Crushed limestone is the most common base material used in my area. It has excellent stability and as BigH noted, a CBR value that usually exceeds 100. It is usually placed in thin lifts, not more than 12 inches, so bearing capacity is a bit of a misnomer. The limestone in my area is relatively impervious when compacted.

For history''s sake, ballast has its earliest beginnings as simple limestone blocks, which actually sometimes pulled double duty as both the support base and railroad track structure. In the 1840s true ballast, or crushed stone, as we know it today began to be widely used and was soon found to be far superior to the old method.

Limestone. Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Most limestone is composed of skeletal fragments of marine organisms such as coral or foraminifera. Limestone makes up about 10% of the total volume of all sedimentary rocks.

1. Introduction. Crushed limestone is increasingly being used as coarse aggregate for concrete. Unlike normal aggregates with a high composition of silica (SiO 2), limestone aggregate consists mainly of the mineral calcium carbonate (CaCO 3) that plays a significant role in the differences in the chemical and physical characteristics of concrete.. Consequently, the regulations currently
