EVALUATION OF ROUGHNESS OF PAVEMENT SURFACE ON SECTION ON CORRIDOR VIII IN REPUBLIC OF MACEDONIA

Abstract

The surface characteristics of the driving surface, impose the level of the driving as one of the main indicators for usability of the driving surfaces, from the aspect of fast, safe and refined transport. Within the experimental part, we analyzed the manner and causes of creation, the influence, criteria and methods for measuring the longitudinal roughness of the driving area in the highway sections, as well as the evaluation of the condition of the driving surface. The results of the analysis and the evaluation of the driving surfaces so far confirmed that the level of the driving surface is one of the most important parameter for its condition. Experience in the world suggests that the setting of roughness criteria - the IRI index, contributed for better design solutions and technological advancement in road construction, resulting in a higher level of evenness on the driving surfaces.
