Optimizing the Thermal Resistance of Concrete Using The Palm Tree Fronds Fibers
( Qatar Univesrity Press , 2020 , Conference)In the past few years, the issue of global warming has become increasingly visible. Record high as well as record low temperatures are being broken worldwide. Snow is melting in the poles and less sunrays are being reflected ... -
Modelling the Severity of Plastic Shrinkage in Cementitious Materials
( Qatar Univesrity Press , 2020 , Conference)"Plastic shrinkage cracking in cement-based materials occurs between the mixing and the final setting of the mixture, where rapid evaporation of the mixed water is the main cause behind the phenomenon. The induced cracks ... -
Integrated Accident Resilience Framework (IARF) – A Theoretical Approach Using Spatial and Statistical Analysis
( Qatar Univesrity Press , 2020 , Conference)Throughout the world, road accidents have become a nightmare for any local government. Data shows that every 24 seconds someone dies on the road (WHO, 2018). Generally, there are multiple factors causing road accidents ... -
In-Pavement Fiber Bragg Grating Sensor for Vehicle Counting
( Qatar Univesrity Press , 2020 , Conference)Traffic volume studies are conducted to determine the number, movements, and classifications of roadway vehicles at a given location and period. Typically, there are two methods for conducting traffic volume studies: ... -
Evaluating the Operational Impact of Left-Turn Exclusive Number of Lanes: A Case Study from Qatar
( Qatar Univesrity Press , 2020 , Conference)Left-turning movements can significantly reduce the overall capacity of signalized intersections due to the queueing built up. Intersections with heavy left-turning volumes tend to use multiple lanes to accommodate left-turn ... -
Vehicle Inspection Policy and Emission Analysis in Kuwait
( Qatar Univesrity Press , 2020 , Conference)"Technical vehicle inspection centers are widespread in Kuwait. All vehicles should pass the test every two years if not older than six years or every one-year for other vehicles. This study provided an insight into the ... -
Novel Method for Assessing Moisture Damage in Asphalt Mixtures
( Qatar Univesrity Press , 2020 , Conference)Moisture damage is a major cause of early pavement deterioration and often accelerates other distresses such as rutting, fatigue cracking, and raveling. Water infiltrates into the pavement structure through the cracks and ... -
Using Ground Penetrating Radar (GPR) to Evaluate Air Voids Content in Hot Mix Asphalt
( Qatar Univesrity Press , 2020 , Conference)"Air voids content is one of the most important characteristics of Hot Mix Asphalt (HMA). Air voids content that is either too high or too low can negatively impact pavement life and lead to deteriorations such as fatigue ... -
Advanced Freeze-Thaw Assessment of Internally Integrated Concrete with Sodium Acetate
( Qatar Univesrity Press , 2020 , Conference)A new line of research is presented in this study where sodium acetate is used as a protective material for concrete. A newly developed freeze-thaw method that depends on the alteration of temperature and humidity is ... -
Concept Design of Major Roads and Infrastructure in the Center of Doha City: Phase 4 project
( Qatar Univesrity Press , 2020 , Conference)"Doha, the Capital City of Qatar. A cosmopolitan, diverse and ever-growing international hub in the Arabian Gulf. It’s recent and continuous rapid expansion necessitates the careful planning of its roads infrastructure. ... -
An Artificial Intelligence Approach to Estimate Travel Time along Public Transportation Bus Lines
( Qatar Univesrity Press , 2020 , Conference)Public transportation sectors have played significant roles in accommodating passengers and commodities efficiently and effectively. The modes of public transportation often follow pre-defined operation schedules and routes. ... -
Dosage Optimization of Polypropylene Fiber for Strength Enhancement of Cementitious Composites
( Qatar Univesrity Press , 2020 , Conference)"Concrete is the most commonly used materials for construction in Qatar as well as in the world. Exposure to sever environmental conditions causes physical deterioration of concrete structures and significantly affect ... -
Asphalt Rideability Specification and Construction of Expressways in Qatar
( Qatar Univesrity Press , 2020 , Conference)Development of an Expressway network with a smooth ride quality is part of the Qatar 2030 Vision. The Public Works Authority (Ashghal) has placed high importance on the asphalt specification and quality of construction of ... -
Recycled Concrete Used in Subbase in Potential Use for Road Base and Cement Bounded Material (CBM)
( Qatar Univesrity Press , 2020 , Conference)"Structure life cycle and economic developments in Qatar can lead to reconstruction as well as demolition of structures such as buildings and roads. One of the main wastes from demolition work is concrete and reinforced ... -
Using Reclaimed Asphalt and Polymer Modified Asphalt (PMA) to Maximize Cost Saving over the Pavement Life-Cycle in Qatar
( Qatar Univesrity Press , 2020 , Conference)Low performing asphalt mixes along with poor construction practices reduce the pavement serviceability and lead to early failure under repetitive traffic. Government agencies are sometimes urged to implement maintenance ... -
Developing Assessment Framework for Strategic Transportation Projects in Qatar
( Qatar Univesrity Press , 2020 , Conference)This paper presents Transportation Assessment Framework and process for selecting, defining, and naming assessment criteria to be used in transport appraisal. The approach is based on a review of national and international ... -
Site-Specific Traffic Loading Estimation Challenges in Structural Pavement Design Process in Qatar: A Case Study
( Qatar Univesrity Press , 2020 , Conference)Upon the design of any pavement structure, three fundamental external design parameters have to be considered throughout the design process: the characteristics of the subgrade, traffic loads, and environmental conditions. ... -
Characterization of Asphalt Mixtures in Qatar
( Qatar Univesrity Press , 2020 , Conference)The State of Qatar went through a massive road construction program in the last decade as part of the ongoing development of its infrastructure and road transport network. Construction of roads in Qatar generally utilizes ... -
