Performance evaluation and preventive measures for aging of different bitumens
TLDR
In this paper, three different bitumens (denoted as A, B and C) were exposed to thermal and ultraviolet (UV) aging at different UV intensities and various anti-aging additives were used to modify the bitumen via melt blending.About:

Applications of Fourier transform infrared spectroscopy technologies on asphalt materials
TL;DR: In this paper, Fourier transform infrared spectroscopy (FTIR) has been widely used as a fast and accurate tool for detecting and analyzing organic materials for several decades since it was initially introduced to study the asphalt material.

Evaluation of asphalt mixtures incorporating electric arc furnace steel slag and copper mine tailings for road construction
TL;DR: In this paper, the suitability of using electric arc furnace (EAF) steel slag and copper mine tailings (CMT) as substitution for conventional aggregates used in pavements for roads and highways was evaluated.
Journal ArticleDOI

Journal ArticleDOI
Comparison by Fourier transform infrared (FTIR) spectroscopy of different ageing techniques: application to road bitumens
TL;DR: In this paper, the authors compared a direct and continued methodological approach of bitumen oxidation process (adapted IR cell), a road ageing, along with two ageing conventional tests: the Rolling Thin Film Oven Test (RTFOT) and the Pressure Ageing Vessel (PAV).
Journal ArticleDOI
Effect of the thermal degradation of SBS copolymers during the ageing of modified asphalts
TL;DR: The change in the properties of the styrene-butadiene block copolymers (SBS) modified asphalt under different ageing conditions has been studied in this paper, where normalized test and rotational viscosities show the effect of the degradation and the modification of the polymer-asphalt interactions with the severity of the ageing.
Journal ArticleDOI
Improving the aging resistance of styrene-butadiene-styrene tri-block copolymer modified asphalt by addition of antioxidants
TL;DR: In this paper, the aging properties of base asphalt and styrene-butadiene-styrene tri-block copolymer (SBS) modified asphalts (PMA) were evaluated using Fourier Transform Infrared (FTIR) spectroscopy.
Journal ArticleDOI
Effect of organo-montmorillonite on aging properties of asphalt
TL;DR: In this paper, the effects of organo-montmorillonite (OMMT) on thermo-oxidative and ultraviolet (UV) aging properties of asphalt were investigated, and the results showed that the viscosity aging index (VAI) and softening point increment (Δ S ) of OMMT modified asphalt decrease significantly due to introduction of OMMT and the ductility retention rate of the modified asphalt is also evidently higher than that of the pristine asphalt after thin-film oven test (TFOT) and pressure aging vessel (PAV) aging.
Journal ArticleDOI
Infrared microscopy investigation of oxidation and phase evolution in bitumen modified with polymers
TL;DR: In this article, the authors studied polymer modified bitumens (PmB) in their original state and after conventional tests claimed to simulate the ageing during the mixing process and several years of road service (RTFOT+PAV).
