AHP as a Method Supporting the Decision-Making Process in the Choice of Road Building Technology

The article presents a choice of road building technology using the AHP method and the Hellwig method. Based on the analyses carried out with the use of the Saaty and Hellwig methods it was found that the achieved values of ranking for asphalt and concrete pavements are close to each other, which may indicate that both technologies are comparable within the criterions taken for analyses in relation to accepted technological-technical and usability features. When choosing the road building technology one shouldn’t be limited to building costs alone. It’s necessary to consider the costs of 30–40 year exploitation and maintenance of the road. The main task when choosing the road building technology is to build the road of a quality that will enable many years of its exploitation. Based on the analyses carried out with the use of the Hellwig and AHP methods it can be assumed that both technologies. the asphalt one and the concrete one can be competitive because it leads to the progress and development of both of them. Considering the increasing growth of traffic, concrete may be perceived as a technical and economic alternative in comparison to asphalt pavement; which is confirmed in the presented analyses.
