This standard is issued under the fixed designation D ; the number 1 This test method is under the jurisdiction of ASTM Committee D18 on Soil and. Standard Test Method for Resistance R-Value and Expansion Pressure of Compacted Soils. Status: Withdrawn · Replaced by: ASTM D Buy this. Standard Test Methods. AASHTO T and ASTM D Resistance R-Value and Expansion Pressure of Compacted Soils.
The technician must also turn a crank handle that moves a displacement turns gauge on the stabilometer. Older exudation fixtures contain a circle of six contact points on the base plate. However, use of equipment manufactured to be readable in inch-pound units only should not be considered as non-conformance to the test method.
Many stabilometers and expansion pressure devices are manufactured to be readable in inch-pound units only. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

Instron assisted a steel manufacturer with a testing system and model SF split furnace to perform tensile tests to a specimen at a high temperature. Subscribe to Our Newsletters. Newer exudation fixtures contain an additional solid ring on the base plate and a corresponding light on the indicator box.

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. To follow ASTM E8, specific dimensions and gripping solutions need d22844 be used in tension testing of metallic materials like sheets, wires, and pipes.
This standard is also available to be included in Standards Subscriptions. The purpose of the test is d28444 determine the suitability of the material for use under paved roads and airway surfaces.

Glossary of Materials Testing Terms. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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.
With temperature tension tests of metals to calculate tensile strength, yield strength, and elongation or reduction, follow ASTM E21 d22844 meet modern requirements. As the voice of the U.

The R-value calculation result was automatically generated from the variables input by the user and the load values are recorded by the Partner software. When contacted by water, these points will switch-on a light on the indicator box pictured at right.
Subscribe to Instron News! The Partner Gentest application package allowed for proper test d28444, and automatically prompted the operator when to take stabilometer readings – eliminating the need for a 2nd operator.
Link to Active This link will always route to the dd2844 Active version of the standard. This test method covers the procedure for testing both treated and untreated laboratory compacted soils or aggregates astn the stabilometer and expansion pressure devices to obtain results indicative of performance when placed in the base, subbase, or subgrade of a road subjected to traffic.
The large test space and special table extension permitted the stabilometer to move easily in and out of the test space. 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.
