Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA. What Is Abrasion Value Test? Abrasion Test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration.

The crushing value of good quality aggregate to be used in surface course must not more than 30% aggregate loss. The objective of the test was to determine the mechanical strength of the aggregate together with the aggregate crushing value. This experiment was based on the SSRW in Malaysia [12], on par with the British

Conclusion From the experiment, we get 6.02% where it still not exceeding JKR's standard, <30%. So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate are mild tough to have the resistance pressure under traffic wheel loads such as car, lorry, motorcycle and etc.
