridges, overpasses, snowsheds, landslide or rock fall protection structures, and the like. More particularly, this invention pertains to an innovative use of mineral soil (clay, silt, sand, gravel, cobbles, boulders, broken rock or mixtures of any or all of the foregoing) to construct a reinforced soil arch that can be used for numerous purposes. A method of constructing a reinforced soil arch comprising constructing an arch utilizing a combination of layers of compacted mineral soil and reinforcement in a manner that supports both the dead load of the structure and a live load imposed on the structure.
