| Since the purpose of wheel tracking test is to find out relative difference of mixture's rut resistance, the wheel is an important part in the test for obtaining a consistent output. This study is performed to examine efficiency of different wheel material, rubber and steel in wheel tracking test. The rubber was inserted as a ring on the outer face of the steel wheel, and thickness of rubber ring was 15mm and 7.5mm and 0mm (steel wheel without rubber), making the total outer diameter 200mm. The objective of this study was to select reliable wheel material type in wheel tracking test at $60^{circ}C$ based on variance in output (rut depth and dynamic stability) and correlation with SD (deformation strength). The result of regression analysis of rut depth with Sd showed that $R^2$ values of wheel rubber thickness of 15mm, 7.5mm and 0mm were 0.7, 0.8 and over 0.9, respectively. In a case of steel wheel (0mm), the highest $R^2$ value was 0.9569. Therefore, the wheel without rubber ring was the best in output consistency level and coefficient of determination $(R^2)$ with deformation strength. Therefore, the steel wheel without rubber ring is suggested as the best choice for wheel tracking test of asphalt concrete. |
