Abstract |
|
In this paper a new method has discussion. This is different content of silica 0wt% 2wt%, 4wt% , 6wt%, 8wt% have been added to bitumen to modify the physical, mechanical and rheological properties of hot mix bitumen . The rheological investigations showed that the complex modulus of base bitumen increases by increasing the percentage of silica from 2 to 6 wt% .Phase angle and rut factor for the silica modified bitumen have also decreased significantly An additional laboratory study was conducted to characterize the performance properties of the corresponding bitumen mixtures based on the resilient modulus, indirect tensile strength, fracture energy, moisture susceptibility, and fatigue life. Overall, the addition of NS material has a positive influence on different properties of the asphalt binder and mixture and can be used to construct durable pavements, thereby reduce the life-cycle costs of the pavement. |
