Abstract
Multi-attribute analysis is a popular tool in many economical, managerial, constructional etc. problems. This document provides a review of international and national practices in investment decision support tools in bridges and road quality management. Cost benefit analysis and multi-attribute analysis are principal methodologies in supporting decision-making in bridges and road quality management. The complexity of the applications shows significant differences in international practices. There are continuing discussions amongst practitioners and researchers, regarding to which one is more appropriate in supporting decision-making. It is suggested that more than one approach should be regarded as complementary instead of competitive means. Multi-attribute analysis may be particularly helpful in early stages of project development, strategic planning. Cost benefit analysis is used most widely for project prioritization and selecting the final project from a set of alternatives. These methodologies are applicable to the problems with large numbers of scenarios and attributes. The research has concluded that multi-attribute decision-making methods are very useful for bridge and road construction.

The primary focus of this paper is to demonstrate the economic considerations in evaluating alternative road design and construction methods
Summary
Roads and bridges infrastructure assets are drivers of economic development and social equity. The Baltic Journal of Road and Bridge Engineering, 2008, 3(3): 152–160 sets of attributes is an essential part of the decision-making processes especially in the domain of infrastructure projects. The system is developed for the formation of maintenance strategies with/without annual budget limitations This system is based on life-cycle cost analysis of an entire bridge inventory, which comprises part of a highway network. The research work involves evaluating the technical and economic feasibility of undertaking alternative road construction techniques. With an ability to predict the whole life-cycle performance on the basis of future maintenance treatments, road managers can more reliably assess alternative surfacing and structural preservation strategies. Authors used the above-listed tools to model the processes of assembly of structural corrugated steel plate structures They are used for constructing small bridges, culverts as well as pedestrian and vehicle underpasses. Researchers presented investigation into dust reduction on gravel roads through the use of bitumen emulsions, calcium chloride, and calcium lignosulfonate
