ElementsSystems
ElementsSystems
High Performance Materials• Polymer Asphalt• High Performance concrete• High Performance steel• Self-Consolidating Concrete• High Strength Concrete• Initial Overlays
Retaining Walls• Remove retaining walls, purchase additional
Right of Way (ROW), Lay slope back at 3:1 • Soldier Pile, Soil Nailed or Secant Walls
Service Drive Expansion• Near Wayne State University (WSU)
parking garage expand service drive over slope.
Foundations for Interchanges• Single/mono shaft• Large diameter closed in steel pipe pile• Post grouted shaft
Railway Crossings• Construct temporary railroad bridges as
necessary• Diverge rail traffic onto one bridge in areas
with multiple tracks• Roll in pre-fabricated bridge over short
closure period• Edge girder floor beam system
Interchange Construction Staging• Build new ramps before eliminating
movements• Construction Planner
• Manage sequence of construction for whole interchange
• Ramp Bridges• Segmental Box• Steel Box/Plate
• Temporary Structures to move traffic
Advanced Contracting• Identify bridges for early
construction/replacement due to poor condition• Advanced relocation of utilities
Design to Minimize Future Maintenance• Eliminating expansion joints, design for
continuity• Minimize number of bearings
Erection Methods• Self Propelled Modular Transport (SPMT) • Roll In• High capacity cranes• Erection Gantry
