Description

Standard: BS 1377-4, 1924-2, EN 13286-2, EN 13286-47

Proctor CBR Soil Compactor, Automatic, Eco Smartz (ASTM/AASHTO) NL 5025 X / 005A

Proctor CBR Soil Compactors, Automatic

Proctor CBR (California Bearing Ratio) Soil Compactor is used for proctor compaction tests on soil samples, allowing for determining maximum dry density and optimum moisture content in geotechnical engineering according to standardized procedures. This process involves compacting soil samples in a standard mold under controlled conditions. This helps evaluate the mechanical strength of natural ground, subgrades, and base courses for pavement design, measuring the load-bearing capacity of soil when compacted to specific density and moisture content.

Newly upgraded model by using ECO-SMARTZ system for energy saving and consistency operation. Solid and compact design allows uniform and correct compaction of Proctor and CBR samples.

Proctor CBR Soil Compactor, Automatic, Eco Smartz (BS/EN)

Proctor CBR Soil Compactor, Automatic (BS/EN) is used to test soil properties in construction and geotechnical engineering. This compact unit is capable of automatically performing two key sets: the Proctor test and the California Bearing Ratio (CBR) test. The Proctor test helps determine soil compaction characteristics by assessing maximum density and optimal moisture content, while the CBR test evaluates soil strength for road construction. Automation streamlines the testing process, enhancing efficiency, accuracy, and productivity. By automating these tests, the compactor ensures consistency and reliable results, making it an invaluable tool for soil analysis in construction projects.

Test Procedure

Proctor CBR Soil Compactor, Automatic, Eco Smartz (ASTM/AASHTO) NL 5025 X / 005A

Test Procedure of Proctor CBR Soil Compactors

  1. Sample Preparation:
    • Collect representative soil samples from the site.
    • Air-dry the samples and break up any aggregates.
    • Sieve the soil to remove any large particles or debris.

  2. Determination of Moisture Content:
    • Take a portion of the prepared soil sample and determine its initial moisture content using an appropriate method, such as ASTM D558 or AASHTO T134.

  3. Compaction Test:
    • Set up the Proctor/CBR Soil Compactor according to the manufacturer’s instructions and calibrate it if necessary.
    • Place a specified amount of soil into a standard compaction mold (usually a cylindrical mold with known dimensions).
    • Determine the compaction effort required based on the type of Proctor test being conducted (Standard Proctor or Modified Proctor).
    • Compact the soil in layers by applying a specified number of blows from the compaction hammer. The blows are evenly distributed over the surface of each layer.
    • Measure and record the height of each compacted layer.
    • Repeat the compaction process for additional soil samples at varying moisture contents.

  4. Determination of Dry Density:
    • After compacting all the samples, carefully extract them from the molds.
    • Determine the dry weight of each compacted sample by oven-drying them to remove all moisture (ASTM D558 or AASHTO T134).
    • Calculate the dry density (bulk density) of each sample using the known volume of the mold and the dry weight of the soil.

  5. Plotting the Compaction Curve:
    • Plot a graph of dry density versus moisture content for the tested soil samples.
    • Identify the maximum dry density and the corresponding optimum moisture content from the curve.

  6. Interpretation:
    • Evaluate the results to determine the suitability of the soil for engineering applications, such as road construction or foundation design.
    • The maximum dry density and optimum moisture content provide crucial information for achieving the desired level of compaction in the field.

Test Procedure of Proctor CBR Soil Compactor, Automatic, Eco Smartz (BS/EN)

  1. Preparation of Soil Sample: Collect the soil sample for the testing site. Ensure the soil sample is free from any debris or foreign materials. Then, determine the required moisture content for testing based on specific standards or project requirements. 

  2. Compactor Setup: Calibrate the Eco Smartz Automatic Proctor/CBR Soil Compactor according to the manufacturer’s instructions and adjust the compactor settings such as compaction energy, compaction mode (Proctor or CBR), and test parameters (moisture content, number of blows, etc.).

  3. Compaction Test: Place a portion of the prepared soil sample into the compaction mold or Proctor/CBR mold. Set the compactor to perform the desired test (Proctor or CBR) and input the necessary parameters. Start the compaction process, allowing the machine to automatically compact the soil sample according to the specified standards. Monitor the compaction process to ensure proper compaction energy and technique are applied.

  4. Measurement & Analysis: After compaction is complete, remove the soil sample from the mold. Measure and record the dimensions and weight of the compacted soil specimen. Conduct additional tests if necessary, such as moisture content determination for Proctor tests or soaking for CBR tests. Analyze the results obtained from the compaction test, including the maximum dry density, optimum moisture content, and any other relevant parameters.

  5. Data Reporting: Document all parameters, procedures, and results in a test report and ensure all report complies with relevant standards and project specifications. Do provide conclusion and recommendations based on test results, if required. 

  6. Equipment Maintenance: Make sure to clean and maintain the Eco Smartz Automatic Proctor/CBR Soil Compactor according to the manufacturer’s recommendations to ensure continued accuracy and performance.
