In general, 40mm size aggregate used for normal strengths, and 20mm size is used for high strength concrete. the size range of various coarse aggregates given below. Coarse aggregate: Size: Fine gravel. 4mm – 8mm. Medium gravel. 8mm – 16mm. Coarse gravel. 16mm – 64mm. Cobbles. 64mm – 256mm.
Well-graded gradations allow particles to pack together tightly with minimal voids remaining after compaction. This results in high densities. Gap-graded and uniformly-sized aggregates cannot compact to the same density due to unfilled space between particles. Higher aggregate density translates to improved strength.

Density of aggregate in kg/m3. Density of aggregate is a critical factor in the construction industry as it plays a significant role in determining the strength, durability, and overall quality of a structure. It is a fundamental physical property of aggregates that refers to the mass per unit volume of materials.

Coarse Aggregate: Fine Aggregate: 1. The size of coarse aggregate ranges from 4.75 mm to 20 mm: The size of fine aggregate ranges from 75 microns to 4.75 mm: 2. The shape of coarse aggregates is found mostly in flaky, elongated, Angular, or rounded: It Provides strength and stability to the concrete: 3.
Aggregate is usually described as either coarse aggregate (retained 4.75 mm) or fine aggregate (passing 4.75 mm). Aggregates generally make up about 95 percent of the total mass of hot-mix asphalt mixtures and 80 percent by mass of concrete - aggregate properties are, therefore, critical for quality hot-mix asphalt or concrete.

Other classifications of aggregates may be based on bulk density, (previously termed "unit weight") (ASTM C 33, C 330, and C 637), mineralogical composition (ASTM C 294), and particle shape, but these, as well as the ones previously discussed, serve mainly as aids in describing an aggregate.
20mm aggregate would need a depth of at least 40-50mm, and at least 50-60mm on driveways. Please note: The aggregate calculator's calculated tonnage is approximate. The exact conversion will depend on a few other factors, such as the bulk density of aggregate, the method and degree of compaction, and more.
