tailieunhanh - Standard method of test for particle size analysis of soils

Standard method of test for particle size analysis of soils describes a procedure for the quantitative determination of the distribution of particle sizes in soils. The following applies to all specified limits in this standard: For the purposes of determining conformance with these specifications, an observed value or a calculated value shall be rounded off “to the nearest unit” in the last right-hand place of figures used in expressing the limiting value, in accordance with ASTM E 29. The values stated in SI units are to be regarded as the standard. Refer to R 16 for regulatory information for chemicals.   | Copyrighted Materials Copyright 2011 AASHTO Retrieved Standard Method of Test for Particle Size Analysis of Soils AASHTO Designation T 88-10 American Association of State Highway and Transportation Officials 444 North Capitol Street .
