2020-1-20  Wu et al. proposed that the aggregate used for OGFC should meet the standard of SMA, and the crushing value of coarse aggregates should not be more than 24% . Guo believed that the skeleton-void structure formed in the PA mixture reduced the contact area between the aggregates by about 25% compared with the ordinary dense graded asphalt mixture, resulting in an increase in stress magnitude between the contacting aggregates.

2021-7-7  Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100. Lab Report
