At this point, the load is recorded. This test requires that the sample be compressed until either five of the six lights are illuminated or three lights and the ring light are illuminated.

ASTM D2844; AASHTO T190; CTM 301: Moisture Exudation Test Compacted Soils
The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.
The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.
ASTM D2844/D2844M – 13
The technician must also turn a crank handle that moves a displacement turns gauge on the stabilometer. This test requires a compression testing machine and a special exudation aastm pictured below. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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.
It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. In addition, they are representative of the significant digits that generally should be retained.

ASTM D Resistance R-Value Compacted Soils Stabilometer – Instron
Older exudation fixtures contain a circle of six contact points on the base plate. The test procedure requires loading the sample in compression while inside the stabilometer. Software for Series Systems. You may delete a document from your Alert Profile at any time.
To follow ASTM E8, specific dimensions and gripping solutions need to be used in tension testing of metallic materials like sheets, wires, and pipes. The turns gauge value is recorded for use in the calculation of the R-value.

The compression tester must allow for the entire stabilometer device and following ram to fit inside the compression test space. WaveMatrix 2 for Dynamic Testing.
