Pavement materials: Aggregates

Overview. RYAN Aggregate is a collective term for the mineral materials such as sand, gravel, and crushed stone that are used with a binding medium (such as water, bitumen, Portland cement, lime, etc.) to form compound materials (such as bituminous concrete and Portland cement concrete). By volume, aggregate generally accounts for 92 to 96

Evaluation of steel slag and crushed limestone

2013-3-1  The major difference between the steel slag and crushed limestone aggregate is the bulk specific gravity. The bulk specific gravity of the steel slag aggregates is 3.34 while it is 2.4 for the crushed limestone aggregates. The water absorption of the steel slag aggregates is almost one-fourth of that of the crushed limestone aggregates.
