Definition

Tests performed on granular material such as sand, gravel, or crushed stone to determine their composition, characteristics, properties, and suitability for specific uses.

Context

Natural and crushed stone aggregate serves a wide list of needs and uses around the world (Bobrowsky 1998). Most aggregate is for construction purposes, and of this, most is used in Portland-cement concrete and bituminous mixes. Specific uses require specific requirements and attributes for the materials in use. Cement aggregate needs are more rigid and less flexible than, for instance, bituminous needs. To ensure the most appropriate aggregate is used for a specific need, a suite of tests are available to assess the composition, characteristics, properties, and suitability of the aggregate materials. The most common tests include:
  • Abrasion test – determines the hardness properties of aggregate, most commonly relies on the Los Angeles abrasion test to establish the percentage of wear resulting...
