The aggregate impact value (AIV)

Formula for aggregate impact value : AIV = M2 X100%
M1

6.0 DISCUSSION :

* Interpret and comment the results obtained
a. Give the good value for the AIV test in highway engineering. Compare the standard

result and your experiments result of AIV value.
b. Give two experiments for aggregate degradation other than AIV test.
c. State the permissible value of AIV required by JKR and explain what would have
happened if the specified value is not met.

7.0 CONCLUSION
*Give your conclusion from this experimental and explain the result you get.

8.0 REFERENCES:
*Give at least 5 references you refer
