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 ...
Aging evaluation of asphalt samples with Low Field Nuclear Magnetic Resonance
(
Elsevier Inc.
, 2017 , Article)
In this study, a recently developed methodology to assess aging of pavements by using Low Field Nuclear Magnetic Resonance (LF-NMR) was applied to asphalt mix samples at different aging states. The ultimate objective of ...
Evaluation of Federal Highway Administration’s Traffic Noise Model for Pavements in Qatar
(
Springer Nature
, 2020 , Book chapter)
Traffic noise is an irritating problem especially for residents near major transportation corridors. It’s in the interest of transportation agencies to check the noise level to develop measures to reduce noise if it exceeds ...

Nanotechnology has contributed significantly to different subfields of the construction industry, including asphalt pavement engineering. The improved properties and new functionalities of the nanomaterials have provided ...
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 ...
Evaluation of traffic noise in the state of qatar
(
CRC Press/Balkema
, 2018 , Conference Paper)
Mitigating traffic noise is a major concern for transportation departments worldwide. A number of noise mitigation procedures are recognized to control noise emitting from traffic stream. However, noise reduction potential ...
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 Study on Aging of Asphalt Mixtures and Use of Antioxidant Additives
(
Hindawi
, 2018 , Article)
The detrimental effects of hardening in asphalt pavements were first recognized by pioneering pavement engineers in the 1900s and have been studied extensively during the last 70 years. This hardening process, referred to ...
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 ...
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 ...
