【Abstract】：To thoroughlyverifythe influenceof thecombinationof wasteengineoil with warm mix technoloyontherheological properties of asphalt，and therebyanalyze the comprehensive performance of warm mix waste engine oil-recycle asphalt，temperature sweep test，low-temperature bending beam rheometer test，and multiple stress creep recovery test were conducted to measure the high-temperature deformation resistance，low-temperature crack resistance，and resistance to permanent deformation under sustained loading of the asphalt treated with both warm mix agent and waste engine oil.The tests indictated that the warm mix waste engine oil-recycled asphalt exhibited superior high-temperature deformation resistance compared to the base asphalt. Its low-temperature performance was beter than that of the base asphalt，and its resistance to permanent deformation was also excellent.The overallperformance met the requirements for asphalt pavement performance.
