Standard Method of Test for Specific Gravity and Absorption of Coarse Aggregate AASHTO Designation:T 85-211 Technically Revised:2021 Editorially Revised:2021 Technical Submittee:1c Aggregates ASTM Designation:C127-12 AASHIO American Association of State Highway and Transportation Officials 555 12th Street NW Suite 1000 Washington D.C.20004 Standard Method of Test for Specific Gravity and Absorption of Coarse Aggregate AASHTO Designation:T 85-211 AASHIO Technically Revised:2021 Editorially Revised:2021 Technical Submittee:1c Aggregates ASTM Designation:C127-12 1. SCOPE 1.1. This method covers the determination of specific gravity and absorption of coarse aggregate. The specific gravity may be expressed as bulk specific gravity bulk specific gravity (saturated surface-dry (SSD)) or apparent specific gravity.The bulk specific gravity (SSD)and absorption are based on aggregate after 15-19 h of soaking in water.This method is not intended to be used with lightweight aggregates. 1.2. The values stated in SI units are to be regarded as the standard. 1.3. This standard may involve hazardous materials operations and equipment.This standard does not purport to address all of the safety concerns associated with its use.It is the responsibility of the user of this procedure to consult and establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to its use. 1.4. The quality of the results produced by this standard are dependent on the petence of the personnel performing the procedure and the capability calibration and maintenance of the equipment used.Agencies that meet the criteria of R 18 are generally considered capable of petent and objective testing/sampling/inspection/etc.Users of this standard are cautioned that pliance with R 18 alone does not pletely assure reliable results.Reliable results depend on many factors;following the suggestions of R 18 or some similar acceptable guideline provides a...
