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 ...
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 ...
Implementation of mechanistic-empirical pavement analysis in the State of Qatar
(
Taylor & Francis
, 2014 , Article)
The State of Qatar is experiencing tremendous growth in infrastructure including road network and highways. The current methods used in design of asphalt pavements in the State of Qatar are empirical and might not be ...
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. ...
State-of-the-Art Review on Sustainable Design and Construction of Quieter Pavements-Part 2: Factors Affecting Tire-Pavement Noise and Prediction Models
(
MDPI AG
, 2016 , Article Review)
Traffic noise is a combination of noises produced from a number of sources. Of all the traffic noise sources, tire-pavement noise, which is emitted as a result of the interaction of rolling,slipping, or dragging tires and ...
Demonstrating the Worth of Recycled Aggregates - A Case Study from Qatar
(
American Society of Civil Engineers (ASCE)
, 2016 , Conference Paper)
Recycled aggregates are widely used in unbound applications in many countries. However, in some areas the materials available may not meet all the requirements of the local specifications. This is the case in Qatar, where ...
Probabilistic analysis of fatigue life for asphalt mixtures using the viscoelastic continuum damage approach
(
Elsevier Ltd
, 2016 , Article)
Fatigue cracking is one of the most serious distress modes affecting the serviceability of asphalt pavement structures. The inherent variability of asphaltic materials exhibited in fatigue test results, especially for ...
Comparative evaluation of fatigue resistance of warm fine aggregate asphalt mixtures
(
Elsevier Ltd
, 2016 , Article)
Fatigue cracking is one of the crucial distresses in asphalt pavements that affect its service life and rehabilitation process. The resistance of asphalt mixtures to fatigue failure in the laboratory experiments is influenced ...
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 ...
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 ...
