Earth Excavation Checklist The following checklist should be used as a guide for better quality control over earth excavation. (1) Prior to the start of excavation operations, take
Shear Strength Test of Soil The choice of appropriate shear strength tests for a particular project depends on the soil type, whether the parameters will be used in
Types of Soil Shear Test Based on Drainage Condition The shear strength parameters in the case of saturated soils depend very much upon the drainage conditions and therefore
Measurement of Soil Compaction in the Field It is necessary in many instances to know the wet/dry densities of the soil in the field, especially before planning activities
Determination of Organic Matter in Soil Purpose: This test is performed to determine the organic content of soils. The organic content is the ratio, expressed as a percentage,
Relative Density or Density Index Test of Sand Purpose: This lab is performed to determine the relative density of cohesionless, free-draining soils using a vibrating table. The relative
Density Test of Soil Purpose: This lab is performed to determine the in-place density of undisturbed soil obtained by pushing or drilling a thin-walled cylinder. The bulk density
How to Classify Soil Visually on site? Purpose: Visually classify the soils. Standard Reference: ASTM D 2488 – Standard Practice for Description and Identification of Soils (Visual –
Unconfined Compressive Strength Test of Soil Purpose The primary purpose of this test is to determine the unconfined compressive strength, which is then used to calculate the unconsolidated
Standard Penetration Test (SPT) Procedure Aim To perform standard penetration to obtain the penetration resistance (N-value) along the depth at a given site. Equipment & Apparatus Tripod (to
