Impact of Aggregate Gradation on Base Material Performance

with a focus on the gradation and especially the percentage of fines (aggregate passing the No. 200 sieve). Two materials were obtained from two local quarries for this purpose. The percentage of fines was varied in these mixtures. Each mixture was then put through a regime of tests to determine the effects that the gradation and

What are the grades of coarse aggregate? Quora

Gradation of coarse aggregate - Well graded Well-graded aggregate has a gradation of particle size that fairly evenly spans the size from the finest to the coarsest. A slice of a core of well-graded aggregate concrete shows a packed field of many different particle sizes.
