Ammann has successfully completed the design and installation of a custom-built 1000-ton ready-mix silo at Asfalttikallio’s asphalt plant in Tuusula, Finland. The project, including a high-efficiency double skip system, significantly increases the customer’s storage capacity, improves operational flexibility, and supports more sustainable asphalt production.
This latest collaboration between Ammann and Asfalttikallio reflects a shared commitment to innovative solutions that meet today’s productivity demands while aligning with long-term environmental goals.
The new 1000-ton silo complements an existing 800-ton storage unit at the Tuusula plant, more than doubling the facility’s total silo capacity. With this expansion, Asfalttikallio can better manage peak production periods, store larger volumes of mix in advance, and respond quickly to shifting project demands or sudden weather changes.
“Ammann worked closely with us to understand our plant layout, production goals, and day-to-day operational needs,” says Arho Pylkkanen from Asfalttikallio. “The result is a solution that not only expands our capacity, but also enhances the speed and quality of our output.”
A key feature of the new installation is Ammann’s double skip solution, developed to eliminate potential delays caused by skip travel time from the mixer to the silos. By operating two skips, material can be transported efficiently, ensuring uninterrupted production and reducing the risk of bottlenecks—particularly during high-output periods.
The new setup also gives operators more control and flexibility when managing different asphalt recipes, allowing seamless switching between storage silos based on project requirements.
Ammann’s solution goes beyond production efficiency. It’s also designed to support Asfalttikallio’s sustainability objectives by reducing energy consumption, minimising waste, and optimising resource use. The added storage enables longer production runs and fewer start-stop cycles, which in turn reduces fuel consumption and equipment wear.
The modern as1 control system, intelligent loading, and improved thermal insulation all contribute to a more efficient and eco-friendly operation—aligning with the long-term vision of building sustainable infrastructure for future generations.
The success of the Tuusula silo expansion is also a reflection of the strong and trusted partnership between Asfalttikallio and Ammann. Both companies share a deep commitment to innovation, technical excellence, and sustainable development. Ammann’s expertise in custom-engineering solutions for modern asphalt production plants was key to delivering a project that not only met but exceeded expectations.
“We are proud to work with Ammann, who consistently understands our goals and operational realities,” Arho Pylkkanen adds. “Together, we’ve created a setup that’s not only technically advanced but also scalable and future-proof.”
With this project, Ammann once again demonstrates its ability to deliver scalable, high-performance solutions that meet the evolving needs of asphalt producers. By combining advanced technology with local expertise and customer collaboration, Ammann continues to help clients build smarter, more sustainable infrastructure across the globe.
