Abstract

This study was conducted to improve the heat performance of bitumen. The effect of eggshells on the performance of bitumen was investigated. Eggshell waste was ground and mixed with bitumen at 1%, 2%, and 3% by weight. Sulfuric acid was used as a catalyst for maximum interaction of eggshells with bitumen. The high heat performance and rutting resistance of modified bitumen formed at 160 degrees C were determined by the Dynamic Shear Rheometer (DSR) test. In addition, the low heat performance of modified bitumen was determined with the Bending Beam Rheometer (BBR) test. It was determined that the high heat performance of modified bitumen increased by 16.22% and the low heat performance (creep values) by 11.43% compared to pure bitumen. In addition, it was determined that the rutting resistance values of modified bitumen increased compared to pure bitumen.
