The utilization of reclaimed asphalt pavement material (RAP) is restricted due to the rigidity and maneuverability challenges linked to RAP. This problem is resolved by employing warm mix asphalt (WMA), which enhances the amount of RAP utilized by creating mixtures with equivalent or superior characteristics, such as improved workability and reduced viscosity compared to hot mix asphalt (HMA) at lower temperatures. The aim of this work is to analyze the rheological properties and impact on aging mechanism of asphalt binders mixed with large amounts of Artificial Reclaimed Asphalt Pavement (RAP) produced using Warm Mix Asphalt (WMA) additive and Waste Industrial Oil (IWO) using Fourier transform infrared spectroscopy (FTIR). The VG30 asphalt underwent partial replacement with Rejuvenated RAP, with a weight proportion of 50%. The rheological properties were assessed by the use of a Dynamic Shear Rheometer (DSR), which allowed for the measurement of complex viscosity and PG grading. Additionally, aging simulation was performed utilizing the rolling thin film oven (RTFO) and Oven aging methods. The RTFO test was used to measure the loss of volatiles, while the FTIR test was conducted to analyze the oxidation characteristics. The FTIR spectra investigation revealed the formation of extra C═C, C─O, C═O, and OH bonds as a result of the aging process.

摘要

The utilization of reclaimed asphalt pavement material (RAP) is restricted due to the rigidity and maneuverability challenges linked to RAP. This problem is resolved by employing warm mix asphalt (WMA), which enhances the amount of RAP utilized by creating mixtures with equivalent or superior characteristics, such as improved workability and reduced viscosity compared to hot mix asphalt (HMA) at lower temperatures. The aim of this work is to analyze the rheological properties and impact on aging mechanism of asphalt binders mixed with large amounts of Artificial Reclaimed Asphalt Pavement (RAP) produced using Warm Mix Asphalt (WMA) additive and Waste Industrial Oil (IWO) using Fourier transform infrared spectroscopy (FTIR). The VG30 asphalt underwent partial replacement with Rejuvenated RAP, with a weight proportion of 50%. The rheological properties were assessed by the use of a Dynamic Shear Rheometer (DSR), which allowed for the measurement of complex viscosity and PG grading. Additionally, aging simulation was performed utilizing the rolling thin film oven (RTFO) and Oven aging methods.
