Abstract:
A system and method are provided for increasing the width of an existing roadway. The system incorporates a reverse-oriented retaining wall and soil nail supports. The retaining wall is formed by a first set of soil nails, wire mesh material, and one or more geotextile material layers. An alternate embodiment forms the retaining wall with a plurality of concrete blocks stacked and spaced to form a block wall. The blocks are mounted over the first set of nails and can be filled with mortar. Backfill material fills a gap between the existing sloping surface and the retaining wall. A second set of soil nails can be provided for additional subsurface support. An upper surface of the backfill material can be paved to form the extended roadway width. The cantilevered configuration of the reverse-oriented retaining wall provides a solution for a less costly retaining wall structure. This reverse-oriented retaining wall is also easier to install than traditional vertical retaining walls that may have to be installed at greater vertical and lateral distances from the existing roadway.
