Long-Term Performance of Recycled Asphalt Pavement with Recycled Engine Oil Bottom Based on Accelerated Loading Test

The practical performance of recycled asphalt obtained from engine oil bottom (REOB) was evaluated by paving a test road base and REOB-recycled mixture in laboratory, where accelerated loading tests with 700,000 cycles were conducted. During loading, pavement temperature, layer strain, skid resistance, rutting monitored. core material tested after to analyze the index change binder compaction degree mixture. results show that long-term anti-rutting ability is approximately 10% higher than pavement, although anti-sliding force anti-fatigue are poor. A developed model rut time can better predict development trends these parameters cycles. shows only degrade not damage it. 7% REOB has basically same as under cycles, indicating ensure basic performance, while providing economic environmental advantages. These provide reference for application form optimization pavement.
