Vertical Alignment Optimisation in Highway Design By Means of Mesh Adaptive Direct Search
Author(s) Eray Ozkan, PhD Hediye Tuydes-Yaman, PhD Soner Osman Acar, PhD Abstract Finalising the vertical alignment of a highway geometric design is a critical phase in a highway project and directly affects its construction cost. Generally, a vertical...
A Methodology for Measuring a Local Index of Public Transport Accessibility
Author(s) Khaled Al-Sahili, PhD Khalil Qaisi, MSc Abstract Increasing interest in sustainable development has underlined the importance of accessibility as a key indicator to assess public transport (PT) investments. In several developing countries,...
Effect of Environmental Factors on Performance of Jointed Concrete Pavements
Author(s) Dong-Hyuk Kim Jun-Hyeok Lee Ki-Hoon Moon, PhD Jin-Hoon Jeong, PhD Abstract This study investigated the distress conditions of test sections of concrete pavement that have been used for more than the design life of 20 years. The study was performed...
Corrosiong in Concrete sewers: Crucial research helps keep sewer corrosion at bay
Concrete is the most commonly used material in sewers, especially for large sewer pipes, which can be attributed to its strength, durability and relatively low maintenance costs. However, due to the nature of concrete and the unique sewer atmosphere, corrosion of...

Balancing Railway Network Availability and Engineering Access
Author(s) John Armstrong, BE, MSc, EngD John Preston, BA, MA, PhD Abstract As traffic on Britain's railways has grown, the system is approaching capacity and moving towards 24/7 operation. This increases wear and tear, and reduces access for maintenance,...
Sustainability of High-speed Rail: A Comparative Study
Authors Inara Watson, BSc, MSc Amer Ali, BSc, MSc, PhD Ali Bayyati, BSc (Hons), MSc, PhD Abstract High-speed railways can move passengers and goods cost-effectively and sustainably. However, there is a need to consider the objectives of high-speed rail (HSR)...
Analysing the Effect of Principal Stress Rotation on Railway Rrack Settlement by Discrete Element Method
Author(s) Xuecheng Bian* Wei Li* Yu Qian† Erol Tutumluer‡ Abstract Principal stress rotation induced by moving loads from trains significantly influences railway track settlement accumulation. The stationary cyclic loading commonly adopted to study railway...
