Proctor Compaction Test: A Basic Guide

The saturation curve, or zero air voids curve, is a plot of soil density vs moisture at a theoretical saturation level (zero air voids). Points for plotting the curve are calculated from compacted dry unit weights of the sample material adjusted to moisture contents at saturation, using this formula stated in the ASTM D698 standard test method, among others:

What is the California Bearing Ratio (CBR)?

The basic CBR test involves applying load to a small penetration piston at a rate of 1.3 mm (0.05″) per minute and recording the total load at penetrations ranging from 0.64 mm (0.025 in.) up to 7.62 mm (0.300 in.).

The California Bearing Ratio Test (CBR) And How It Works

First, engineers collect three to five soil samples. CBR testing works best on particles less than 0.75 inches wide, so loose soil is great for this test. Its finer particles deliver more consistent results because the testing equipment contacts more of the soil's surface area. 2. Prepare the …
