Data for: Unraveling the efficient use of waste lignin as a bitumen modifier for sustainable roads.

The data presented here include: the decomposition analysis of the composite using the Thermogravimetric analysis (TGA) equipment, high-temperature behavior of Lignin bitumen composite by measuring the Temperature sweep curve, Multiple Stress Creep Recovery (MSCR) and Linear Amplitude Sweep (LAS) using the dynamic shear rheometer equipment. The data also includes results from the penetration, softening point test, bending beam rheometer test and tension retardation test. The tests were conducted on both unmodified bitumen (control) and the modified bitumen with lignin (5-10%).
