The utilization of Reclaimed Asphalt (RA) in the road construction sector induces considerable economic and ecological benefits. The blending of the recycled material with new components is believed to be of great importance for the mixture’s properties. An extensive knowledge of the blending of the materials is crucial in optimizing the use of RA, especially at higher recycling rates. In this paper, the applicability of Fourier transform infrared (FTIR) microscopy in attenuated total…

Fatigue Resistance of Bituminous Mixtures and Mortars Containing High Reclaimed Asphalt Content
The aim of this study was to assess whether the inclusion of a RAB can provide at least similar fatigue properties compared to an all-virgin mix, and to evaluate whether the proposed treatment is beneficial for the mixtures with an RAB.
Affinity between Bitumen and Aggregate in Hot Mix Asphalt by Hyperspectral Imaging and Digital Picture Analysis
This study investigated the viability of quantifying the affinity between aggregate and bitumen by means of different imaging techniques. Experiments were arranged in accordance with the
The impact of reclaimed asphalt rate on the healing potential of bituminous mortars and mixtures
Fatigue resistance is of paramount importance for bituminous materials and so it is the effect of applying rest periods, as this is a more realistic representation of the traffic loading. To this e...


Application of FTIR-ATR to Characterization of Bitumen Rejuvenator Diffusion
Fourier transform infrared spectroscopy by attenuated total reflectance (FTIR-ATR) has been applied to laboratory studies of bitumen rejuvenator diffusion. Previous studies have given more
Methods for Analyzing the Chemical Mechanisms of Bitumen Aging and Rejuvenation with FTIR Spectrometry
The recycling of asphalt is a process where old pavement is broken up and used as reclaimed asphalt pavement (RAP) in new asphalt pavement, often with the aid of recycling agents. The goal of asphalt
Experimental study into the fundamental understanding of blending between reclaimed asphalt binder and virgin bitumen using nanoindentation and nano-computed tomography
The properties of asphalt mixtures containing a high amount of reclaimed asphalt are presumed to be strongly influenced by the degree of blending between old and virgin bitumen. As part of a PhD
First Observation of Blending-Zone Morphology at Interface of Reclaimed Asphalt Binder and Virgin Bitumen
One of the challenges in designing recycled asphalt mixtures with a high amount of reclaimed asphalt pavement (RAP) is estimating the blending degree between RAP binder and added virgin bitumen. The
Potential and limits of FTIR methods for reclaimed asphalt characterisation
Abstract In recent years, as a result of both environmental policy and industrial economic strategy, the amount of asphalt pavement that has been recycled has risen dramatically. As a result of this,
Repeatability and sensitivity of FTIR ATR spectral analysis methods for bituminous binders
Bituminous binders as organic materials are prone to aging mainly by oxidation. Aging changes the viscoelastic behavior of the material over time towards higher stiffness and brittleness. FTIR has
Laboratory Observation and Evaluation of Asphalt Blends of Reclaimed Asphalt Pavement Binder with Virgin Binder using SEM/EDS
In this paper, microscopic technique tests were carried out to observe and evaluate the degree of blending between reclaimed asphalt pavement (RAP) binder and virgin binder in hot mixed asphalt
