Performance Evaluation of Aged Asphalt Pavement Binder through Rejuvenators
نویسندگان
چکیده
Natural resources are declining due to rising infrastructure, renovation, demolition, and recycling of existing structures that necessitate sustainable development. It urges the researchers modify aged asphalt binder in enhance performance life asphaltic pavements. The aim this research study is reutilize recycled materials through rejuvenation. This utilizes Cereclor rejuvenate collected from explore its transformation by comparing it with parent similar grade. Different types tests, such as basic physical properties, saturates, aromatics, resins, asphaltenes (SARA) analysis for fractional composition, bending beam rheometer (BBR), dynamic shear (DSR) rheological properties applied investigate these effect on performance. results show rejuvenator improved composition binder. significantly asphaltene contents reduced up 18% addition optimum dosage (7.5%) rejuvenator. colloidal instability index was decreased 0.74 0.43 value changing unstable stable structure. In addition, at a wide range temperatures. has potential soften (7.5%), indicated structure, properties. Furthermore, been concluded can be utilized industry resolve disposal issues lead promote

متن کاملGPR Monitoring System for Evaluation of Asphalt Pavement
To evaluate the condition of asphalt pavement road, two GPR systems with different frequency band were mounted in the trailer type vehicle. The GPR system with higher frequency band was used to measure the thickness of the asphalt layers and the other system with lower frequency band was used to detect the air cavity located beneath the asphalt pavement.

متن کاملEvaluation of the Cooling and Pavement Performance of Basic Oxygen Furnaces Slag Used in Asphalt Mixture
The basic oxygen furnace slag (BOF) was wide used in road construction, but there was a lack of characteristics in different asphalt mixtures. This study investigates the properties of hot-mixed asphalt (HMA) containing stone mastic asphalt (SMA), porous asphalt (PA) and dense-graded BOF as a partial substitution for natural aggregates. The purpose of this study is to evaluate various BOF slag ...
