dc.description.abstractQuality controlling of aggregates is a major concern in aggregate industry. Cost of quality controlling can be minimized via finding correlations between different test on aggregates and rocks. Los Angeles abrasion value test, Aggregate impact value test, Uni-axial compressive strength test, Point load index and Schmidt hammer rebound value test were performed on a total of 22 gneissic metamorphic rock samples, which were collected from selected two quarries in Meepe and Nebada areas of Sri Lanka to investigate correlations between these test parameters. Correlations were developed between each parameter to reduce the cost of quality controlling by means of regression analysis. The study found a strong correlation between Loss Angeles abrasion value test and Aggregate impact value test. By analysing correlation between tests, mineralogy and rock properties validity of this correlation can be proved for common applicationen_US
