Aggregates play a crucial role in the construction of pavements, comprising a majority of the composition in materials like bituminous and Portland cement concrete. Their specific properties, such as strength, hardness, toughness, and shape, significantly affect pavement durability and performance. Various tests are essential to evaluate these properties and ensure that aggregates meet the necessary standards for construction use.
Aggregates constitute a major part of pavement materials, impacting strength and durability significantly.
The desirable properties of aggregates include strength, hardness, toughness, shape, adhesion, durability, and freedom from deleterious particles.
Focused testing of aggregates, such as crushing, abrasion, and impact tests, is vital to ensure suitability for pavement construction.
A term for mineral materials like sand, gravel, and crushed stone used with binding agents to form materials for pavement.
The ability of aggregates to withstand compressive stress without failure, crucial for high-quality pavement.
The capacity of aggregates to resist weathering actions and other environmental factors over time.
Refers to the physical form of aggregate particles (rounded, angular, flaky, elongated) which influences their strength and stability.
The ability of bitumen to adhere to aggregates, affected by moisture and surface conditions.
