12-9-2005First, there's really no difference in this context between stone and gravel and aggregate. In C 33 there's a chart showing the grading requirements for different sizes of coarse aggregate from #1 to #8. For example, #1 aggregate is nominal size 3 to l inches (90 to 37.5 mm).
Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials. This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.
Abstract The importance of the particle size distribution (grading) of a gravel material for unsealed roads has long been recognized. Various parameters have been devised to allow interpretation of grading curves in terms of a single parameter for ease of application, control and comparison.

Crushed Gravel Sand– it is the fine aggregate produced by crushing natural gravel. According to size the fine aggregate may be described as coarse sand, medium sand and fine sand. IS specifications classify the fine aggregate into four types according to its grading as fine aggregate of grading Zone-1 to grading Zone-4.
gravel will often be blamed on the maintenance operator. But the operator cannot make good gravel out of bad gravel. Bad or poorly graded gravel can not be changed to good gravel without additional costs, but it is often well worth it. One common practice of improving surface gravel is to add new, clean, fine gravel. Good surface gravel

On Aggregate Grading is good concrete performance dependent on meeting grading limits? Specifying concrete mixtures with well-graded (WG) combined aggregates can be controversial. Advocates1-4 argue that such mixtures have optimized packing and minimal voids and therefore minimize the cementitious paste required for a given workability.
