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 ... -
Probabilistic analysis of fatigue life for asphalt mixtures using the viscoelastic continuum damage approach
Sadek, Husam; Masad, Eyad; Al-Khalid, Hussain; Sirin, Okan ( Elsevier Ltd , 2016 , Article)Fatigue cracking is one of the most serious distress modes affecting the serviceability of asphalt pavement structures. The inherent variability of asphaltic materials exhibited in fatigue test results, especially for ... -
Recycling of Local Qatar’s Steel Slag and Gravel Deposits in Road Construction
Taha, Ramzi; Sirin, Okan; Sadek, Husam ( OMICS International , 2014 , Article)Every year, the State of Qatar generates about 400,000 tons of steel slag and another 500,000 tons of gravel as a result of steel manufacturing and washing sand, respectively. The two materials (by-products) are not fully ... -
Rheological evaluation of shortand long-term performance for warm mix asphalt (WMA) binders
Sadeq, Mohammed; Masad, Eyad; Al-Khalid, Hussain; Sirin, Okan; Little, Dallas ( 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. ... -
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).
