Aggregate impact value (AIV), aggregate crushing value (ACV) and ten percent fines (TFN) value are common tests used to determine aggregates strength. Aggregate abrasion value (AAV), Los Angeles abrasion value (LAAV) and polished stone value are used to test the durability of the aggregates.
The Polished Stone Value (PSV) test is an important evaluation method for the skid resistance of road surfaces. The test measures how quickly a sample of aggregate becomes polished or smooth after repeated passes of tyres. The rough texture of the road surface layer is essential for providing skid resistance to traffic.

Aggregate Crushing Value (ACV) is an index of loss of coarse aggregate (CA) under sustained loading. However, ACV is not considered in concrete mix design according to ACI 211.1(ACI 211.1, 2009). In this paper effect of ACV of CA on compressive strength of concrete has been explored. Coarse Aggregate was collected from five different …
The strength and durability of crushed rock aggregates depends on the physico-mechanical characteristics of the rock. Result of andesite aggregate from Umuchieze Lokpaukwu indicates that the aggregate possess mean aggregate crushing value (ACV) of 14.8%, mean aggregate impact value (AIV) of 12.6%, mean los Angeles abrasion value (LAAV) …

The paper aimed to collect all available relationships and datasets from the literature that presents the relations between these different parameters – such as Aggregate Impact Value (AIV), Aggregate Crushing Value (ACV), Ten Percent Fines Value (TFV), Los Angeles Abrasion Value (LAAV), and micro-Deval Coefficient (MDE) – …
Aggregate Crushing Value (ACV) – this is the measurement of the resistance of aggregate to crushing by compressive force. A test specimen (10-14mm) is compressed (up to 400 kN) and the proportion of material passing …
The specifications of the aggregate samples are kept similar for all of these three test procedures. The result indicates a strong correlation of Light compaction values (LCV) with Aggregate crushing values (ACV) and Aggregate Impact Values (AIV). The R 2 values for the relationship was found to be more than 0.9 for both these relationships.
