The contractor TSM building the high-speed Russian motorway ‘the M11’ is relying on a mobile concrete-mixing plant ‘CBT 60 SL Elba’ that offers speed when it comes to relocation.
“We acquired the CBT 60 SL Elba because it has several advantages, including its ability to be quickly assembled,” said Dmitry Popov, technical department chief of TSM Company, a leading transportation construction firm with headquarters in Moscow. “Transport is simple, and assembly times are short. The plant’s electric and pneumatic components are completely pre-installed. Also, no foundations are needed. Soil compacted to 250 kN/m2 is sufficient.”
The M11, also known as the Moscow-Saint Petersburg motorway, is a significant undertaking. It runs parallel to the existing M10, but will be a high-speed tollway with an average travel speed of 150 km/h. When completed in 2018 it will be 650 km long, with the number of lanes ranging from four to 10. It includes 32 interchanges, 167 overpasses and 85 bridges.
TSM, founded in 2005, is working on the phase of the roadway that stretches from kilometres 58 to 149. Providing ready-mix concrete for that length of road will require plant relocation. The plant also will be deployed to other projects after the motorway is completed. “We call this plant ‘super mobile,’” said Popov. “CBT 60 SL Elba is extremely fast in set-up times due to its folding mechanisms and compact plant design. It needs just two open-top containers for relocation. It also has favorable transport dimensions and consistently complies with requirements.
The plant’s primary role on the M11 is producing ready-mix concrete and hard mixes for exits from bridges and overpasses. Besides mobility, the plant also provides the productivity needed to meet deadlines, with a potential output capacity of 58 m3 per hour.
“The cycle time is short because of direct weighing of inert material on the belt conveyor and direct feeding into the skip,” Popov said. Mixing quality also is good, ensuring homogenous material production.
More work awaits the CBT 60 SL Elba after the M11. “Our company is engaged in complex construction, reconstruction and repair of highways, airfields and industrial and hydrotechnic facilities,” Popov said. “The plant will be relocated frequently. It will mainly work on the construction of bridges, flyovers and roads.”
TSM has a long history of landing high-profile projects, including work on the M4, M9 (Baltic Highway) and A-149 Adler to Krasnaya Polyana Highway. Work on a variety of airfields has been completed as well.
TSM believes that advanced technology and innovation enable it to respond quickly to the needs of its customers – and to gain competitive advantages. It offers comprehensive infrastructure construction through its more than 2,200 units of equipment. TSM produces its own mixes and minerals and operates a modern maintenance and repair facility and certified laboratory.
“We rely on technology to help us deliver quality results to our customers,” Popov said. “The CBT 60 SL Elba plant fits well with our commitment to keeping projects on track through technology and productivity.”
