Influence of track stiffness on track behaviour under vertical load
(University of Zagreb, Faculty of Transport and Traffic Sciences, 2012)
The analysis of track behaviour under vertical load is traditionally based on the presumption that the stresses and deformations in track elements can be determined by the application of the Winkler's Hypothesis. The rail ...
Probabilistic Approach to Evaluate Acceptable Toll Rates in Road Concessions
(National Research Council, 2017)
Countries worldwide make substantial efforts to keep the condition of their road infrastructure at an acceptable level under budgetary constraints. One possible model that enables the delivery of road projects under limited ...
Public-private partnerships in roads and government support: trends in transition and developing economies
(Transportation Planning and Technology, 2013)
Private participation in roads revived strongly in transition and developing countries between 2005 and 2008, growing during the period from US$6.2 billion to US$16.4 billion a year, a new historic peak. However, in view ...
Remuneration models and revenue risk mitigation in road public-private partnership projects - a case study from Serbia
(Routledge, 2017)
As a consequence of renewed interest in attracting private financing for infrastructure investments, public-private partnership (PPP) arrangements are mostly seen as a suitable mechanism for ensuring sound and quicker ...
Vehicle swept path analysis based on GPS data
(Canadian Science Publishing, 2018)
Vehicle swept path analysis presents an essential step while working on at-grade intersection and roundabout designs. Following the intensive development of computer-aided design (CAD) software in the past two decades, ...
Influence of acid treatment and carbonation on the properties of recycled concrete aggregate
(Savez hemijskih inženjera, Beograd, 2018)
Recycled concrete aggregate (RCA), obtained by crushing of original (old) concrete, consists of natural aggregate grains and a cement mortar matrix. The presence of old adhered cement mortar, which has higher porosity than ...
Implementation of Preventive Maintenance in Network-Level Optimization Case Study of the Serbian Low-Volume Road Network
(Transportation Research Record, 2015)
Application of appropriate preventive maintenance treatments, at the right time, extends the service life of pavements, resulting in benefits to road users through increased ride comfort and safety and to road agencies ...
Vulnerability Assessment of Bridges Exposed to Scour
(Transportation Research Record, 2013)
To improve the allocation of funds for the maintenance and risk mitigation of transportation infrastructure, there is a dire need for a simplified, yet sufficiently accurate, methodology to estimate bridge vulnerability ...
Ex post analysis of road projects: resilience to crisis
(Editorial Board EJTIR, 2018)
This investigation aimed to reveal a mechanism of how different road projects' settings respond to macro-economic crisis. Qualitative and quantitative analyses were performed over a sample of 31 European road projects, in ...
Rail defects head checking on the Serbian railways
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2014)
The rail defects due to rolling contact fatigue represent serious safety hazard for rail traffic all around the world. That hazard is more distinct on railways without adequate maintenance strategy, with the increase of ...
