Asphalt Aggregate Gradation and Size Testing with Industrial Scales. This means the gradation of the particles is arranged in such a way that successively smaller sized particles will be packed within the spaces between larger particles. When it comes to practical application however, maximum density is not desirable because there is a certain volume of void space required for the asphalt binder....
Aggregate
An aggregate's particle size distribution, or gradation, is one of its most influential characteristics. In HMA, gradation helps determine almost every important property including stiffness, stability, durability, permeability, workability, fatigue resistance, frictional resistance and resistance to moisture damage (Roberts et al., 1996)....

WHAT IS THE IMPORTANCE OF AGGREGATE GRADATION IN .
The most efficient way to achieve workable of concrete is by adopting a good gradation of aggregate. Also aggregate comprises 85% of the volume of concrete. So we can definitely say that, most of the requirement of concrete in its plastic state is affected by aggregate properties and, "gradation of aggregate" is one of them....
