Rehabilitation Works Of The Existing Asphalt Pavement And Connecting The Existing Asphalt Pavement With The Newly Constructed Pavement, Motorway E-75, Section Tabanovce - Kumanovo From Km 0+764.70 To Km 8+388.43, Part Of The Corridor X

Abstract

The Corridor X is part of the pan-European network of corridors. The starting point of the corridor is in Salzburg, Austria and the end point is in Thessaloniki, Greece. The corridor passes through Austria, Slovenia, Croatia, Serbia, Macedonia and Greece. The Construction of the Corridor is supported by the international financing institutions like the European Bank for Reconstruction and Development (EBRD) and the International Bank for Reconstruction and Development (IBRD). The paper refers to one of the sections in R. Macedonia that is under the construction, section between Tabanovce and Kumanovo in length of 7.62 km.Part of the pavement works consisted of rehabilitation of the existing pavement with applying polymer grids, specially designed for such purpose. In the paper the entire procedure of the pavement design will be presented, with particular attention on the quality requirements of the materials that should be for the road construction. Numerical analysis of the pavement was accomplished using the software package PLAXIS. The results of these analyses are presented in the paper, namely: stress fields and zones where the plasticity limit of the materials was reached. The cross section was treated with and without polymer grids. The number of the polymer grids in the cross section was also varied, as well as its location. The presented procedure of the pavement design could
