wide range of particle sizes and a substantial amount of the intermediate particle sizes. Poorly graded is defined as a soil that consists predominately of one particle size (uniformly graded), or has a wide range of particle sizes with some sizes obviously missing (gap graded). Once the grading determination has been made, the classification
Particle size distribution analysis of coarse aggregate . An attempt at applying the digital image processing DIP technique to analyze the particle size distribution of coarse aggregate is made Three different types of aggregates have been analyzed and their grading curves are compared to those obtained by conventional mechanical sieving

Finepowdered stone sludge was mixed with waste silt of larger particle size; vibratory compaction was applied for good water permeability, resulting in a smaller amount of solidifying agent being used. ... 36. 755e760.. the ...
Field testing and statistical analysis are used to study the physical and compaction properties of granular materials with artificial grading behind the particle size distributions. The statistical properties in PSD of dam granular materials and how the variation of PSD renders statistical constant are revealed.

Dec 24, 2016· QUALITY OF AGGREGATE FOR ASPHALT CONCRETE. ... Blast furnace slag is the most commonly used artificial aggregate or lightweight aggregate. ... SIZE AND GRADING. The maximum size of an aggregate designates the smallest sieve size through which 100 percent of the material will pass. Grading of an aggregate is determined by sieve analysis.
The particlesize distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size.
