Abstract
Abstract To fully restore the performance of waste SBS modified asphalt mixture, better realize its recycling and application in high-grade pavement, achieve the concept of sustainable green development of asphalt pavement. In this paper, the synergistic effects of bio-rejuvenator and active isocyanate rejuvenators (including hexamethylene diisocyanate (HDI), diphenyl-methane-diisocyanate (MDI) and toluene-2, 6-diisocyanate (TDI)) on the chemical structure, physical and rheological properties of aged SBS modified bitumen were thoroughly investigated. Fourier infrared spectrum and Gel permeation chromatography analysis indicate the isocyanate groups of active rejuvenators react with hydroxyl or carboxyl group from the degraded SBS segments to form new amide groups that can reconnect the broken segments of aged SBS and partly restore its molecular weight distribution. From physical and rheological properties, bio-rejuvenator can restore the low-temperature properties by rebalancing the colloidal structure of aged binder, meanwhile, active rejuvenators can greatly improve the high-temperature performance of rejuvenated SBS modified bitumen with bio-rejuvenator through reconnecting the broken segments of aged modifier SBS. Furthermore, MDI with benzene ring structure is more conducive to enhancing the high temperature rutting resistance of rejuvenated SBS modified bitumen. While HDI can bring some flexible segments into the restored structure of SBS, which is more beneficial to improve its low-temperature cracking resistance of rejuvenated binder. And the fluorescence images further demonstrate isocyanate rejuvenators can partly restore the crosslinking network structure of aged modifier SBS in rejuvenated SBS modified bitumen. This research would be conductive to promoting the application of rejuvenated SBS modified bitumen into the construction of high standard pavement.

Abstract Large amount of waste asphalt mixture will be produced in the process of pavement renovation and maintenance, and the waste asphalt mixture recycling can be achieved through rejuvenation. In this paper, four rejuvenators (vacuum stream oil, cashew shell oil, corn oil and waste engine oil) with different chemical composition were selected to rejuvenate aged SBS modified bitumen (ASMB). The influence of different rejuvenators on the rheological properties of rejuvenated aged SBS modified ...

Abstract Profound progress has been made in bio-rejuvenators to enhance aged asphalt's low temperature performance and reduce its high temperature viscosity. However, limitation still exists in the knowledge how long service life of rejuvenated asphalt is and whether regeneration is effective since aging behavior of rejuvenated asphalt is neglected. Furthermore, aging evaluation is based on different tests dependent on temperature, which may lead to various results. This study aims to evaluate t...

The aging of bitumen seriously affects the service life of bituminous pavements. At present, there are many related researches on bitumen aging, but most of them focus on aging endured in indoor surroundings and conditions. Therefore, the conclusions obtained cannot reflect the actual aging changes of bitumen in bituminous pavements in service. In order to study the comprehensive aging process and mechanism of bitumen under the influence of service, we studied bridge deck, traffic lane, and ramp...

Abstract The objective of this study is to investigate the possibility of using bio-oil derived from waste wood as a rejuvenator to recycle aged asphalt binders. In this study, petroleum asphalt of PG58-28 was selected as the base binder. The bio-oil rejuvenators with concentrations of 10%, 15% and 20% by weight were added into the Pressure Aging Vessel (PAV) aged base binder to prepare the bio-rejuvenated asphalts. Through the chemical compounds analysis of the bio-oil using the Gas Chromatogra...

Abundant studies are using Attenuated Total Reflection (ATR) Fourier Transform infrared spectroscopy to quantitatively evaluate the aging extent of Styrene–Butadiene–Styrene (SBS)-modified asphalt (SBSMA). However, most currently employed SBS characteristic indexes merely represent the SBS concentration within SBSMA and may fluctuate during aging because of the poor compatibility between SBS and bitumen. In this study, a new index calculated by dividing polybutadiene infrared peak intensity by p...

Abstract Research on Life Cycle Assessment (LCA) was initially performed to analyze specific products; however, it evolved to assess environmental impacts of more complex systems, such as roads. In this, the construction, use and maintenance stages are usually considered. The results of different studies revealed that all stages have relevant environmental impacts like topsoil loss, change in the use of land, modification of natural drainage and groundwater patterns, landslides, erosion, sedimen...

Abstract This study developed molecular dynamics (MD) models to study the rejuvenator diffusion behavior and its impact on molecular structures and thermodynamic properties of asphalt binder in Reclaimed Asphalt Pavement (RAP). A two layered model was developed to study the inter-diffusion process between rejuvenator and RAP binder. Results show that the inter-diffusion process can be described by Fickian equation. Molecular Dynamics (MD) simulations yield reasonable diffusion coefficient which ...
