Sirin, Okan; Ohiduzzaman, Md; Kassem, Emad; Hassan, Wahid ( 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 ... -
Comparative Characterization of Field and Laboratory-Aged Binders Modified with Antioxidant Additives and Copolymers Using Fourier Transform Infrared Spectroscopy and Gel Permeation Chromatography
Khan, Mohammad S.; Kassem, Emad; McDonald, Armando; Sirin, Okan; Aston, D. Eric ( 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 ... -
Comprehensive evaluation of long-term aging of asphalt mixtures in hot climatic condition
Sirin, Okan; Ohiduzzaman, Md; Kassem, Emad; Paul, Dalim K. ( Taylor & Francis , 2018 , Article)Aging is an inevitable phenomenon in hot mix asphalt production and during in-service period of flexible pavement operation. This paper presents an experimental evaluation of long-term aging of asphalt mixtures in Qatar. ... -
Evaluation of Federal Highway Administration’s Traffic Noise Model for Pavements in Qatar
Sirin, Okan; Ohiduzzaman, Md; Kassem, Emad ( 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 of traffic noise in the state of qatar
Kassem, Emad; Ohiduzzaman, Md; Sirin, Okan ( 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 ... -
Impact of Aging on the Microstructure of Asphalt Binder Modified with Antioxidant Additives and Copolymers
Khan, Mohammad Solaiman; Kassem, Emad; Aston, D. Eric; Sirin, Okan; McDonald, Armando ( 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. ... -
Influence of temperature on tire-pavement noise in hot climates: Qatar case
Okan, Sirin; Ohiduzzaman, Md; Kassem, Emad ( Elsevier , 2021 , Article)The ambient air temperature greatly influences tire-pavement noise measurements. Therefore, various international standards recommended a temperature correction factor to compensate for noise measurements at varying ... -
State of the Art Study on Aging of Asphalt Mixtures and Use of Antioxidant Additives
Sirin, Okan; Paul, Dalim K.; Kassem, Emad ( 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
Ohiduzzaman, M. D.; Sirin, Okan; Kassem, Emad; Rochat, Judith L. ( 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 ...
