Özet:    Civil engineers should know physical and mechanical properties of stone material which is used as construction material. Determination of abrasion loss is very important at design of pavements of airports, highways harbors etc. The Los Angeles (L.A.) abrasion test is a common test method used to indicate aggregate abrasion characteristics. However Los Angeles test is a time consuming and expensive test. In this work, abrasion loss of stone samples is determined using only simple laboratory tests. For this purpose, 5 different limestone samples are used. Densities (gn), porosities (n), water absorption ratios by volume (Sn), Schmidt rebound values (NL), P and S wave velocities (vp,vs), Unconfined compression strengths (UCS) and abrasion loss percentages (LA500) of all samples are determined. Statistical analyses are conducted by using these values. High determination coefficient (R2=0.99) is obtained by using all test results. However, using the results of index tests, determination coefficient is calculated as (R2=0.96).
