An Approach for Adjusting the Laboratory-Determined Dynamic Modulus Master Curve of Asphalt Layers Based on Falling Weight Deflectometer Measurements
( Hindawi , 2023 , Article)Structural assessment is critical for designing asphalt pavement overlays, estimating the remaining life of pavements, and selecting an appropriate rehabilitation strategy for existing pavements. The falling weight ... -
Assessment of the Current Frequency Calculation Methods Used in the Determination of the Dynamic Modulus Value in Pavement Design and Analysis
( Qatar University Press , 2023 , Conference Paper)The dynamic modulus |E*| is used in the Mechanistic-Empirical Pavement Design Guide (MEPDG) to express the viscoelasticity of asphalt material at a range of temperatures and loading frequencies. As a result, the current ... -
Characterisation of air voids in w-fam samples using x-ray ct imaging
( CRC Press/Balkema , 2018 , Conference Paper)This study documents the use of high-resolution X-Ray Computed Tomography to characterise air void distribution in Fine Aggregate Mixtures (FAM) prepared using Warm Mix Asphalt (WMA) additives (W-FAM). Specimens were imaged ... -
Comparative evaluation of fatigue resistance of warm fine aggregate asphalt mixtures
( Elsevier Ltd , 2016 , Article)Fatigue cracking is one of the crucial distresses in asphalt pavements that affect its service life and rehabilitation process. The resistance of asphalt mixtures to fatigue failure in the laboratory experiments is influenced ... -
Evaluation and calibration of dynamic modulus prediction models of asphalt mixtures for hot climates: Qatar as a case study
( Elsevier , 2022 , Article)The dynamic modulus (|E*|) of asphalt mixtures is one of the most important inputs in Mechanistic-Empirical (ME) pavement analysis and design. Several models have been developed to predict the dynamic modulus based on ... -
A framework for the analysis of damage and recovery characteristics of asphalt mixtures
( Taylor & Francis , 2020 , Article)This study presents two approaches for evaluating damage and recovery characteristics of asphalt mixtures. The first approach focuses on determining damage by extracting recoverable viscoelastic strain that has no damage ... -
New Technique for Flood Risk Assessment of Sub-Networks in Large Networks Using InfoWorks ICM: A Case Study of Qatar's Full Storm Water Network
( Qatar University Press , 2023 , Conference Paper)The elements of the storm water network are made to safely drain most water during a heavy rainstorm. Flood risk modelling (mathematical modelling) with hydraulic software is a good way to check the network's level of ... -
Pavement Automated Condition Assessment Model Using Unmanned Aerial Vehicle and Convolutional Neural Network
( Qatar University Press , 2023 , Conference Paper)Assessing pavement condition is essential in any efforts to reduce future economic losses and improve the pavement performance. The resulting data are used as a record to evaluate pavement performance and assess their ... -
Rheological evaluation of shortand long-term performance for warm mix asphalt (WMA) binders
( Kluwer Academic Publishers , 2016 , Article)Warm-mix asphalt (WMA) additives are environmentally friendly and cost-effective products that lower the viscosity of bituminous binders to allow reduction of mixing and compaction temperatures in asphalt mix production. ...
