Aggregate Impact Value Test

Aggregate Impact Value Test
The Aggregate Impact Value (AIV) Test is an important method for determining the toughness and stress resistance of coarse aggregates, assuring their suitability for high-performance applications in roadways and structural layers. This test, which follows standards such as BS 812-112 and ASTM D5874, determines how aggregates respond to abrupt loading by imitating circumstances found in automotive traffic or seismic activity. The findings are critical for selecting materials for pavement layers, particularly for surfaces that are subjected to dynamic or severe repetition loads. The AIV test helps to improve the long-term performance and safety of highways and structures by detecting aggregates that may fracture under stress, lowering the risk of early failure.

Advantages of Aggregate Impact Value Test:

• Evaluates aggregate toughness under impact stresses.
• Aids in the selection of long-lasting materials for road surfaces.
• Conforms to ASTM and BS standards.
• Prevents premature pavement deterioration.
• Ideal for both new construction and renovation.
