Applications Requirement

For successful product installation the following soil surveys are essential:

  • A sieve analysis to determine fine soil particles under 0.002mm.
  • Proctor test - to determine the ideal moisture for compaction.
  • Plate loading tests - to test bearing capacity prior to adding cover and during final compaction.

ANALYSIS AND LABORATORY TESTING

An in-depth study of the soil to be treated based on design requirements is a fundamental part of the nanoSOIL stabilizer process prior to treating any road project.

Various basic tests are required to support jobsite efficiency and cost effectiveness. Various soil specimens must be obtained from the road project and tested at a soil laboratory. The information obtained from the monitory tests is as follows;

  • Natural and Optimum Moisture Content (Proctor).
  • Grain size analysis and soil classification (USCS).
  • Density and compression strength (load bearing capacity - test).
  • Performance with nanoSOIL stabilizers (Capillary rise).

Grain Size Distribution Analysis

Currently there are two widely used procedures to conduct the soil grain size analysis. These are: sieved by mesh and soil suspension with hydrometer.

The purpose of the mechanical test or grain size distribution test is to determine the size of particles or grains that make up a soil and fix, in a percentage of its total weight, the amount of differently-sized grains it contains.

The second method is used for soils less than 0.063 mm requiring the moisture process, based on the Stokes' Law.

HORIBA's LA-300 Laser Diffraction Particle Size Distribution Analyzer is the ideal combination of performance, price, and packaging. Based on the advanced optical design of previous LA-series analyzers, the LA-300 strikes a harmonious balance between high-functionality, easy operation, low maintenance, and cost-effectiveness. The optimized design allows for a compact optical bench, resulting in an efficient use of bench space, while preserving the accuracy, precision and resolution that HORIBA's analyzers are famous for.

Key Features Include:

Range: 0.1 - 600µm Matching the widest range of applications with a performance equivalent to most competitors' full range systems.

Compact Size: The compact size and low weight make this a convenient analyzer for today's crowded laboratories. It also makes it possible to transport easily to different locations within a facility or ship to remote locations for on-site testing where it is not practical to purchase an analyzer.

Fast Analysis: The highly-refined optical design and algorithm provides measurement results in 20 seconds, with class-leading accuracy and precision.

Powerful Software: The LA-300 uses the same fully featured software package as our other LA-series analyzers, providing a wide range of statistical measures, data analysis, and presentation tools.

Ease of Use: With automatic alignment, built-in ultrasonic system for sample dispersion, and powerful pumping system, combined with the automation features of the software, sample analysis on the LA-300 is extremely easy and straightforward. Combined with the automation options, sample analysis can be a one-button operation.

The best composition for nanoSOIL stabilization is:

  • 1/3 clay (<0,002mm) and silt ( 0,002 – 0,063 mm).
  • 1/3 sand (0,063 – 2 mm).
  • Density and compression strength (load bearing capacity - test).
  • Performance with nanoSOIL stabilizers (Capillary rise).

Note:a minimum of 15 % - 25 % of clay (0,002mm) must be present in the soil
