Crushed Stone | Indiana Geological & Water Survey

Our modern world requires immense amounts of raw materials. Most of those raw materials must be grown or mined from the Earth. Rocks were one of the earliest tools used by man and we still use crushed stone to build and operate modern society. Per person use of geological raw materials is shown in Figure 1. In Indiana, there is enough stone used to average 8,343 lbs. per person per year.

Reading: Mechanical Weathering | Geology

Ice in glaciers carries many bits and pieces of rock. Rocks embedded at the bottom of the glacier scrape against the rocks below. Abrasion makes rocks with sharp or jagged edges smooth and round.

Nile River | Geology Page

The source of the Nile is sometimes considered to be Lake Victoria, but the lake has feeder rivers of considerable size. The Kagera River, which flows into Lake Victoria near the Tanzanian town of Bukoba, is the longest feeder, although sources do not agree on which is the longest tributary of the Kagera and hence the most distant source of the Nile itself.

These are sedimentary rocks covering large parts of the globe. These form the most commonly used type of road aggregates. Many varieties are known to exist and almost all of them are generally found suitable as roadstones. The crushing strength of sandstones varies from 600 kg/cm 2 for calcareous varieties to as much as 2500 kg/cm 2 for quartzitic types. Quartzites are widely used as roadstones because of their very hard nature, high crushing
