Abstract [en]

Asphalt is a temperature sensitive material and generally used in pavement industry as an essential ingredient for asphalt concrete. Viscosity of asphalt is an important factor to characterize its workability which in turn is employed for mixing and compaction of asphalt concrete. Viscosity can be manipulated by modifying asphalt binder with compatible polymeric materials. Thermally induced cracking of flexible pavements is a big problem which is more prominent in cold regions. As the pavement structure tends to shrink under low temperature conditions, asphalt modification is needed to handle this shrinkage without losing cohesion with aggregates. Asphalt modified with used lubricating oil improved the low temperature PG grade but the results were not good for high temperature grade. Modification of aged asphalt with 4% waste cooking oil decreased the viscosity to its un-aged condition. The waste engine oil modification of asphalt decrease the stiffness of binder at low temperatures. Glass transition temperature can be decreased and relaxation capability of asphalt binder can be enhanced using 5% refined waste oil. X-Ray fluorescence spectroscopy of asphalt modified with waste engine oil shows loss of strain tolerance and physical hardening of asphalt binder.
