Proctor test

• The standard Proctor, generally used for capping layers and embankments;
• The modified Proctor, used for base layers.

Two different mold types are used in practice depending on the grading of the soil tested:

• Proctor mold;
• CBR mold.

For the Proctor test, CiviLab applies the following standards:

• ASTM D1557-91;
• ASTM D698;
• BS 1377-2:2022;
• NA 5262;
• NF P 94-093.

With our soil software "CiviLab", you can easily perform the Proctor test calculations and archive the test reports properly. CiviLab also produces high-quality reports and archives them properly

CiviLab allows you to:

• Calculate the optimum water content W_OPN, and the maximum dry density γ_OPN of the standard Proctor test;
• Calculate the optimum water content W_OPM, and the maximum dry density γ_OPM of the modified Proctor test;
• Plot the compaction curves (you can plot several curves on the same sheet);
