Previously adopted planning documents and conclusions of the City’s Expert Team provided a stronghold for these activities, while positive experiences influenced the commitment to continue with similar activities in the future. In order to answer this question in a quality way, it is necessary to lay down strategic foundations for the systemic arrangement of intersections on the primary network of the City. The paper presents initial research regarding the definition of potential locations for the application of this type of intersections in the Banja Luka urban area as a basis for a strategic development document, i.e. an urban plan.

Road organizations throughout the world are addressing these challenges in different ways. The paper presents results of the institutional assessment conducted with the main purpose to evaluate the adequacy of the public sector to manage and perform maintenance activities, and introduce performance based maintenance contracts into practice, and to suggest improvements where it is established that they are needed.

Continuous expansion occurs spontaneously because people settled mainly in places that could provide them with certain resources for survival and life. With the development of settlements over a period, the necessary traffic also developed. One cannot imagine the functioning of one without the other, so one concludes that settlements and traffic are closely connected. The paper defines, through consideration of the development of smaller settlements and the traffic that serves them, what should be fixed, to eliminate or mitigate the weak points in the further development of settlements and traffic in the Balkans, while also talking into consideration their sustainability.

Svi ti materijali se nalaze oko nas, ali ih je potrebno na pravi način iskoristiti, što pretpostavlja i poznavanje njihovih svojstava i predviđanje ponašanja u gotovim konstrukcijama. U Bosni i Hercegovini postoji dovoljno kapaciteta za dobijanje kamenih agregata radi proizvodnje svih slojeva kolovoznih konstrukcija. U radu se prikazuje procedura i definišu osnovna ispitivanja stenskih materijala kako bi se dokazala njihova upotrebljivost za izgradnju kolovoznih konstrukcija u Bosni i Hercegovini. Daje se kratak osvrt na osnovne geološke karakteristike ovog prostora, te navode i opisuju kamenolomi najvećeg kapaciteta. Glavni cilj rada je da se utvrdi da li su materijali koji se mogu eksploatisati na prostoru Bosne i Hercegovine dovoljno kvalitetni da bi se koristili za građenje kolovoznih konstrukcija, kao i gde i na koji način se isti mogu upotrebiti.

However, although there were concerns about the impact on the environment in the past five decades, it was only in the early 21 st century that the effects of transport on the environment were adequately evaluated through the formulation of transport policies. It is important that a global consensus has been reached on the fact that the impacts of transport infrastructure and transport on the environment are essential. Still, it is far more important for the policies of protecting and improving the environment not to conflict with economic competitiveness so that properly formulated regulation could lead to discoveries and improvements, which would result in a win-win situation for both the public and the manufacturers and the improvement of the credibility of competent institutions and organisations in particular. Through a chronological summary of the transformation, this paper moves from the basic environmental protection toward sustainable development in global and European frameworks, and it emphasises the essential aspects that must be addressed in defining a political and strategic framework for the management of transport infrastructure and transport in underdeveloped and developing countries to meet the requirements for sustainable development.

At the same time, pollution most often occurs in a relatively narrow zone of the construction site, as well as along access roads. For the purpose of completing the highway on the southern and south-eastern branch of Corridor X in the Republic of Serbia, an extensive program of protection and monitoring of various environmental parameters has been made, which, among other things, included soil quality. During the multi-year implementation, a large amount of results was collected on the basis of which it is possible to make certain analyses and conclusions regarding the organization of the contractor’s work, implementation of mitigation measures, as well as the consequences that occurred during the works.

The paper presents an analysis of the existing legislation on critical infrastructure in the Republic of Serbia, as well as performs comparison with the legal practice in the region and the European Union.

The paper presents the possible solution of traffic surfaces that service the entire lot, as well as the landscaping on the free part of the lot.

According to the performed experiments and calculations, different processes of destructive behavior of tunnel lining were simulated in combination with elastic and elastic-plastic behavior of materials taking into account the tunnel loading, the interaction between the fiber reinforced concrete and soil, as well as the interaction between the fiber reinforced concrete and the inner lining of the tunnel.

The temperature stresses which occur in pavement structures include stresses due to bending and buckling, stresses due to friction and hidden stresses. Stresses caused by the influence of temperature in the pavement structure during the day are generally below the strength of the component materials so they do not cause the consequences for structure. However, appearance of residual stresses and their accumulation after a sufficiently long period of time may lead to failure in structure, i.e. thermal fatigue. The paper presents the effects of temperature changes on the pavement structures in the physical and mechanical terms, and the manner in which the temperature is taken into account during the design of pavement structures.

Currently, more than sixty regional units across the country are responsible for the maintenance of the entire road network. These units carry out their duties equally on main, regional and local roads. The modern way of operation of motorways requires a different approach with the specific procedures and regulation of relations for this type of network. Based on existing organization and capacity, as well as institutional changes/strengthening of the Agency for State Roads, it was found that operators from the public sector can provide maintenance of motorways in a certain period. Such a proposal must be accompanied by organizational changes in terms of reduction of existing units through the establishment of specialized regional units for maintenance of motorways that will be responsible for longer sections/sectors of about 200-300 km. This paper presents an analysis of the necessary capacity to maintain the motorway network in Azerbaijan, and estimate of the total costs for setting up new units for maintenance of motorways.

Different methodological approaches were used for that purpose. The objective of each approach, i.e. index, is to characterize contribution of pavement structure and condition to performance of road asset, from the point of two relatively different views, road/pavement engineer vs. road user. Paper describes methodological approach for defining pavement condition mark in relation to these two aspects, through indicators related to surface problems (user aspect) and indicators related to structural problems (technical aspect).
