One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS:2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.

· If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.

aggregate crushing value (ACV) and ten percent fines value (TFV) tests were also done using BS 812: Part 110 [30] and BS 812: Part 111 [31] correspondingly. Lastly, EN 1097-2 [32] was used for the aggregate impact value (AIV) test. Results and Discussion Geology of study area
