Practical aggregate testing procedures, calculations, quality-control guidance and Excel formats for highway, pavement, concrete and infrastructure projects.
Evaluate aggregate grading, strength, toughness, abrasion resistance, particle shape, cleanliness, specific gravity, water absorption and aggregate-bitumen adhesion characteristics as applicable to the project.
Aggregate properties directly influence pavement strength, durability, skid resistance, workability, compaction and long-term performance of highway and concrete works.
Aggregate testing helps engineers and laboratory teams verify whether a material source is suitable for the intended application. Depending on the project, testing may include grading, impact resistance, crushing resistance, abrasion resistance, particle shape, cleanliness, specific gravity, water absorption and aggregate-bitumen adhesion characteristics.
For highway QA/QC, aggregate test results should be evaluated against the applicable project specification, approved material source requirements, relevant IS provisions, MoRTH requirements and the approved ITP/QAP.

Aggregate testing helps determine grading, strength, toughness, abrasion resistance, particle shape, cleanliness, specific gravity, water absorption and other properties required for the intended pavement or concrete application.
Depending on the material and project requirements, commonly performed tests include sieve analysis, Aggregate Impact Value, Aggregate Crushing Value, Los Angeles Abrasion, flakiness and elongation, specific gravity, water absorption, cleanliness and stripping-related tests.
The Aggregate Impact Value test is used to assess the toughness of aggregate and its resistance to impact loading under the specified laboratory procedure.
AIV evaluates aggregate resistance to impact, whereas ACV evaluates resistance to crushing under gradually applied compressive load. They assess different aspects of aggregate mechanical performance.
Excessive flaky or elongated particles can adversely affect packing, compaction and pavement performance. Applicable limits should therefore be checked against the relevant project requirements.
