Standard Test Method for Resistance R-Value and Expansion Pressure of Compacted Soils
During the test, the operator must record horizontal pressure readings from the gauge on the stabilometer at specified compressive loads – this often requires 2 operators. When contacted by water, these points will switch-on a light on the indicator box pictured at right. You may delete a document from your Alert Profile at any time.
