Rheological evaluation of shortand long-term performance for warm mix asphalt (WMA) binders
(
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. ...
Condition assessment of sewer pipelines using multi attribute utility theory (MAUT)
(
International Society for Trenchless Technology
, 2016 , Conference Paper)
Many municipalities rely on the interpretation of Closed Circuit Television (CCTV) inspection reports to arrive to a condition assessment grade for the inspected sewer pipelines. The grades stand as a key for decision ...
Microencapsulation of calcium nitrate for concrete applications
(
National Research Council
, 2016 , Article)
The use of encapsulating healing agents that allow the self-healing of concrete has emerged as a potential solution to the current decay and costly maintenance of concrete infrastructure; however, many healing agents are ...
Effect of self-healing calcium nitrate microcapsules on concrete properties
(
National Research Council
, 2016 , Article)
Self-healing concrete with microencapsulated calcium nitrate was investigated. The compressive strength of concrete admixed with microcapsules (as a percentage of the weight of the cement) was tested and compared with that ...
Fatigue characterization of lightly cementitiously stabilized granular base materials using flexural testing
(
American Society of Civil Engineers (ASCE)
, 2016 , Article)
The fatigue characteristics of a lightly stabilized granular material under traffic loading are important considerations for the design of a pavement containing such material. This paper examines the use of flexural testing ...
An inclusive framework for automatic safety evaluation of roundabouts
(
Taylor and Francis Inc.
, 2016 , Article)
This article presents an approach for studying different aspects of traffic safety at roundabouts. An automated safety analysis framework is used to detect different types of traffic conflicts, as well as the inappropriate ...
Investigating the reasons for choosing a major among the engineering students in Qatar
(
IEEE Computer Society
, 2016 , Conference Paper)
The selection of an engineering major is a decision that can influence the career of young students, and possibly their entire fife. The purpose of this study is to understand the factors affecting the selection of an ...
Determination of stiffness modulus and poisson's ratio of lightly stabilized granular materials from indirect diametral tensile testing
(
ASTM International
, 2016 , Article)
Lightly cementitiously stabilized granular materials are generally characterised by their tensile properties that are required for the analysis and design of a pavement structure involving these materials. Tensile properties ...
Progressive image stitching algorithm for vision based automated inspection
(
IEEE Computer Society
, 2016 , Conference Paper)
The increasing number of skyscrapers along with the large number of tall bridges throughout the world also increases the demand of a robust, automated and remotely controlled health monitoring system for civil architectures. ...
Strength optimisation of mortar with CNTs and nanoclays
(
Thomas Telford Services Ltd
, 2016 , Article)
This study explores the use of carbon nanotubes (CNTs) and nanoclays in cement mortars. The paper presents modelling and optimisation of the compressive and flexural strengths of cement mortars containing CNTs and the ...
