A fleet of four new Dynapac single drum vibratory rollers is currently working on the massive Alkumru Dam for the Hydro Electrical Power Plant project in Turkey. A total of 18 million m3 of clay and rockfill is being compacted to form a finished structure with a height of 134 m from foundation level and a crest length of 909 m. The $500 million project, which currently employs a total workforce of some 1250 people, is being undertaken by Limak HES Yatirimlari AS, one of the region's leading investors in the power industry. The Alkumru Dam is one of seven adjacent dams to be constructed on Botan Brook, a tributary of the River Dicle, and once completed at the end of 2010, will transform the region into one of large lakes providing much needed electricity. Since the project commenced in 2007, Dynapac, part of the Atlas Copco Group, has been able to demonstrate not only its ability to supply the ideal soil compaction equipment for the application but also provided the necessary follow-up expertise to ensure its correct and efficient use. The rollers chosen for this project consist of three CA512D smooth drum machines and one CA512PD padfoot version, all with a drum width of 2130 mm. The smooth drum units are being used for compacting layers of rockfill whilst the padfoot machine is working on the cohesive clay areas. The machines are making three or four passes of up to 200 m in length achieving the required 99% degree of compaction, much to the satisfaction of project manager Sukru Sevim. According to Limak's machinery manager Ali Sabahci, “Out of the 240 or so pieces of large equipment on site, the Dynapac rollers are among the most important as they are undertaking the critical compaction of the impermeable clay layers and maintaining proper contact points between the clay and existing rock layers in the dam toe and valley.” Once completed, the Alkumru Dam and the Hydro Electrical Power Plant is planned to produce 828 million kWh of electric power per annum with its 265 MW installed capacity fulfilling part of the Turkish Government's long-term plan to reduce the country's dependence on foreign power.

Dynapac Compactors Chosen for Key Role on Major Dam Project in Turkey
This commitment to its customers recently involved a visit to the important Alkumru project by a group of four key Dynapac and Atlas Copco personnel, including the compaction and paving research manager from the company's International High Competence Centre. During this visit a technical seminar was given to the entire site management and application team covering the latest developments in compaction technology.
