A New Framework for Addressing High-level Decisions Related to Sustainable Transportation Development
( Taylor and Francis Ltd. , 2019 , Article)Stakeholders in the transportation industry have been concerned with sustainability. However, transportation decision makers have had difficulty in incorporating sustainability into transportation infrastructure decisions ... -
An economic loss model for failure of sewer pipelines
( Taylor and Francis Ltd. , 2018 , Article)Estimating the costs of failure for sewer pipelines is usually accompanied with uncertainties because of the difficulty in capturing the relationship between the physical and economical characteristics of failed pipelines. ... -
Analysis of change orders in Qatari construction projects
( Taylor and Francis Ltd. , 2017 , Article)Change orders affect the performance of construction projects and may induce significant cost overruns. The paper identifies the main causes/factors that lead to change orders in Qatari construction projects. It also ... -
Assessment of abnormally low tenders: a multinomial logistic regression approach
( Taylor and Francis Ltd. , 2017 , Article)This study was performed in order to reveal factors affecting abnormally low tenders (ALTs) and to minimize negative effects of them. A thorough literature review was carried out to observe past research about the reasons ... -
Assessment of delay factors in construction of sport facilities through multi criteria decision making
( Taylor and Francis Ltd. , 2019 , Article)The construction of sports facilities widened drastically as the number of sport events gradually increased during the last two decades in the global environment. The requirements of International Federations to host these ... -
Condition assessment model for sewer pipelines using fuzzy-based evidential reasoning
( Taylor and Francis Ltd. , 2018 , Article)A condition assessment model for gravity and pressurised sewer pipelines using Fuzzy Set Theory (FST), and Evidential Reasoning (ER) with the aid of Fuzzy Analytical Network Process (FANP) integrated with Monte-Carlo ... -
Effect of ageing on asphalt binders in the State of Qatar: a case study
( Taylor and Francis Ltd. , 2017 , Article)Ageing of asphalt binders has a significant impact on the rheological properties of asphalt binders and thus affects the performance of asphalt pavements. The rate of binder ageing is accelerated at high temperatures. This ... -
Effect of crushable blockouts on a full-scale guardrail system
( Taylor and Francis Ltd. , 2017 , Article)Since the performance of the guardrail system depends in part on the compatibility of vehicle-to-roadside hardware, it is important to improve the interaction of the vehicle with the guardrail system by adding more compliance ... -
Engineering instructors' professional agency development and identity renegotiation through engaging in pedagogical change towards PBL
( Taylor and Francis Ltd. , 2021 , Article)This qualitative longitudinal study explored three engineering instructors' professional agency in implementing project-based learning (PBL), including multiple sets of data (18 interviews, observations, and written ... -
Integrated performance assessment model for water distribution networks
( Taylor and Francis Ltd. , 2016 , Article)The American infrastructure report card in 2013 rated the US water system infrastructure with grade of ‘D’. The Canadian infrastructure report card in 2012 stated that around 15.4% of Canada’s water infrastructure has a ... -
Investigating the effect of using softer rail-pads on ground-borne vibration from underground railways
( Taylor and Francis Ltd. , 2023 , Article)In this study, a series of vibration measurements were performed on a section of one of the lines of the Doha Metro to explore the effect of changing rail-pads from conventional higher stiffness under-rail pads to lower ... -
Linear and nonlinear viscoelastic and viscoplastic analysis of asphalt binders with warm mix asphalt additives
( Taylor and Francis Ltd. , 2018 , Article)Warm-Mix Asphalt (WMA) is a widely used product, which proved a contribution to the reduction in asphalt mixing and compaction temperatures. This reduction leads to lower fuel consumption and smoke emission in asphalt ... -
Methods and Techniques Used in Significant Restoration Projects in Qatar
( Taylor and Francis Ltd. , 2018 , Article)The large number of conservation and restoration works recently completed in Qatar show that there exists a need to enhance appreciation of the local architectural and building traditions, as a way of bringing to light the ... -
Multiobjective optimization model for scheduling of construction projects under extreme weather
( Taylor and Francis Ltd. , 2016 , Article)Extreme weather significantly impacts construction schedules and costs and can be a source of schedule delays and budget overruns. A multi-objective optimization model, presented herein for the scheduling of construction ... -
Prediction and sensitivity analysis of CNTs-modified asphalt's adhesion force using a radial basis neural network model
( Taylor and Francis Ltd. , 2019 , Article)The expected longer service life of modified asphalt can be jeopardized by different environmental factors, such as moisture, oxidation, etc. which affect the desired properties by altering the adhesive property. An insight ... -
Retarding aging of asphalt binders using antioxidant additives and copolymers
( Taylor and Francis Ltd. , 2019 , Article)The rheological properties of asphalt binders change with aging. Aging is accelerated at elevated temperatures due to binder oxidation, leading to fatigue cracking and eventually pavement failure under heavy and repeated ... -
Simulation-based deterioration patterns of water pipelines
( Taylor and Francis Ltd. , 2019 , Article)Water pipelines deteriorate overtime due to several distressing factors. To keep water pipelines in good condition, municipalities need to use reliable and credible deterioration models and inspection plans to better manage ... -
