2023年3月15日 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 bound macadam: 40

Report the mean as the aggregate crushing value, unless the individual results differ by more than 0.07 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number, and report the median as the aggregate crushing value.
