County of Orange Public Works – La Pata Gap Closure

GMU worked on the geotechnical investigation and design of the County’s La Pata Gap Closure project intermittently since the initial feasibility studies in 2003. GMU’s investigation and design services address large-scale landslides, complex slope stability analysis, extensive grading, deep fill settlement, bridge foundation design, and pavement design. Pavement engineering services involved asphalt coring and sampling, laboratory testing, and engineering analysis. The pavement design incorporated the use of warm mix asphalt, rubberized asphalt, and pavement interlayer mat for asphalt overlay.
