In this study, a limestone rock core specimen with 6.94 cm x 4.95 cm dimensions was exposed to tensile force
by Brazilian test and rough surfaces were obtained. Following the Brazilian test, roughness angles were
measured by a laser scanner along one side of the rock specimen. For this purpose, Nextengine 3D Desktop
scanner was used. The 17 profiles were studied along the width of the core with a 0.3 mm interval.
Approximately 10000 points produced for each profile, some of them are in the “+” and some are in the “-”
direction along each profile. Maximum and minimum roughness angles are calculated as 65.580 and 1.56x10-5
degree respectively. The average roughness angle value of the profiles is 13.870. The percentage of the
roughness angle between 13 and 14 degrees were 2.65% and 2.70% for “-” and “+” directions on the rock
surface, respectively. Mathematical analyses of 17 profiles showed that roughness profiles can be expressed by
21st – 30th degree polynomial equations with approximately 10-4 degree standard deviation.
