An Approach for Adjusting the Laboratory-Determined Dynamic Modulus Master Curve of Asphalt Layers Based on Falling Weight Deflectometer Measurements
Alfarra, Mohammed; Sirin, Okan; Sadeq, Mohammed; Masad, Eyad ( 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 ... -
Evaluation and calibration of dynamic modulus prediction models of asphalt mixtures for hot climates: Qatar as a case study
Ahmad, Al-Tawalbeh; Sirin, Okan; Sadeq, Mohammed; Sebaaly, Haissam; Masad, Eyad ( 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
Sadeq, Mohammed; Huang, Chien Wei; Masad, Eyad; Al-Khalid, Hussain; Sirin, Okan ( 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 ... -
Performance evaluation of full-scale sections of asphalt pavements in the State of Qatar
Sadek, Husam; Masad, Eyad; Sirin, Okan; Al-Khalid, Hussain; Hassan, Khaled ( 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 ... -
Rheological, Thermal, and Chemical Evaluation of Asphalt Binders Modified Using Crumb Rubber and Warm-Mix Additive
Roja, K. Lakshmi; Aljarrah, Mohammad Fuad; Sirin, Okan; Al-Nuaimi, Nasser; Masad, Eyad ( 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 ...
