Compaction equipment from 206 Dynapac is playing a key role in maintaining an important highway link in Brazil. Brazilian contractor Egesa has a contract to maintain the highway connecting the giant Jirau hydroelectric project and the nearest town of Porto Velho in Brazil's Rondônia State. The firm is using a fleet of Dynapac compactors to maintain the 130km stretch of two-lane highway between Porto Velho and Jirau in north-western Brazil. The work is needed as the road is heavily used because of the construction of the huge hydroelectric project on the Madeira River at Jirau. Amongst the machines are a newly acquired Swedish-built CC424HF vibratory compactor and a Brazilian-built CP 274 pneumatic-tyred roller, which are being used in tandem to first compact and then seal the new asphalt surface that is being laid. The BR364 highway runs all the way from the State of Mato Grosso through to the Peruvian border. The contractor is laying an asphalt wearing course directly onto the road surface, the road itself being sound enough for the traffic but subject to exceptionally high wear. The two Dynapac machines, working in tandem, require about six passes to compact the asphalt to its necessary 95% compaction depth.
