Long-term oxidative ageing occurs in asphalt pavements when they are exposed to the ambient environment for extended periods. This ageing phenomenon is dependent on multiple physical fields, including heat transfer, oxygen diffusion from air into interconnected air voids of asphalt pavement, oxygen diffusion from air void channels to asphalt mastic...
Oxidative ageing in field asphalt pavements is a complex process with coupled multiple physics. This parametric study uses Multiphysics modelling approaches to evaluate the effects of material thermal properties, air voids content and distribution, mastic coating thickness, oxygen accessibility and binder oxidative kinetics on the spatial and tempo...
Long-term field ageing of asphalt pavement plays a vital role in limiting the pavements’ service life. Models have been established to represent the multiple physics that contribute to the ageing of asphalt pavement, including: (1) heat transfer to determine pavement temperature profile, (2) diffusion of oxygen from the air into the connected air v...
The aim of this study was to investigate the effects of different anti-ageing compounds (AACs) on the oxidative stability, rheological and mechanical properties of bitumen. Modified bitumen samples containing six different AAC combinations, with five samples containing Irganox acid (3,5-di-tert-butyl-4-hydoxyphenylpropionic acid), a hindered phenol...
This study presents research on laboratory production and experimental characterisation of an alternative bitumen using municipal waste plastics. Six different waste plastics (A1 - A6) produced by a local waste recycling manufacturers were selected and characterised to investigate their feasibility in modifying the bitumen binders. Thermal characte...
When exposed to the ambient environment for an extended period, bitumen ages and causes the failure of asphalt pavement, the addition of anti-ageing compounds (AACs) to bitumen binders can prolong the service life of the pavement. This study investigates the effects of anti-ageing compounds on the fatigue performance of bitumen when subjected to di...
This paper investigates the effect of different anti-ageing compounds (AACs) on the oxidation kinetics of bitumen using Fourier Transformation Infrared (FTIR) spectroscopy. Twenty different AACs were examined, including new and existing AACs for bitumen and polymer products. The AACs were mixed with bitumen to fabricate thin film samples of AAC-mod...
This paper investigates the effect of anti-ageing additives on the oxidation kinetics of bitumen using Fourier Transformation Infrared Spectroscopy technique (FTIR). Twenty different anti-oxidant compounds were added to bitumen (asphalt binder) and subjected to laboratory oven ageing conditioning. Those modifiers included a few known anti-ageing ma...
This work presents a study on intermediate pyrolysis of the organic fraction of municipal solid waste (OFMSW) and characterisation of organic liquid product (pyrolysis oils) with particular focus on aging and rheological characteristics. The feedstock was a real municipal waste sample received from a local waste treatment plant. Shredded into small...
The study aims to investigate the negative effect that the dust storms leave on the human health in general and on the traffic safety as well. Five represented samples of the dust have been collected from the storms which occurred during (2009 and 2010) in Tikrit city/ north of Iraq to find it's particle size distribution, existence of heavy metals...
This research deals with the behavior of rectangular footing on geogrid reinforced sand by means of small experimental scale models. Many parameters that effect on the bearing capacity have been studied such as the number of geogrid layers, depth of the topmost geogrid layer, the vertical distance between the constitutive layers of geogrid, relativ...
Develop a multi-physics finite element modelling framework to predict the long-term ageing performance of asphalt pavement; run a multi-disciplinary investigation to understand the ageing mechanism of asphalt binder; and propose an evaluation protocol to screen anti-ageing compounds-modified bitumen for use in industrial applications to prolong asphalt pavements service life.
