AB  - Pavement management systems tend to lead to sound decision making regarding the optimal maintenance strategy which is, in most cases, based on the achievement of minimal total society costs which are defined as the sum of user cost and road agency cost. In the last several years, in addition to the user cost related to the costs of gasoline or diesel fuel, motor oil, spare parts, pneumatics, costs related to travel time and accidents, costs related to environmental impacts have been also considered as significant contributors to overall costs. The objective of this paper is to present a model that integrates Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCCA), on a network level. The model has been applied on the national road network of Serbia. The results show how this integrated approach leads to more sound decision making compared with current state of practice.

AB  - About 20% of the Serbian national road network has sections with low volume traffic. These sections are maintained in relatively poor condition since the maintenance budget is typically allocated to the road sections with most traffic. This paper aims to define the appropriate maintenance policy for keeping these sections in "optimal" condition. The traditional approach has been to consider as optimal the condition leading to the minimum sum of road agency costs and road user costs. However, currently there is an emphasis on including environmental cost (greenhouse gas emissions, in particular) into pavement management systems. This extends the concept of optimum by defining it as the maintenance policy leading to the minimum sum of (a) road agency costs, (b) road user costs, and (c) the cost to society of CO2 emissions. Three potential influencing factors are further analyzed: traffic loading, pavement structural number, and the initial condition of the road section. The World Bank's Road Network Evaluation Tools (RONET) model was used to analyze the Serbian low volume road network and develop the optimal maintenance policy. The results show that the cost of CO2 emissions plays an important role in calculating the optimal policy, but unlike the high volume parts of the road network, in the case of low volume roads, a substantial part of total emissions is related to the production and placement of new pavement layers, rather than from vehicle emissions.

AB  - 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 various funding arrangements and life cycle phases, all extracted from the Horizon 2020 BENEFIT project cases database. The project setting is described through a specific combination of project features and/or values of developed indicators. The analysis was applied to identify factors that contributed to projects' performance regarding the resilience to the global financial crisis of 2007-2008. By doing this, it became possible to determine potential liabilities of projects that are already in their implementation or use phases. The analysis showed there are equally strong contributors to a project's success within country-specific, as well as project-specific features. In order to boost resilience toward sudden and unpredicted disruptions, several factors have emerged, such as long term planning, investing in top priority projects (preferably medium size investments), with realistic traffic projections and experienced and responsible concessionaires, but also having in place strong regulatory bodies and government support. The identified mechanism of enhancing the resilience to crisis caused by a specific project setting can be beneficial to multiple stakeholders.

AB  - In addition to their attempt to keep overall maintenance costs low while keeping their road networks in the appropriate condition, road agencies are facing even more demanding challenges as they incorporate effects on global climate change and other environmental impacts into their decision-making process. Many studies and research initiatives have shown the impact of pavement condition on vehicle fuel consumption and maintenance costs, indicating that maintaining the pavement network at the lowest roughness level would lower fuel and parts consumption, which is beneficial for the environment. On the other hand, the more intensive pavement maintenance, which is required to keep roads as smooth as possible, is accompanied significant emissions and negative environmental impacts. The objective of this paper is to find an optimal maintenance plan at network level that minimizes the environmental impact during the entire pavement life-cycle, which includes both traffic and maintenance works.

AB  - 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 through the reduction of future maintenance costs and improvement of the network condition. Preventive maintenance treatments usually have been applied on the highly trafficked sections of the Serbian national road network, but they have not been applied on the low-volume part of the network. This study used the Serbian low-volume roads network as a case study to identify appropriate preventive maintenance treatments for low-volume roads, model these into a pavement management system, and assess the potential benefits of their application compared with the current practice. The World Bank's RONET (road network evaluation tools) model, designed to assess the current characteristics of road networks and their future performance according to various levels of interventions (and budgets), was selected for this study. The model was modified for the study to incorporate use of preventive maintenance treatments. Modifications included adjustment of the pavement deterioration curves to incorporate a slower deterioration rate resulting from the application of crack sealing and pothole patching and surface dressings or thin overlays while the pavement was still in good condition. The results indicate that the use of preventive maintenance treatments would result in increased net benefits and a substantial reduction in future road agency costs compared with the maintenance scenario without preventive maintenance.

AB  - This paper presents the development of prediction models for the unit costs of road works that could be applied to strategic planning of road works at the network level. A specialized data set was used, which was generated under a World Bank study that included 200 road work contracts from 14 countries in Europe and Central Asia (ECA) and signed between 2000 and 2010. Two techniques were used for model development: multiple regression analysis and artificial neural networks. Classification trees were used as an intermediate step to evaluate the correctness of the selected parameters. A total of 19 variables, divided into three groups (oil-price related, country-related, and project-related variables), were tested for their influence on unit cost of asphalt concrete (AC) and road rehabilitation and reconstruction (RRR) costs. The analysis results showed that the level of corruption and the economic environment in a country have a significant effect on both costs of AC and RRR. The resulting models could be particularly useful for the planning and optimization of work on road networks in ECA countries. However, the approach and methodology used for model developments may be applied generally.

AB  - Maintenance of existing road network represents a challenge for public road authorities who seek a balance between available budgets and the need for maintaining level of service at a satisfactory level on existing road sections. For this reason, prediction of cost for road rehabilitation and reconstruction works represents one of key inputs for the objective analysis of projects and available budgets and optimization of road maintenance alternatives. However, the average unit costs of road rehabilitation and reconstruction vary substantially between countries, and even between projects in the same country, due to a number of factors. In this paper an effort is made to develop a prediction model that could be applied for a wide range of conditions in different countries. A specialized dataset is used, which was generated under a World Bank study fora sample of road works contracts from 14 countries in Europe and Central Asia, signed between the years 2000 and 2010. The data sample for the analysis covers 94 projects of rehabilitation and reconstruction of flexible pavements. A multivariate regression analysis is used to evaluate the determinants of the cost per kilometer of the road rehabilitation or reconstruction. The explanatory variables that are tested in the model are divided in three groups: a Variables related to oil prices b Variables that are country specific c Variables that are project specific The variables included in the analyses were chosen in view of their potential explanatory power. The resulting regression model is expected to be useful in the strategic analysis of road networks, including the optimization of road maintenance alternatives.

abstract = "Maintenance of existing road network represents a challenge for public road authorities who seek a balance between available budgets and the need for maintaining level of service at a satisfactory level on existing road sections. For this reason, prediction of cost for road rehabilitation and reconstruction works represents one of key inputs for the objective analysis of projects and available budgets and optimization of road maintenance alternatives. However, the average unit costs of road rehabilitation and reconstruction vary substantially between countries, and even between projects in the same country, due to a number of factors. In this paper an effort is made to develop a prediction model that could be applied for a wide range of conditions in different countries. A specialized dataset is used, which was generated under a World Bank study fora sample of road works contracts from 14 countries in Europe and Central Asia, signed between the years 2000 and 2010. The data sample for the analysis covers 94 projects of rehabilitation and reconstruction of flexible pavements. A multivariate regression analysis is used to evaluate the determinants of the cost per kilometer of the road rehabilitation or reconstruction. The explanatory variables that are tested in the model are divided in three groups: a Variables related to oil prices b Variables that are country specific c Variables that are project specific The variables included in the analyses were chosen in view of their potential explanatory power. The resulting regression model is expected to be useful in the strategic analysis of road networks, including the optimization of road maintenance alternatives.",

AB  - The average unit project cost for road rehabilitation and reconstruction (RRR) works vary substantially across countries and over time, but variation also exists within the country in the same year due to a number of reasons. In this paper an effort is made to develop a prediction model that could be applied for a wide range of conditions in different countries and that could be applied in road maintenance management systems at strategic level and development of road works programs. The resulting model is made of the variables that contribute significantly to the regression. The variables included in the analyses were chosen in view of their potential explanatory power.

AB  - This paper presents the application of the World Bank's Road Network Evaluation Tools (RONET) model to strategic network-level analysis of the Serbian state low-volume road (LVR) network. This network condition deteriorated considerably during the 1990s as a result of the under-financing of its operations and maintenance. In recent years, financing for the road sector has gradually increased and focuses on the most hazardous and highly trafficked parts of the network. However, the overall budget allocated to the sector remains inadequate to maintain the entire state road network in stable condition. The goals of the presented study are to obtain the optimum maintenance and rehabilitation (M&R) strategy and related budget, estimate the impact of different funding levels on future quality, and estimate the economic consequences of budget constraints for the M&R of the LVR network. Application of the RONET model to the prevailing conditions on the Serbian LVR network led to an optimal M&R strategy with a good balance between rehabilitation and periodic and recurrent maintenance. Implementation of the optimal M&R strategy would cause major improvement compared with the current condition of the LVR network. Implementation of higher M&R standards would lead to substantially higher road agency costs and, consequently, lower net benefits, whereas the implementation of lower M&R standards would lead to considerably worse network condition for approximately the same or slightly lower agency costs. This situation means that even minor budget constraints would result in considerably worse network condition and much higher total road transport costs.
