Effect of Recycled Aggregates and Polymer Modified Bitumen on the Marshall Properties of Hot Mix Asphalt- A Case Study

The main objective of this study was to assess the performance and physical properties hot mix asphalt mixes incorporating recycled aggregates from demolished concrete compare them with an unmodified mixture. Using offers potential environmental benefits by reducing load on landfill sites associated waste. Hot were prepared using Marshall mix-design technique, varying proportions (0%, 25%, 50%, 75%) replacing coarse virgin aggregates. resulting compared a control sample. It observed that increase in proportion aggregates, stability decreased. Additionally, number air voids filled mineral increased. However, laboratory tests indicated modified exhibited comparable conventional while providing improved advantages through recovery reuse waste These findings highlight utilizing as sustainable approach pavement construction.
