Enterprise Suite Version 4
Complete Suite of Geotechnical Test Programs

Both sieve and hydrometer tests are supported.

• 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 (C_c and C_u) 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 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

• 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
• Oversize correction supports the coarse/fine mass ratio oversize percentage determination per D4718
• 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

• CBR test standards: ASTM D1883 • AASHTO T 193 • Virginia Test Method 8
• User-adjustable linearity correction
• Swell data is supported but not required
• Optionally, the program will interpolate data to determine the CBR at 95% maximum dry density
• The test report presents the load-penetration curve and the test results for up to three specimens
• The report may also include swell-time graphs and CBR vs. percent compaction graphs
• CBR can import data acquisition files created by the DGSI (Durham Geo) automated load frame, and can also be configured to import data acquisition files created by customized data acquisition systems

• ASTM D2844, AASHTO T 109 and California Test 301 (CT-301) support
• Enter either exudation load or exudation pressure
• Interactive modification of the R-value vs. expansion pressure and exudation vs. expansion pressure curves

• Both Imperial and metric units are supported; data may be entered in one system and automatically converted to the other for reporting.
• Calculates UU, CU, CU with pore pressures, and CD triaxial tests.
• 3 triaxial test report formats
• Interactively adjust the strength tangent envelope
• Plot pore pressure versus strain and the stress path diagram for triaxial tests
• Calculates moisture, density, saturation and void ratio for initial, saturated, and consolidated phases
• Staged load ring constants are permitted, as well as separate constants for each specimen
• Direct shear and triaxial tests may have up to four specimens
• Four separate unconfined tests may be combined in a single report
• A data and results summary may be printed for each specimen
• Units of measure supported are cm, inches, lbs, gms, kN, psf, psi, ksf, tsf, ksi, kPa, and mPa
• Click here to view a set of datafiles used to test SHEAR's calculations. (The calculations documented in these files can help you in manually verifying the program's correctness.)
• Testing data can be imported from files created by a number of different data acquisition systems

• Swell/consolidation standards: ASTM D2435 • ASTM D4536
• Real-time adjustment of both time-rate (C_v) and compression curve (P_p and C_c) construction lines
• Supports US and SI units, automatically converting as needed
• Supports water-added (swell) tests
• Unlimited number of unload/reload cycles
• User-created deflection database allows the software to accommodate for loading frame deflection
• Imports files created by software from most common data acquisition manufacturers
• The software features both submittal-quality compression and time-rate chart reports and textural reports listing raw testing data.
• Multiple time-rate and compression curve report chart report formats are available. (Click here for .PDF samples.)

• Proctor test results are automatically available while entering field density data.
• Choose from a variety of supplied report formats.
• Can automatically add specifications to each test entered.
• Setup options for US or metric units, fonts, table sizes, etc.
• Sort and find options.
• Several convenient ways to select tests to be reported.
• Can print envelopes or mailing labels along with the report.
