The use of waste rubbers as partial aggregates in pavement is important for the lifetime of road, which are more susceptible to degradation from heat and oxygen exposure during the lifetime. The purpose of this work is to study the effect of thermal-oxidative aging of waste rubbers on the road performance and noise reduction ability of the porous elastic road surface (PERS) mixture. The impact of thermal-oxidative aging of waste rubbers on the water stability, dynamic stability at high temperatures, and maximum flexural strain at low temperatures of the PERS mixture was investigated, which were all decreased as aging time increased indicating. Additionally, the sound absorption ability of the PERS mixture initially increased but then decreased with aging time, ultimately falling below that of the unaged samples. It is hoped that this work can provide a new theory for long-life applications of waste rubbers in functional pavement.
