The performed laboratory tests were the Aggregate Impact Value AIV, and Aggregate Crushed Value ACV. The results were shown in the Table 2. Standard Specification of Road Work SSRW in Malaysia 12 were used to define the mix gradation limits as shown in Table 3.
The aggregate impact value is the proportion of the sample that passes a 2.36 mm sieve after the hammer impacts. European Standards will not contain the 10 per cent fines test or the aggregate impact value test although a different impact test, the German Schlagversuch test, has been included.
coarse aggregates, the variation of aggregate crushing value of different coarse aggregates, strength gain of concrete with time for different coarse aggregates and to establish a relation between aggregate crushing value of coarse aggregate and compressive strength of concrete. In the study, Portland Composite Cement PCC has not been used.

The aggregate impact values AIV obtained from samples can be considered as significant in determining the strength of the aggregate under repeated or continuous impact. According to Dhir et al. 1971, a numerically lower result indicates a higher resistance of the aggregate during the test. It is apparent from Table 1 that Johor granite has the
Hence, they can be acceptable as their Aggregate Impact value is less than 30. Aggregate ImpactValues, AIVs, below 10 are regarded as strong, and AIVs above 35 would normally be regarded as too weak for use in road surfaces. If the aggregates are weak, the stability of the pavement structure is likely to be adversely affected.
