Modeling Thermal Conductivity, Thermal Diffusivity and Specific Heat of Asphalt Concrete Using Beta Regression and Mixture Volumetrics
(
Qatar University Press
, 2023 , Conference Paper)
The main objective of this paper is to develop predictive models using Beta regression for laboratory-prepared hot mix asphalt (HMA) specimens' thermal properties, including thermal conductivity (TC), thermal diffusivity ...
Numerical Study on the Pullout Behavior of Steel Fibers in Cement-Based Composites
(
Qatar University Press
, 2023 , Conference Paper)
The interaction between steel fiber and surrounding cement-based matrix and concrete materials is crucial in the behavior of Steel Fiber-Reinforced Concrete (SFRC). This interaction is generally measured through a single ...
Sustainability Driven Strategy for Achieving Sustainable Infrastructure: Musaimeer Pumping Station and Outfall Project
(
Qatar University Press
, 2023 , Conference Paper)
The increasing emphasis on global sustainability issues such as climate change, loss of biodiversity, deforestation, and water scarcity has provided a strong mandate for the construction industry to incorporate sustainable ...
Launching a 148m-Long Tunnel Boring Machine from a 15m-Inner Diameter Shaft
(
Qatar University Press
, 2023 , Conference Paper)
The city of Doha has grown and expanded rapidly in the last 20 years, but this growth has strained the country's infrastructure, including its aging sewerage system and treatment facilities. ASHGHAL has therefore launched ...
The Use of Demolished Concrete Lumps (DCL) in Rectangular CFSTs Under Flexure
(
Qatar University Press
, 2023 , Conference Paper)
This paper investigates the flexural performance of rectangular concrete-filled steel tube (CFST) beams that are partially incorporated with demolished concrete lumps (DCLs). In total, three CFST beams were prepared and ...
Modeling Asphalt Pavement Frictional Properties using Different Machine Learning Algorithms
(
Qatar University Press
, 2023 , Conference Paper)
The objective of this work is to use some machine learning algorithms and test its efficiency in developing models to predict Locked Wheel Skid Trailer (LWST) values from Dynamic Friction Tester (DFT) and Circular Texture ...
A Markovian-Genetic Algorithm Model for Predicting Pavement Deterioratio
(
Qatar University Press
, 2023 , Conference Paper)
Pavement structures are constantly deteriorating due to many distresses, for instance cracks and rutting that are initiated and expanded. Deterioration models of pavement structures is an important component of pavement ...
Ashghal Quality Assurance & Quality Control system - QSD Role in Monitoring & Reporting the Quality Performance in Ashghal Projects
(
Qatar University Press
, 2023 , Conference Paper)
Ashghal has established a robust system of quality control and quality assurance for all projects constructed by Ashghal. Ashghal Departments are supervising a sophisticated system of quality control and quality assurance ...
Ashghal Guidelines for the Evaluation and Repair of Sinkholes
(
Qatar University Press
, 2023 , Conference Paper)
Sinkholes are a common and recurring problem with potential safety risks to road users and authorities. A sinkhole is a void in the ground caused by natural and/or manmade activities, and mainly associated with carbonate ...
Utilisation of Waste Plastics Admix with Laterite Soil for Production of Road Pavement Interlocking Blocks
(
Qatar University Press
, 2023 , Conference Paper)
Plastic wastes are non-biodegradable and hence pile up in refuse dumps and streets constituting an eyesore and menace to the environment. Some of them end up in drainages and waterways where they block water passages ...
