The Influence of Eggshell as Coarse Aggregate Replacement in Hot Mix Asphalt

Hot Mix Asphalt (HMA) is the most commonly used in Malaysia for highways, interstates and roads due to its flexibility, economical, strong provide safe riding quality road users. Over years, increase of damage on pavement has become a severe issue although did not achieve design life. Hence, reduce defect, an improvised structures needed. Various studies have been conducted identify new materials that can be as replacement hot mix asphalt. In this research, purpose evaluate performance eggshell coarse aggregate The gradation mixture AC14. weight total mixing aggregates 1200g while grade bitumen 60/70. samples were mixed with various percentages 0%, 5%, 10%, 15% 20% by size 5mm. laboratory tests carried out determine properties included, impact value crushing value. Besides, penetration softening point also performed bitumen. Several types test towards samples, which are Marshall Test, Indirect Tensile Strength Cantabro Test. results exhibit conventional asphalt more effective than modified mixture. was enough improvement stable
