Aging evaluation of asphalt samples with Low Field Nuclear Magnetic Resonance
(
Elsevier Inc.
, 2017 , Article)
In this study, a recently developed methodology to assess aging of pavements by using Low Field Nuclear Magnetic Resonance (LF-NMR) was applied to asphalt mix samples at different aging states. The ultimate objective of ...
Comparative Characterization of Field and Laboratory-Aged Binders Modified with Antioxidant Additives and Copolymers Using Fourier Transform Infrared Spectroscopy and Gel Permeation Chromatography
(
American Society of Civil Engineers (ASCE)
, 2022 , Article)
This study investigates the behavior of antioxidant additives and copolymers to an asphalt binder by comparing laboratory-aged (up to 60 h) and antioxidant-modified binders with binders extracted from field cores. To ...
Impact of Aging on the Microstructure of Asphalt Binder Modified with Antioxidant Additives and Copolymers
(
Chinese Society of Pavement Engineering
, 2023 , Article)
The effect of long-term aging on asphalt binders mixed with antioxidant additives and copolymers demonstrated potential for retarding oxidative aging at the nanoscale based on atomic force microscopy (AFM) characterization. ...
