18. HITEC Evaluation
What DOT can take from the report:
- Evidence of conformance w/ AASHTO methodologies
- Rigorous technical review
- Viable alternative to traditional retaining systems
28. Trial Wedge Method
Well established methodology
to resolve complex loading
conditions & geometry
Not commonly used due to
computational effort
More accurate assessment of
actual load applied outside of
Coulomb contributory area
Variation of Coulomb
technique
Still consistent with AASHTO
and other standards
