Determining the binder content in hot mix asphalt (HMA) is essential for ensuring pavement quality and performance. This study compares two methods Ignition Furnace and Centrifuge Extraction to assess bitumen content in HMA mixtures and examine the impact of both methods on aggregate integrity. Two mix types, Asphalt Concrete Base course ACB 28 and Stone Mastic Asphalt SMA 14, were designed using the Marshall mix design system in accordance to AASHTO standards. The optimum bitumen content for each mix was determined to be 4.8% and 6.1%, respectively. However, sieve analysis revealed observable changes in some sieves of SMA14. Findings indicate variability in SMA14 between ignition and centrifuge methods however, statistical analysis does not confirm a significant difference. In contrast, ACB28 exhibits a t-statistic surpassing the critical limit, indicating statistical significant in the result. The p-value is close to the conventional cutoff for significance, suggesting ACB28 likely exhibits a real effect but remains on the boundary of statistical confidence....................
