Characterisation of fatigue resistance of alternative pavement design for the state of Qatar
(
Taylor and Francis - Balkema
, 2014 , Conference Paper)
Asphalt mixtures have been designed in the past in the State of Qatar to safeguard against permanent deformation associated with high temperatures. These mixtures are typically designed to have low content of unmodified ...
Assessment of linear and nonlinear viscoelastic responses of warm-mix asphalt binders
(
CRC Press/Balkema
, 2015 , Conference Paper)
Warm-Mix Asphalt (WMA) technology is widely used in the paving industry due to its impact on reduction of asphalt mixing and compaction temperatures. Characterisation of WMA in the past had focused on evaluating the linear ...
Disruption factor of asphalt mixtures
(
Taylor & Francis
, 2012 , Article)
Typically, aggregate gradation is selected to meet Superpave mix design specification; however, many Superpave mixtures have exhibited deficient field performance. The porosity of the dominant aggregate size range (DASR), ...
State-of-the-art review on sustainable design and construction of quieter pavements-Part 1: Traffic noise measurement and abatement techniques
(
Multidisciplinary Digital Publishing Institute (MDPI)
, 2016 , Article)
Noise pollution due to highway traffic has drawn the attention of transportation agencies worldwide. Noise pollution is an irritant to residents, especially in urban areas near roads with high traffic volume. In addition ...
Virtual environments for improving construction site safety
(
Taylor & Francis
, 2011 , Article)
This paper aims to present a visual simulation technique for improving construction site safety based on virtual construction environments (VCE). Additionally, the paper presents a framework to conduct true ‘what-if’ ...
Performance evaluation of full-scale sections of asphalt pavements in the State of Qatar
(
American Society of Civil Engineers (ASCE)
, 2014 , Article)
The population and economy in the State of Qatar have been increasing in the past 5 years. Accordingly, traffic loading has also increased rapidly, which affected the performance of existing roads and highways. This high ...
Integration of Captivate and JOOMLA: Online demonstration and assessment elearning resources
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2010 , Conference Paper)
The system uses Adobe Captivate [1] to create and generate the learning and assessments materials in PDF format to allow students to access the learning materials and to do the assessment interactively. Each assessment is ...
Mitigation of railway-induced vibration by using subgrade stiffening
(
Elsevier Ltd
, 2015 , Article)
Railway-induced ground vibration is often associated with sites with soft ground. Stiffening of the subgrade beneath the railway track is one particular measure that has potential to reduce the vibration level at such ...
Investigation of Weather Impacts on Pedestrian Volumes
(
Elsevier B.V.
, 2016 , Conference Paper)
This study investigates the impacts of temporal and weather characteristics on pedestrian volumes in a hot climate condition. A major neighborhood located in an urban area in Doha, Qatar was chosen as a case study site. ...
Reducing railway-induced ground-borne vibration by using open trenches and soft-filled barriers
(
Elsevier Ltd
, 2016 , Article)
A trench can act as a barrier to ground vibration and is a potential mitigation measure for low frequency vibration induced by surface railways. However, to be effective at very low frequencies the depth required becomes ...
