ASTM D5202/D5202M-16 PDF Download

The ASTM D5202/D5202M-16 standard is titled "Standard Test Method for Determining Triaxial Compression Creep Strength of Chemically Grouted Soils." This standard provides a method for determining the long-term strength and deformation of cylindrical specimens of chemically grouted soils when they are sheared undrained in compression under a constant sustained load.

The purpose of this test method is to obtain data that can be used for structural and geomechanical design purposes. It is important to note that adequate safety factors, based on engineering judgment, must be determined by the user of this standard.

The quality of the test results obtained using this method is dependent on the competence of the personnel performing the test, as well as the suitability of the equipment and facilities used. It is recommended that testing agencies meet the criteria outlined in Practice D3740, which evaluates the competence and objectivity of testing, sampling, and inspection.

The standard emphasizes the importance of proper sampling procedures for in-situ specimens, as well as careful sample preparation methods for laboratory-fabricated specimens. The test results may be influenced by the sampling and preparation techniques used.

It is also worth mentioning that this test method is not applicable to partially grouted soils in which substantial pore pressures may develop. If pore pressures need to be measured, reference should be made to Test Method D4767.

The values obtained from this test method should adhere to the guidelines for significant digits and rounding established in Practice D6026. The standard also provides instructions for performing the test, but it is important to use professional judgment and consider the unique aspects of each project. The ASTM standard does not replace the standard of care by which the adequacy of a professional service is judged.
