Public Enterprise for State Roads, Macedonia
1.
General Data
Тhe section Kumanovo – Miladinovci is part of the motorway A1 (Trans - European
Transport Corridor X). The right carriageway of this section spreads between the starting
chainage point on km 8+388.43 and end point at km 30+765. Its full length is 22,38km. The
right carriageway of the Kumanovo – Miladinovci motorway section is the one for the driving
direction from Kumanovo to Miladinovci.
The starting point of this section is at the end of Tabanovce – Kumanovo motorway section
constructed in 2011. The end point of the section is at the beginning of the concrete
pavement on the Pay toll “Miladinovci”.
The design for rehabilitation of the motorway section Kumanovo – Miladinovci (right
carriageway) was prepared in the year 2014 by the design company “GEING Krebs Und
Kifer International and others” – Skopje. This documentation contains technical solution for
the pavement rehabilitation and technical measures for reparation of the structures (bridges,
culverts etc) on this section. Design documents are available in Macedonian and English
language.
The replacement of traffic signs and pavement markings is planned to be performed
according to the design prepared by “Zebra Proekt” – Skopje in year 2010, available only in
Macedonian language.
The Technical Audit of all design documents was done by the Civil Engineering Faculty –
Skopje.
2.
Scope of the Works
The scope of this project is rehabilitation of the right carriageway of the motorway section
Kumanovo - Miladinovci. The actual length of rehabilitation works on the right carriageway,
subject to this operation, is 22,38km.
The rehabilitation will be done on the existing carriageway and on the access ramps on the
existing interchanges, without occupation of additional land or building additional
interchanges, connections, structures etc.
In general, the rehabilitation of the section Kumanovo - Miladinovci (right carriageway) will
be conducted in accordance with the current regulations and national legislation for such
kind of works (Law on Construction, Law on Public Roads, Law on Safety of the Road
Traffic, etc.), as well as bidding terms and prescribed technical requirements.
