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 ...
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 ...
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 ...
Acoustic Performance Evaluation of Dense-Graded Asphalt Pavements in Qatar
(
Hindawi
, 2021 , Article)
There is pressing and growing demand from the public to design and construct roads with a low noise level. This paper investigated the acoustic performance of asphalt pavements in the State of Qatar to assist transport ...
Rheological, Thermal, and Chemical Evaluation of Asphalt Binders Modified Using Crumb Rubber and Warm-Mix Additive
(
American Society of Civil Engineers (ASCE)
, 2022 , Article)
This study evaluates the potential of producing warm-mix asphalt (WMA) using a wax-based additive (Sasobit) in a binder modified using crumb rubber (CR). This binder is formulated for very hot climates and has a grade of ...
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 ...
Comparative Characterization of Field and Laboratory-Aged Binders Modified with Antioxidant Additives and Copolymers Using Fourier Transform Infrared Spectroscopy and Gel Permeation Chromatography
(
American Society of Civil Engineers (ASCE)
, 2022 , Article)
This study investigates the behavior of antioxidant additives and copolymers to an asphalt binder by comparing laboratory-aged (up to 60 h) and antioxidant-modified binders with binders extracted from field cores. To ...
Assessment of Pavement Performance Management Indicators Through Analytic Network Process
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2022 , Article)
Pavement industry is very critical for any public authority looking after the safety and comfort of its citizens because it is the backbone of many transportation networks. Studying the factors that affect the pavement ...
Impact of Aging on the Microstructure of Asphalt Binder Modified with Antioxidant Additives and Copolymers
(
Chinese Society of Pavement Engineering
, 2023 , Article)
The effect of long-term aging on asphalt binders mixed with antioxidant additives and copolymers demonstrated potential for retarding oxidative aging at the nanoscale based on atomic force microscopy (AFM) characterization. ...
Assessment of Critical Project Success Factors for Management of Pavement Construction Using the Delphi Approach
(
American Society of Civil Engineers (ASCE)
