LabSuite reduces and reports the data from sieve and hydrometer, Atterberg limits and Proctor (moisture-density) tests and automatically classify soils via USCS, AASHTO, USDA, Burmister and DOT-specific methods.


  • Reports can be exported to .PDF files
  • Raw testing data can be exported to XML files which can be imported into Excel
  • The software features both submittal-quality chart reports and textural reports listing raw testing data.
  • Multiple report chart report formats are available for reporting particle size, Proctor and Atterberg test results.
  • Calculated results (e.g., percent gravel, sand, silt and clay, LL, PL and PI and USCS soil classification) are available for inclusion on LOGDRAFT boring log reports.

LabSuite is site licensed. One license fee covers unlimited installations at a single address and there are no ongoing maintenance costs.

LabSuite supports both sieve and hydrometer tests.

  • ASTM C136 • ASTM D422 • ASTM D1140 • ASTM D6913 • AASHTO T 11 • AASHTO T 27 • AASHTO T 88 • Australian Standard AS 1141.11 • State DOT StandardsASTM C136 • ASTM D422 • ASTM D1140 • AASHTO T 11 • AASHTO T 27 • AASHTO T 88 • Australian Standard AS 1141.11 • State DOT Standards
  • Sieve tests can utilize multiple sample splits
  • Conformance to specification can be reported for selected sieves
  • Specifications are stored in a program-maintained database for reuse on subsequent tests
  • A composite particle size distribution curve is built from sieve and hydrometer tests performed on a single split sample
  • Fractional percentages (e.g., percent gravel, coarse, medium and fine sand, etc.) are calculated and reported. Percentages can be calculated using the particle size divisions specified by ASTM, AASHTO, Burmister, Wentworth, CanSIS, BS 5930 and others.
  • Diameters at various retained percentages (e.g., D10, D30, D60), coefficients of concavity and uniformity (Cc and Cu) fineness modulus results are automatically calculated from the particle size distribution curve
  • Curves may be plotted on semi-log, Wentworth (Phi), .45 power, log(size) vs. probability or linearly-scaled charts
  • Charts can also include specification envelopes indicating conformance to user-entered specifications

Atterberg Limits and Soil Classification

Atterberg and Textural Triangle Report Samples
Atterberg & Textural Triangle Report Samples
  • Atterberg standards: ASTM D4318 • AASHTO T 89 • AASHTO T 90 • Australian Standard 1289.3.1.1, 1289.3.2.1 and 1289.3.3.1
  • Index values (Atterberg liquid and plastic limit, plasticity and liquidity index) are automatically calculated from raw moisture content data and blow counts
  • One-point liquid limits are supported
  • Natural moisture contents are calculated via ASTM D2216
  • Using particle size and Atterberg data the program can automatically classify soils using a number of different methods, including USCS (ASTM D 2487) AASHTO M 145 (aka ASTM D3282), USDA, Burmister and AS 1726.

    Additional DOT-specific classification systems are freely downloadable from our website/
  • USDA textural triangle reports can be generated

Proctor Test Features

  • Moisture-density test standards: ASTM D698 • ASTM D1557 • ASTM D4718 • AASHTO T 99 • AASHTO T 180 • AASHTO T 224 • California Test Method 216 • User-Defined + State DOT Standards
  • Optimum moisture and maximum dry density results are automatically calculated from the mathematically-modeled moisture vs. density curve
  • Results can be automatically corrected for the presence of oversize (rock) material
  • User-defined test specification table allows you to add support for DOT-specific blows/layers/mold diameter requirements
  • When matched with curves form multi-point tests on similar soils, moisture-density curves may be synthesized from one-point Proctor tests
  • Container weight database: The software can be set up to keep a list of IDs and weights for moisture content containers
  • Selectively omit compaction test points from the moisture-density curve
  • Moisture-density test results rounding are selectable on a per-test specification basis (e.g., ASTM D 698 requires rounding the maximum dry density and optimum moisture content to the nearest 0.1, while D 1557 requires rounding to the nearest 0.5)
  • Selectable chart scales
