This specification covers the quality and grading of the following materials for use in the construction of subbase, base, and surface courses: sand-clay mixtures; gravel; stone or slag screenings; sand; crusher-run coarse aggregate consisting of gravel, crushed stone, or slag combined with soil mortar; or any combination of these materials. The requirements are intended to cover materials having normal specific gravity, absorption, and gradation characteristics. Where other materials are to be used, appropriate limits suitable to their use must be specified. The material shall be classified into two types namely Type I and Type II. Type I mixtures shall consist of stone, gravel, or slag with natural or crushed sand and fine mineral particles passing a No. 200 sieve and shall conform to the requirements specified for Gradation A, B, C, or D. On the other hand, Type II mixtures shall consist of natural or crushed sand with fine mineral particles passing a No. 200 sieve, with or without stone, gravel, or slag, and shall conform to the requirements specified for Gradation E or F. Different tests shall be conducted in order to determine the following properties of the aggregates: abrasion loss, liquid limit, plastic limit, and plasticity index.
