Thesis on blending of Aggregates for Bituminous Mix Design without conducting individual gradation
Introduction Bituminous mixes like Bituminous Macadam (BM), Dense Bituminous Macadam (DBM), and Bituminous Concrete (BC) require precise gradation of aggregates to ensure the pavement's durability, strength, and workability. This thesis explains the method used to calculate the proportions of aggregates for each mix type, incorporating theoretical and actual retained weights for 6mm and dust. Additionally, adjustments for 6mm and dust for BM, BC, and DBM are discussed to highlight their role in achieving better gradation control. Objectives To explain the methodology for calculating theoretical and actual retained weights for BM, DBM, and BC. To present the rationale for adjustments in 6mm and dust amounts for BM, BC, and DBM. To provide a clear understanding of how the final proportions of aggregates are derived. Data Layout and Structure There are two tables for BM, DBM, and BC. Left-Side Tables: These tables display theoretical retained weights calculated using the passing per...
