ASTM D6913

Particle-Size Distribution (Gradation) of Soils Using Sieve Analysis

Applicability: ASTM D6913 is applicable for determining the particle-size distribution (gradation) of soils using sieve analysis for particles between the 3-inch (75-mm) and No. 200 (75-µm) sieves. This method is crucial in geotechnical and construction engineering applications.

Purpose: The purpose of ASTM D6913 is to provide standard methods for determining the particle-size distribution (gradation) of soils using sieve analysis, helping engineers classify soils, design earthworks (like dams, roads), select fill materials, and understand engineering properties like compaction, strength, and drainage characteristics, by separating and weighing particles through a series of sieves.
