Purpose – The need for more efficient and effective public-private partnership (PPP) projects makes performance management of increasing importance, especially with respect to stakeholder expectations. This paper seeks examine the use key performances indicators (KPI) based on analysis critical success factors (CSF) monitoring PPP transport from perspective different stakeholders. Design/methodology/approach list stakeholders’ objectives including CSF was defined using brainstorming...
Abstract This recommendation is based on the results of an inter-laboratory study organised by RILEM technical committee TC 264-RAP "Asphalt Pavement Recycling"—Task Group 3 (TG3) focusing Asphalt Binder for Recycled Mixture. The TG3 aimed to evaluate effect a specific family materials known as asphalt recycling agent (ARA) aged binder under different configurations. Even though ageing irreversible phenomenon, effective ARA must have capability improve flexibility bituminous and their...
In order to preserve natural resources, the use of waste and alternative materials in construction maintenance roads is increasingly investigated. This paper presents results testing wearing course asphalt mixtures (AC 11s SURF 50/70) made with various percentages fly ash, used as a partial or complete substitute for mineral filler. The properties ash were determined assess their suitability mixtures. experimental research was performed on samples containing from three different sources,...
The need for road (re)construction materials is constantly growing. At the same time, there a limited quantity of new, high-quality available and buildup secondary/recycled construction materials. One possible solution may be use recycled concrete aggregate (RCA) in asphalt mixtures instead natural (NA), which also promotes economic environmental sustainability. potential fine coarse RCA analyzed this work. Nine were tested base course layers, where was used as NA substitute. impact (up to...
This paper presents the development of prediction models for unit costs road works that could be applied to strategic planning at network level. A specialized data set was used, which generated under a World Bank study included 200 work contracts from 14 countries in Europe and Central Asia (ECA) signed between 2000 2010. Two techniques were used model development: multiple regression analysis artificial neural networks. Classification trees as an intermediate step evaluate correctness...
The use of freeform (sculptured) surfaces in the product design process is accelerating at an exponential rate driven by functional as well esthetics demands. CAD/CAM software a must their and manufacture. While geometric aspects are relatively wellcovered, issues still remain when it comes to actual manufacture surfaces. major related generation proper toolpaths that would assure required surface quality, minimization total maching time, control magnitude cutting forces, etc. This paper...
The investigation of the influence acid/base treatment and addition level non‐metallic fractions (NMFs), obtained by processing printed circuit boards, on mechanical properties shrinkage unsaturated polyester resin (UPR)‐based composites was main topic presented in this paper. NMF particles were treated using four different oxidative/etching agents: H 2 SO 4 /KMnO (NMF1), /HNO 3 (NMF2), HNO (NMF3), NaOH (NMF4). Treated NMF(1–4) characterized fourier transform infrared, Boehm titration,...
Private participation in roads revived strongly transition and developing countries between 2005 2008, growing during the period from US$6.2 billion to US$16.4 a year, new historic peak. However, view of recent global financial crisis, there has been some retraction private financing resulting an investment US$15.8 2009. Driving policy-makers' renewed interest attracting for is need greater investments keep road networks acceptable condition carry out social economic expansion plans context...
This paper presents new methodology for determining the actual stress–strain diagram based on analytical equations, in combination with numerical and experimental data. The first step was to use 3D digital image correlation (DIC) estimate true by replacing common expression contraction measured values. Next stress concentration using a methodology, recently introduced expressions verification finite element method (FEM), obtain diagrams, as named this paper. essence of is introduce factor...
Over the last couple of decades there has been an increased contribution private sector to finance infrastructure projects. However, in view current global financial crisis, it become more difficult for governments, particularly transition and developing economies, attract financing infrastructure, which may affect negatively capacity many countries expand, even keep up their infrastructure. While this is observed short-term phenomenon, still not clear what will be medium long term effect...
This study aims to assess the feasibility of using copper slag (CS) in asphalt mixtures both surface and base layers road pavements. For this purpose, two sets with different CS content (15 30%) fraction sizes (0/8 0/16 mm) were prepared. The optimal binder each mixture was determined Marshall mix design method. Their laboratory performances investigated compared properties reference mixtures, i.e. consisting exclusively virgin materials. Test results showed that adding for layer improved...
Estimating the variability of key pavement design inputs is essential to reliability-based design. The thickness most layers has a great impact on outcome practically all analyses performance. within-section layer investigated here, as extent mean deviation from its thickness. Pavement data (elevation and core measurements) large number newly constructed flexible rigid sections in Long-Term Performance (LTPP) program were examined. To determine distribution type data, combined statistical...
Application of appropriate preventive maintenance treatments, at the right time, extends service life pavements, resulting in benefits to road users through increased ride comfort and safety agencies reduction future costs improvement network condition. Preventive treatments usually have been applied on highly trafficked sections Serbian national network, but they not low-volume part network. This study used roads as a case identify for roads, model these into pavement management system,...
In transport infrastructure concessions, the sources of revenue to private partner (or concessionaire) may include (i) users (e.g., landing fees, in case airports), (ii) government (e.g. through availability payments), and (iii) both government, which might be called a hybrid concession. An example latter is highway concession where concessionaire charges tolls road but, because relatively low revenues, agency complements toll with payments. Focusing on airports, this paper summarizes cases...
The National Park Service Road Inventory Program (RIP) uses automated collection and processing of pavement-condition data. study examines various approaches to quality assurance (QA) sampling used evaluate those RIP includes roadside-inventory-feature data at 258 national parks, covering over 5,000 mi paved roads. Evaluating the some elements requires manual assessment conducted by trained analysts. Because high volume collected processed data, it is economically impractical check all...
The World Bank Highway Development and Management (HDM-4) tool has been used extensively for the management of road networks, particularly in developing countries. paper describes application HDM-4 model local roads Bosnia Herzegovina (BiH), Herzegovina-Neretva Canton (HNC). study was performed with aim to define works program investment priorities by analyzing impacts different budgets on future network condition. 396 km-long HNC consists 13 that are either graveled or paved. A large part...
