Abstract
The primary methodology for this research involves conducting a series of fatigue tests on 50/70 bitumen to assess its behaviour under varying thermal conditions. The tests will be carried out using a Dynamic Shear Rheometer (DSR), a widely used apparatus in bitumen testing. The DSR allows for measuring bitumen's rheological properties, such as viscosity and elasticity, under controlled temperature and stress conditions. The 50/70 bitumen samples will be carefully prepared according to standard testing procedures to ensure uniformity. The bitumen will be heated to a specified temperature for testing, and samples will be taken at different thermal conditions to simulate varying environmental scenarios. The bitumen samples will be placed in the DSR and subjected to cyclic loading to simulate the stresses experienced in real-world road conditions. The tests will be conducted at a range of temperatures, typically from low temperatures (to simulate cold weather) to high temperatures (to simulate hot weather). This will allow for the study of the temperature-dependent behaviour of bitumen. The DSR will measure the *complex shear modulus (G)**, which provides information on the stiffness of the material, and the phase angle (δ), which reflects the material’s ability to recover after deformation. These parameters are crucial for assessing the fatigue resistance of bitumen. The fatigue behaviour of the bitumen will be evaluated under repeated loading conditions. The dynamic shear rheometer will apply cyclical stress to the bitumen samples and measure the resulting strain. The number of cycles to failure, defined by a significant decrease in stiffness or an increase in phase angle, will be recorded. The focus will be on understanding how the fatigue resistance of the bitumen is affected by temperature fluctuations. By subjecting the bitumen to these varying conditions, it will be possible to determine at which. Temperatures the material exhibits optimal durability or fails prematurely.
