Soils Testing Laboratory

Soils Testing Laboratory

Director: Andrea Welker, PhD, Professor, Department of Civil and Environmental Engineering 

Focus: Soil testing including classification of soils and evaluation of compaction, shear strength, and hydraulic conductivity.

Tests Performed:

  • Index tests
  • Relative density
  • Falling and constant head tests
  • Rigid wall hydraulic conductivity
  • Flexible wall hydraulic conductivity
  • Direct shear
  • Compaction
  • Unconfined compression

Experimental Highlights:

  • Grain size distribution (sieve and hydrometer analysis)
  • Atterberg limits
  • Water content
  • Index properties and identification of soil
  • Hydraulic conductivity
  • Design of laboratory-scale retaining walls
