:: Substructure Laboratory ::

  

Substructure Laboratory (Soil Mechanics Lab.)

 

  The experiments dealing with the physical and mechanical properties of the disturbed, undisturbed and remolded soil specimens and some of the in-situ tests are performed by the Substructure Laboratory.

 

  Laboratory Experiments:

  1- Water content of soils using oven and Speedy Moisture apparatus

  2- Grading (Sieve analysis)

  3- Hydrometry

  4- Liquid and Plastic limits (Atterberg’s limits)

  5- Sand equivalent

  6- Compaction characteristics of soils (Standard effort)

  7- Compaction characteristics of soils (Modified effort)

  8- In-place density using sand bottles

  9- Relative density of cohesionless soils

  10- California bearing ratio (CBR)

  11- Unconfined uniaxial strength

  12- Direct shear strength

  13- Consolidation

  14- Triaxial test

  15- Permeability (Constant head)

 

  In-situ Tests:

  The in-situ tests that can be performed by the lab are as follows:

  1- Plate Loading Test

  2- In-situ CBR

  3- Stamdard Penetration Test (SPT) for clayey and granular soils
