Pre-Feasibility Study for the OOO«DIABAZ COMPOZIT GROUP» of the Tashkent-Samarkand Road Rehabilitation Project / PPP (DBFO / OPRC / BOT) was developed by The Turkish ZeOn Engineering and Consulting in 2021.
The following tasks were implemented :
- Task 1: Alignment Option Study;
- Task 2: Analysis of Feasibility;
- Task 3: Identification of possible PPP Structure;
- Task 4: Assistance to the OOO«DIABAZ COMPOZIT GROUP» to prepare for feasibility study.
The Project will cover about 298 km of the Tashkent – Samarkand Road highway in the Tashkent, Syr-Darya, Jizakkh and in Samarkand provinces.
The start of the alignment of the second section is 0 km, and the end of alignment is 298 km of the road M-39 Tashkent - Samarkand. If the designed road is located along the existing alignment, then it will involve additional land acquisition for construction of 6 - lane carriageway, provision of traffic intersections, which will require demolition of a large number of living accommodations and nonresidential premises, communications etc. Therefore the design envisages bypass of the cities of Sardoba, Gallaaral, Bulungur, at the stretch from Uraitep to Samarkand (interchange in Jambai), at the stretch from Syr- Darya to Ak-Altyn (turning to M-34 and A-373).
In addition, it is planned to build new bridges and overpasses over interchanges and structures, as well as introduce an intelligent transport system.
Design of a road pavement is envisaged in accordance with the requirements of ShNK 2.05.02-07 standard and departmental norms and rules MKN 44-2008 “Instructions for design of rigid road pavements”, approved by the State architectural and construction committee of the Republic of Uzbekistan on 26.12.2008 and approved by “Uzavtoyul” on 31.12.2008.
In accordance with the requirements of ShNK 2.05.02-07 the load on single most loaded axle of a vehicle, for the purpose of calculation of the strength of road pavement, is accepted as 130kN (13tc), and the service life will be 25 years.
During design of the road pavement the meaning and the function of the road were taken into account, along with intensity of traffic, reliability and economic efficiency, provision of local building materials, climatic and soil and hydraulic conditions, and also maintenance and repair condition of the road. As a part of the Project it is envisaged to arrange Hot Mix Asphalt pavement on the carriageway in both directions of traffic. At that, the existing asphalt-concrete pavement will be used as the sub-base. Asphalt concrete laid on cold recycling.
Identification of possible Public-Private Partnership (PPP) Structure was considered as Output and Performance Based Road Contracts (OPRC).
