Investigation of the properties of modified bitumen and stone mastic asphalt mixtures with different contents

In this study, TPE-E polymer additive was used as an alternative to the modified bitumen craton added bitumen TMA application. Three different types of mixing cores were created (1st type SBS added standard type TMA, 2nd type TPE-E, PET, TEA and surgical mask modified TMA, 3rd type TPE-E, PET, TEA and Fiber added TMA), these cores belong to TMA mixtures. material (aggregate, bitumen) tests, Marshall Mix Design values (air gap, intergranular space, optimum bitumen amount, etc.), rutting test, in-direct tensile strength test, dynamic shear rheometer, rotational viscometer test and fatigue resistance test results were compared. The compatibility of the obtained results with the Highways Technical Specification and the effects of these values on the physical properties and performance of the pavement were examined. In addition, cost analyzes of the examined wear layers and pavement models (project and proposed) were made. Keywords: (modified bitumen, TPE-E, waste pet, dynamic shear rheometer, fiber, SBS)
