Performance Evaluation of Fatigue and Fracture Resistance of WMA Containing High Percentages of RAP

Sustainability and durability are the key requirements of pavement structure. asphalt structure involves utilization Warm Mix Asphalt (WMA) technologies with addition Reclaimed Pavement (RAP), where performance parameters like fatigue fracture resistance properties etc. Utilizing RAP content in mix increases mixing compaction temperature which may degrade asphalt. Hence, numerous studies have recommended different WMA to decrease containing RAP. The present research work evaluates Hot (HMA) varying percentages Sasobit. Different mixes HMA were designed (0, 20, 40 60%) through Marshall design. Sasobit (organic/wax-based additive) was used as technology prepare at 2, 4 6%). behavior evaluated using four-point bending test, determined Semi Circular Bending (SCB) test laboratory. Fatigue improved increase content, while showed a decreasing trend due stiffer nature Furthermore, identified economical for construction besides other benefits environment friendly mix.
