The Dynapac CP274 pneumatic tyred roller from Atlas Copco Road Construction Equipment offers new features designed to enhance efficiency, serviceability, safety and operator comfort, as well as producing perfect compaction results. The Dynapac CP274 is equipped with a spacious platform with operator-friendly controls, plus a rotating and sideways sliding seat and steering assembly. Available as an option is a comfortable cab that provides outstanding all-round visibility with the added benefit of either air

Sumitomo showcased a new model of its HA60C J-paver2360, equipped with electric heating. The paver heating system is quick to reach the required temperatures from the start, said the company. The design also improves fuel consumption for greater operational efficiency. An LPG heating system is also available. The J-paver screed features variable width range, enabling the machine to pave any width from 2.3m to 6m without the need for any extra extension equipment. The width can be changed during paving witho

A hydrodstatic propel system for smooth control is said to be a key feature of Cat’s new AP300D paver being unveiled at bauma. Described as versatile and manoeuvrable, the AP300D is said to boast paving widths that are easily adjusted with standard hydraulically extendible widths of 1.7m-3.2m, and a 4m maximum width with bolt-on extensions. Using a reduction attachment narrows the paving width to 650mm. Cat’s new paver has a turning radius of 1.65m and fast travel speeds of 16 km/h said to enhance manoeuvra

Roadtec is launching a 2.5m tamper bar screed developed by the firm’s operation in Germany. This screed has been designed as a heavy-duty, high-quality unit. It is designed to suit customer in Europe and in worldwide markets while for US customers, it will be used for RCC applications. Worldwide it will be sold on the new German-built Roadtec asphalt pavers.

TanGO, a new tangential oscillation system, has been launched at bauma 2013 by BOMAG. The company has reassessed many details of the well-established exciter system in terms of both technical and cost-effective aspects, and optimised it in key areas. BOMAG oscillation makes use of the physical laws of vibration generation to best effect. The careful coordination of exciter system to drum weight ratios is the basis for the tangential oscillation. The result is clearly improved power for vibration generation

From mixing plant to compaction, the temperature of asphalt is critical. Cold asphalt can lead to road damages, which result in additional costs of up to 46% due a shorter lifetime of the road. With optimum composition of both asphalt material and process flow being priorities in the road construction process, the new MOBA PAVE-IR temperature scanner system enhances both.

Cat says an Eco-mode facility on its new CB24B and CB34B compactors, being launched at bauma, combines increased engine power availability with lower fuel usage. The CB24B and CB34B meet the European Union (EU) Stage IV/United States (U.S.) EPA Tier 4 Final emission standards. Versions of the C1.5 engine in the CB24B and the C2.2 engine in the CB34B are also available for customers in EU Stage IIIA and US EPA Tier 4 Interim emission standard markets.
