Using the Statistical Analysis of Carbon Nano-tubes Dispersion in Bitumen Employing MINITAB Software

Nowadays, utilisation of Nano-materials as one of the most recent methods of bitumen modification has attracted attention of many researchers. However, not enough research has been pursued on their mixing with bitumen, because of their dimensions and specific properties. In this study, the carbon Nano-tubes were mixed with bitumen using different mixers and some images were recorded employing a scanning electron microscope. Then, different statistical analyses were carried out on the experiment of penetration degree performed on several samples. The recorded images of mixed samples and the statistical analyses show that the ultrasonic mixer has mixed the carbon Nano-tubes more homogeneously with bitumen compared to other mixers.
