The new Terex/Cedarapids CR500 Series mainline pavers from Terex Roadbuilding feature a new Cummins diesel engine that boosts power ratings to 260 hp while meeting stringent Tier 3, C.A.R.B. Tier 3 and Stage IIIA emissions standards. The six-cylinder, 24-valve engine varies the fuel stream to use only the amount of fuel needed, resulting in a significantly quieter engine for improved operator comfort. Increased power enables the new pavers to more efficiently handle full-width paving applications and delivers the required power to keep electric screeds at operating temperatures while roading.
