| contents | Bitumen and the Potential benefits of incorporating Eggshell powder and Cement powder as fillers in asphalt mixtures. The research involves laboratory experiments to evaluate the physical and Marshall properties of the bitumen, including penetration, softening point, ductility, viscosity, Marshall stability value. The moisture susceptibility of the bitumen is investigated by conducting the Retained Marshall test on asphalt specimens both in unaged and aged bituminous concrete mixes. The results indicates that aged bitumen exhibits higher moisture susceptibility compared to unaged bitumen, with a significant decrease in Marshall stability values for both VG30 and NRMB 70 grade bitumen. Additionally, VG30 grade bitumen shows higher moisture susceptibility than NRMB 70 grade bitumen. The findings suggest that the aging of bitumen has a considerable impact on its moisture susceptibility and that the grade of bitumen can also affect its resistance to moisture damage. The use of alternative materials as fillers has gained attention in recent years due to their potential to enhance the performance and sustainability of asphalt pavements. The experiment involves a series of laboratory tests to assess the effects of eggshell powder and cement powder on key properties of asphalt mixtures. The study evaluates the impact of these fillers on various performance parameters, including Marshall stability, flow, volumetric properties, and moisture susceptibility of the asphalt mixtures. The laboratory testing involves preparing asphalt mixtures with fillers exchanged and conducting mechanical tests following established standards. The results are compared with control samples containing only conventional fillers to assess the influence of the alternative fillers on the mixture's properties. |
