Grading of an aggregate is determined by sieve analysis. Maximum size and grading are invariably controlled by specifications that prescribe the distribution of particle sizes to be used for a particular aggregate material for asphalt mixtures. The distribution of the particle sizes determines the stability and density of the asphalt mixture.

2020-4-29The particle size distribution of artificial sand rolled by rod mill has a certain rule, that is, one kind of fineness modulus has only one kind of particle size gradation. Therefore, in the production of artificial sand, it is necessary to control the stability of fineness modulus, and the grading of its particle size does not need to be ...

Particle-size Distribution. Particle-size distribution is important for various uses of aggregate. Aggregate is classified into two general sizes coarse grained and fine grained. Coarse aggregate is rock retained on a 38-inch 4 U.S. sieve. Fine aggregates pass the 38-inch sieve and are retained on a 200 U.S. sieve. 6. Fine Aggregate

2015-4-27of the fine aggregate has a more significant impact on water demand than the shape of the coarse aggregate. Further, within the permit-ted standard limits, the particle size distribution of the fine aggregate was found to have a greater influence in the properties of concrete than that of the coarse aggregate. As a result, the choice of the ...
