Explanation: After the impact test is conducted, the results are obtained in percentage. The aggregate is said to be exceptionally tough when the value is 10%, very tough when the value is in between 10 - 20%, good for pavement surface when the value is in between 20 – 30% and weak if the value is >35%.
