Aggregates for Concrete
Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.

Calcined bauxite above 75# (C/M ≥ 1) satisfies the requirements of polishing resistance, abrasion resistance, and crushing resistance, so could be used in the ultra-thin friction course. Compared with basalt, 80# calcined bauxite (C/M ≥ 3) has better long-term skid resistance, even though the pavement surface is subject to heavier traffic.

Basalt Rock Properties and Uses
Basalt is a finely granulated igneous rock, which is usually black or gray in color. Most basalt rocks are primarily composed of the minerals pyroxene and feldspar. These rocks are formed due to lava flow. It is a type of rock that is abundantly found in the crust of the Earth, and although now found very commonly on land, most ocean floor ...
