Index properties tests were conducted on bitumen and graphite to determine their suitability. Dynamic viscosity and dynamic shear rheometer were conducted on bituminous binder …

In this study, the effect of graphite used for developing the rheological and conventional properties of bitumen were investigated using various bituminous binder tests.

This involves mixing bitumen with aggregates to create asphalt concrete mixes, typically through a hot mixing process at temperatures over 150 °C. Although other techniques exist, such as using ed bitumen, warm mix and cold mix technology, they are not commonly used, accounting for a small percentage of the total asphalt mix production [5 ...

Again low life of bitumen due to oxidation is another problem. Hence, it is important to use potential modifiers to partially substitute and enhance the life of bitumen and flexible pavements. In this paper use of numerous modifiers and their possible effects on bitumen and bituminous mix strength and toughness are described by researchers.
