Improvement of the physical and mechanical properties of crushed stone used in the construction of asphalt concrete pavements

This paper presents research on improving the physical and mechanical properties of crushed stone used in asphalt concrete pavements. The study focuses on parameters such as particle size distribution, dust contamination, and adhesion between aggregate and bitumen. Laboratory tests were conducted using a special additive called “TITAN” to enhance the adhesion of the binder to the stone surface. The results demonstrate that the additive significantly improves bonding and overall pavement performance.
