Decomposed Granite Gravel (DGG) is the ultimate for driveways and pathways. Mined in the Texas Hill Country, this material has small, coarse granite chunks and lots of fine material. When installed as a driveway or pathway, the fine material takes a hard set, while the coarser material rises to the surface.

Crushed stone, including crushed granite, is a material much easier to handle and place, and is commonly known as gravel. These small shards of stone have endless applications in the garden, not the least of which involve the base and the top layer for a driveway.
3.3 Coarse aggregate . Machine crushed blue granite broken stone angular in shape is used as coarse aggragate. The coarse aggregate is choosen by shape as per IS 2386 (Part I) 1963, surface texture characteritics of aggregate is classified as in IS 383 - 1970. The following properties of coarse aggragates were determined and tabulated in Table3.3

Coarse aggregate of 20mm maximum size is used in Reinforced cement concrete work of all types of structures. This is obtained by crushing the stone boulders of size 100 to 150mm in the stone crushers. Then it is sieved and the particles passing through 20 mm and retained on 10mm sieve known as course aggregate.
The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ-ence the concrete's freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed stone with most particles smaller than 5 mm (0.2 in.).
