Evaluation of Combined Excavation Waste and Reclaimed Asphalt Pavement Aggregates for Use in Road Bases and Sub-bases
(
OMICS International
, 2014 , Article)
More than 15 million tons of aggregates are imported each year to Qatar from neighbouring countries. Large quantities of waste materials (around 20 million tons/year) from excavation waste, demolition rubble and reclaimed ...
Use of local discarded materials in concrete
(
Elsevier
, 2014 , Article)
Steel slag, a by-product of steel manufacturing, is generated in large quantities in Qatar. In fact, it is estimated that more than 400,000tons of steel slag are generated annually in the country. Gravel, resulting from ...
Recycling of Local Qatar’s Steel Slag and Gravel Deposits in Road Construction
(
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 ...
The Effect of Aluminium Dross on Mechanical and Corrosion Properties of Concrete
(
OMICS International
, 2014 , Article)
It is the objective of this project is to investigate the mechanical and chemical behaviour of new concrete type obtained by adding aluminium dross which is an impure aluminium mixture that results from metals melting and ...
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 ...
The fictitious force method for efficient calculation of vibration from a tunnel embedded in a multi-layered half-space
(
Elsevier
, 2014 , Article)
This paper presents an extension of the Pipe-in-Pipe (PiP) model for calculating vibrations from underground railways that allows for the incorporation of a multi-layered half-space geometry. The model is based on the ...
Disruption factor of asphalt mixtures
(
Taylor & Francis
, 2012 , Article)
Typically, aggregate gradation is selected to meet Superpave mix design specification; however, many Superpave mixtures have exhibited deficient field performance. The porosity of the dominant aggregate size range (DASR), ...
State-of-the-art review on sustainable design and construction of quieter pavements-Part 1: Traffic noise measurement and abatement techniques
(
Multidisciplinary Digital Publishing Institute (MDPI)
, 2016 , Article)
Noise pollution due to highway traffic has drawn the attention of transportation agencies worldwide. Noise pollution is an irritant to residents, especially in urban areas near roads with high traffic volume. In addition ...
Virtual environments for improving construction site safety
(
Taylor & Francis
, 2011 , Article)
This paper aims to present a visual simulation technique for improving construction site safety based on virtual construction environments (VCE). Additionally, the paper presents a framework to conduct true ‘what-if’ ...
Performance evaluation of full-scale sections of asphalt pavements in the State of Qatar
(
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 ...
