Economic assessment of pavement maintenance and strengthening techniques in view of implementation cost

Abstract

Road and pavement maintenance affect directly traffic safety and comfort. At the same time, maintenance treatments cause traffic discomfort and absorb valuable resources, thus, the choice of maintenance and rehabilitation technique is a complex, yet crucial issue. Road operators need to seek for the financial prerequisites for the success of maintenance strategy. Subsequently, the expected economic benefits will be inextricably linked to road performance features. The study herewith presented enlightens the economic aspect of mainly used pavement maintenance techniques, so as road operators identify the preferred one as regards budget needs. A comprehensive method to evaluate the current maintenance and strengthening techniques for flexible pavements using economic assessment tools is the main task of this paper. The results are meant to be a useful tool for road operators to conclude to the preferable, in terms of financial needs, alternative for maintenance and strengthening works.
