In the present study, some of the industrial waste aggregates viz., Blast furnace slag (BFS), Quarry waste (Q-Waste), Marble waste (M−Waste), and Overburden sand (OB-Sand) are selected for evaluation of their crushing characteristics.
The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing …
This ratio is known as the Aggregate Crushing Value (ACV) and can be calculated using the following formula: Aggregate Crushing Value (ACV) = (W2 x 100) / (W1 - W) Example limits. Here is a list of the Aggregate Crushing Value limits for different types of road construction: Types of Roads / Pavements: Flexible Pavements. Water …
The aggregate crushing value is obtained by the following expression: Aggregate crushing value = (frac{W1}{W2} times 100) W2 = Total weight of the dry sample. W1 = Weight of material passing 2.36 mm I.S. sieve. Additional Information The aggregate crushing value should not be greater than 30% for the surface course and …
