Determination Of Shape Tests On Aggregate
determination of flakiness index test.
Dec 18, 2017 · While elongation index test is used to determine the quantity of aggregate particles that are elongated instead of cubicle in shape. In this experiment, flakiness index was used as independent variables and other properties such as gradation are kept constant as far as their properties met the specifiion required for the asphalt mixture.
