Soil & Gravel
SERVICE OFFERING
01
Wet Particle Size Analysis
Material classification and determining compliance to the particle size distribution of gravels.
02
Atterberg Limits
Liquid limit, plasticity index & linear shrinkage, determines the moisture required to for a liquid or plastic state.
03
Oven Drying by Constant Mass
Mitigate the effects of moisture and ensure oven dried samples attain constant mass when dried.
04
MDD and OMC
Determine maximum dry density (MDD) and optimum moisture content (OMC) of material.
05
California Bearing Ratio (CBR)
CBR is determined by penetrating a piston into material prepared in accordance to SANS 3001 GR30.
06
Laboratory Mixed Cementitious Stabilised Materials
Used to determine the maximum dry density, optimum moisture content, indirect tensile strength and more.
07
Unconfined Compressive Strength (UCS)
Can be used to determine compliance to specifications for compressive strength of stabilized gravels.
08
Indirect Tensile Strength (ITS)
Can be used to determine compliance to specifications for indirect tensile strength strength of the material.
09
Wet-dry Durability
Gives indirect indication of the durability or expected degradation of material being tested.
10
Dynamic Probe Super Heavy
Used in favourable conditions to determine the expected bearing capacity of soils .
11
Cored specimens
This method is used to extract field specimens (cores) of stabilized material for laboratory testing.
12
Sand replacement
Determines the in-situ density of a layer where the nuclear density method is unsuitable.
13
Dynamic cone penetrometer (DCP)
Used to determine the resistance of the material and interpolate the expected California Bearing Ratio.
14
Plate load test
Determine the ultimate bearing capacity of soil and the probable settlement under a given load.
