dc.description.abstract Quarry industry is a growing industry because of the need of aggregates for the construction industry. One of the most widely used construction material is aggregate which is mined in quarry mines. Most frequently asked parameters for the quality of quarry aggregates are Loss Angeles Abrasion Value and Aggregate Impact Value, which are unpredictable at the initial stages of quarrying for the rock underneath the surface. Hence, the risk of running the quarry is always there. Therefore this article examines the variation of aggregate properties in quarry mining, based on exploratory core samples. The study is carried out by using core samples from a selected quarry in the western province, Srilanka. This research indicates the relationship between Uniaxial Compressive Strength (U.C.S) and Los Angels Abrasion Value (L.A.A.V), between U.C.S and Aggregate Impact Value (A.LV), and between L.A.A.V and A.LV. correlation between the parameters are indicated, and a relatively strong correlation is found between L.A.A.V and A.LV. these will assist to initially predict some test results based on other test results, and thus save initial expenditure on testing for quality of aggregates. en_US
