Fatigue Performance and Influence Factor for Cold Recycling Mixture With Emulsified Asphalt

In order to study the key influence factors of fatigue performance for cold recycling mixture with emulsified asphalt,the influence rule of fatigue performance was investigated under different stress levels,cement dosage,RAP proportion,emulsified asphalt content and type by using the indirect tensile fatigue test with stress control mode,and finally based on the grey relation entropy analysis,the impact of various factors was quantified and compared. The results show that fatigue performance for cold recycling mixture with emulsified asphalt is significantly affected by penetration and RAP proportion,whereas less affected by emulsified asphalt content and ductility,and least affected by stress level and cement dosage.
