(
Elsevier B.V.
, 2017 , Article)
Tortuosity is a parameter that plays a significant role in the characterization of complex porous media systems and it has a significant impact on many engineering and environmental processes and applications. Flow in ...
Modelling of Asphalt's Adhesive Behaviour Using Classification and Regression Tree (CART) Analysis
(
Hindawi Limited
, 2019 , Article)
The modification by polymers and nanomaterials can significantly improve different properties of asphalt. However, during the service life, the oxidation affects the constituents of modified asphalt and subsequently results ...
Evaluation of Noise Performance of Multi-Lane Highways in the State of Qatar
(
Institute of Physics Publishing
, 2019 , Conference Paper)
In recent years, a growing number of people are complaining to transportation authorities for the traffic noise as a result of increased traffic volume on the highways. Therefore, transportation authorities are actively ...
A comparison of ground vibration due to ballasted and slab tracks
(
Elsevier Ltd
, 2019 , Article)
With the development of non-ballasted track forms (often referred to as slab tracks) over the few last decades, it is important to understand their behaviour with respect to ground-borne vibration compared with the traditional ...
Numerical Evaluation of Dynamic Response by Using Modified Newmark’s Method
(
Jordan University of Science and Technology
, 2019 , Article)
It is well known that the Newmark’s method is considered one of the most popular methods for structural
dynamic analysis. In this study, starting from the basic Newmark’s method, a new accurate method is
investigated and ...
Enhancing the corrosion resistance of reinforcing steel under aggressive operational conditions using behentrimonium chloride
(
Nature Research
, 2019 , Article)
Aggressive operational conditions e.g. saline media and acidic gases, e.g., CO2 can increase the corrosion rate of reinforcing steel. Accordingly, the necessity to protect the steel under the above conditions without ...
