Experimental and Numerical Study on Ballast Flakiness …

The results showed that there was a 14.7% and 5.2% decrease in strength and friction angle of aggregates with 20% increase in the percentage of flaky aggregates. An aggregate limit of 25% by weight for misshapen particles is recommended to meet the minimum shear stress level of the flaky ballast sample in the Chinese standard.
