Determination of Aggregate Impact Value
The purpose of conducting an Impact Test on Aggregates is twofold. Firstly, it is performed to determine the impact value of road aggregates. This value is a measure of the strength or toughness of the aggregates and is calculated by subjecting them to a standard amount of impact. The impact value is then used to… /determination-of-aggregate-impact …
