Mainly used as a foundation. 3. Crushed Stone #57 Gravel. Usually, crushed stone #57 is used as the middle layer of a gravel driveway. It typically consists of golf-ball-sized crushed stone, hence the name. It is made from machine-crushed rock and is often used in many different sorts of landscaping projects.

GraniteCrete is a portland-cement-based aggregate binder used with locally sourced, ground, decomposed granite or other suitable aggregate to produce porous, natural-looking walkways and other low-traffic pavement. I first came across the product at last year's West Coast Green conference in San Francisco and have been wanting to dig …

The second layer is intended to provide drainage, so it typically consists of 2.5-inch to 3-inch crushed gravel that allows water to drain freely through the aggregate. Finally, the top layer should be made up of a functional and decorative style of crushed gravel, like decomposed granite or pea gravel.

In Lithuania, granite aggregates are often used for asphalt wearing layer, but this magmatic rock is imported from other countries. Dolomite is one of the most available sedimentary rocks in Lithuania and quarries contain hundreds million tons of this material. These aggregates are often used for asphalt binder layer, base and base-wearing layers.

A mixture of granite aggregates 0/31.5 and lateritic gravels will have low CBR values ranging from 40 to 60. Mixing 25 wt% granite aggregates 5/20 with 75 wt% lateritic gravels yields a significant increase of about 34% in the value of CBR (~82) (Table 6), making these materials suitable for use as base road layers.
