The use of controlled frequency vibration (CFV) technology and its applications in construction continue to grow - *Paul Jaworski Controlled frequency vibration (CFV) technology has been around since the mid-1990s for concrete pavement applications. The technology has seen a gradual increase in acceptance, particularly in certain applications. For the 0-37mm (1.5”) slump pavement mix designs, many contractors were experiencing material separation due to speeds over 8,000vibrations/minute (VPM). With the wi

SunWest Construction Development Corporation has been using a concrete paver from Power Pavers at the new Bicol International Airport in the Philippines. The machine has been used to pave a runway, taxiways, and aprons for the US$105 million project underway in the Daraga municipality of Albay province in the Bicol Region. The new facility has been built as a replacement to the single runway Legazpi airport, which is located in an urban area where future expansion is not possible. SunWest used its Powe
