Management of stresses in the rails on railway bridges / Upravljanje naponima u šinama na železničkim mostovima
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2018)
This paper analyses the stresses in continuous welded rails on bridges including the aspect of fatigue of rail steel. Furthermore, it examines the possibility to avoid rail expansion joints, while simultaneously exploiting ...
Data driven model for prediction of rail traffic
(Faculty of Mechanical Engineering, Niš, 2014)
The rail system, as a system with high capacity, the least air and water pollution, solvable noise and vibration emission problem and the least space usage, is competitive with other modes of transportation. In addition, ...
Rail inspection of RCF defects
(Croatian Metallurgical Society, 2013)
Rail defects due to rolling contact fatigue (RCF) threaten the traffic safety around the world. That hazard is more distinct on railways without adequate maintenance strategy. Realization of interoperability of European ...
Integration of Materials Science-based Performance Models into PMS
(Wiley Blackwell, 2016)
The integration of materials science-based performance models obtained from laboratory performance testing and modeling into the lifecycle assessment of road pavements is a futureoriented approach for the improvement of ...
Influence of climate conditions on stresses in CWR on the bridges in Serbia / Klimatski uticaji na napone u kontinualno zavarenim šinama u kolosecima na mostovima u Srbiji
(Savez inženjera i tehničara Srbije, Beograd, 2019)
Vehicle/track/bridge interaction causes additional stresses in CWR on the bridge, which include stress in rails due to temperature changes in the bridge deck, vertical bending of bridge deck, and braking/acceleration of ...
Harmonized European norms for asphalt mixtures / Harmonizovane evropske norme za asfaltne mešavine
(Savez građevinskih inženjera Srbije, Beograd, 2010)
The paper presents the new approach implemented through harmonised European norms to production and quality control of asphalt mixtures and componential materials. Harmonized norms were developed based on EU Directive on ...
Measurement uncertainty: Concept and procedural steps for quantification / Merna nesigurnost - pojam i proceduralni koraci pri kvantifikaciji
(Srpsko društvo za puteve VIA-VITA, Beograd, 2010)
The paper presents the procedure for estimation of measurement uncertainty, which is one of basic requirements of standard SRPS ISO/IEC 17025, applied in accredited laboratories for testing and calibrations. The concept ...
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 ...
Одређивање отпорности на замор асфалтних узорака ојачаних геомрежом применом методе савијања гредица у четири тачке / Determining of the fatigue resistance of a grid-reinforced asphalt concrete by using four point bending beam test
(Srpsko društvo za puteve VIA VITASerbian society for roads VIA VITA, 2018)
Флексибилне коловозне конструкције су подложне појави пукотина услед замора и термичких утицаја, а значајан проблем представља и појава рефлектованих пукотина код полукрутих коловозних конструкција или код крутих које су ...
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 ...
