Özet

In ancient times, the most widely used rocks, especially in construction of roads and monuments, were sedimentary and

magmatic rocks. Natural stones used in the buildings and historical monuments are subjected to atmospheric effects such as

freeze-thaw, salt crystalisation and wetting and drying cycles which accelerates abrasion. Therefore, wear resistance of natural

stone materials is important for selection of suitable materials in engineering projects. In order to investigate the effect of

deterioration on abrasion properties of natural rock samples, three different abrasion tests (Böhme abrasion (BA), wide wheel

abrasion (WWA) and aggregate impact value (AIV)) were applied to undeteriorated and artificially deteriorated (samples were

subjected to accelerated weathering tests (AWT)) natural rock samples in this study. For the first time, the relationship between

AIV-WWA and BA-AIV tests was experimentally investigated. Consequently, the relationships among BA-WWA, BA-AIV

and AIV-WWA values were examined, the empirical formulas showing these relationships were developed and high correlations

(R2 > 0.80) were obtained. Finally, an abrasion class was proposed using classification ofWWA for determining BA and AIV of

natural rock samples in this study.
