Modeling Asphalt Pavement Frictional Properties using Different Machine Learning Algorithms
(
Qatar University Press
, 2023 , Conference Paper)
The objective of this work is to use some machine learning algorithms and test its efficiency in developing models to predict Locked Wheel Skid Trailer (LWST) values from Dynamic Friction Tester (DFT) and Circular Texture ...
A Markovian-Genetic Algorithm Model for Predicting Pavement Deterioratio
(
Qatar University Press
, 2023 , Conference Paper)
Pavement structures are constantly deteriorating due to many distresses, for instance cracks and rutting that are initiated and expanded. Deterioration models of pavement structures is an important component of pavement ...

Ashghal Guidelines for the Evaluation and Repair of Sinkholes
(
Qatar University Press
, 2023 , Conference Paper)
Sinkholes are a common and recurring problem with potential safety risks to road users and authorities. A sinkhole is a void in the ground caused by natural and/or manmade activities, and mainly associated with carbonate ...
Utilisation of Waste Plastics Admix with Laterite Soil for Production of Road Pavement Interlocking Blocks
(
Qatar University Press
, 2023 , Conference Paper)
Plastic wastes are non-biodegradable and hence pile up in refuse dumps and streets constituting an eyesore and menace to the environment. Some of them end up in drainages and waterways where they block water passages ...
Marine Dredging Sediments Valorization in Self-Compacting Concretes
(
Qatar University Press
, 2023 , Conference Paper)
Rock and eroded soil are transported by wind, tide, and human action (development works), and deposited as sediment in ports, estuaries, and rivers. The sediment accumulation at the bottom of ports disrupts maritime ...
Impact of the Fiber Distribution Characteristics on the Uniaxial Behaviour of Fiber-Reinforced Composites- An Experimental Study
(
Qatar University Press
, 2023 , Conference Paper)
The demand for development of fiber-reinforced composites has enhanced as the practise of integrating fibres into concrete has become prevalent over the past few decades.. The intersection zone where the fiber crossing the ...
Planning and Implementing of Effective Enabling Works for a Successful TBM Tunnelling Project
(
Qatar University Press
, 2023 , Conference Paper)
The outfall tunnel, which forms part of the Musaimer Pump Station and Outfall project (MPSO), is a 10.2 km long subsea tunnel that extends from the south coast of Doha, starting onshore, and continues under the Arabian ...
Influence of Pier Stiffness on Track-Bridge Interaction
(
Qatar University Press
, 2023 , Conference Paper)
The bridge is a common engineering structure over which a rail track is often laid. With the introduction of continuous welded rail (CWR), major rail tracks have shifted worldwide from jointed rail to continuous welded ...
