This test method covers the determination of the California Bearing Ratio CBR of soil tested in place by the penetration load of the soil.
Stay on Page Continue to Compass. This test method covers the evaluation of the relative quality of subgrade soils, but is applicable to subbase and some base-course materials. Note 1-Field in-place astm d are used to determine the astm d strength of soils, subbase, and some base materials in the condition at which they exist at the time of testing.
Active Risk Management
Many civil engineering projects use soils as fill material, with soil normally being compacted to a dense state to ensure that it has the optimum properties. However, any significant treating, disturbing, handling, compaction, or water change can affect the soil strength and make the prior to test determination inapplicable, astm d to the need for retest and reanalysis.
Danaher The corporate holding company in the USA. Similarly Indexed Publications by Subject click to wstm. Work Item s – proposed revisions of this sstm. It is scientifically undesirable to combine the use of two separate sets of dd4429 units within a single standard. Link to Active This link will always route to the current Active version of the standard.
In addition they are representative of the significant digits that generally should be retained. This implicitly combines astm d separate systems of units, that is, the astm d system and the gravitational system.
CBR Field Test Set
Combining values from the two systems may result in v with the standard. Combining values from the two systems may result in non-conformance with the standard.
This test method is designed to test in-situ materials astm d corresponds to Test Method Astm d Any astm d activities, such as grading or compacting, carried out subsequent astm d the bearing ratio test will probably invalidate the results of the test. This test method covers the evaluation of the relative quality of subgrade soils, astm d is applicable to subbase and some base-course materials.
Formerly under the jurisdiction of Committee D18 on Soil and Rock, this test method was withdrawn in February in accordance with section Precise control over the level of compaction is essential to achieve best results at reasonable cost, with d442 compaction tests being used as they provide the basis for control procedures that are subsequently used on site.

It is beyond the scope of this standard to consider significant digits used in analysis methods or engineering design. Services Installation Calibration Training. This test method has been written using the gravitational system of units when dealing with the inch-pound system. No method presently exists astm d d the precision of a group of non-repetitive plate load tests on soils and flexible pavement components due to the variability of these materials.
Combining values from astm d two systems may result in non-conformance with astm d standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
This test method has been written using the astm d system of units awtm dealing with the inch-pound system. Top Categories Terms astm d Use. This test method covers the evaluation of the relative quality of subgrade soils, but is applicable to subbase Reliable testing depends on many astm d Practice D provides a means of evaluating some of those factors.
This test method is designed to test in-situ materials and corresponds to Test Method D If astm d field S is to be used astm d for evaluation or design without consideration for variation due to change in water content, the test should be conducted under one of v d following conditions: The time and effort required to prepare specimens for compaction studies and other test methods can often be costly and time-consuming.

Work Item s — proposed revisions of this standard. Such results have direct application in test section work and in some expedient construction, military, or similar operations.

However, conversions are given in the SI System. However, there are numerous ways of preparing samples and in this respect American practice differs in detail from British practice. The test requirements are wstm to astj joint assemblies prior to field installation of pipe.

It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. It is scientifically undesirable to combine the use of two separate sets astm d inch-pound units within a single standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Field in-place Astm d tests are used for astk and design of flexible pavement components such as base and subbase course and subgrades and for other applications such as unsurfaced roads for which CBR is the desired strength parameter.
In this system, the pound lbf represents a unit of force weight. 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.
