Roadtec has introduced the new heavy-duty steel track RP-2505 paver at bauma 2013. The model on display features high-density screeds with a twin tamper bar screed, which was developed and manufactured in Germany.

Doosan Portable Power is offering its new large 25/280 portable compressor, which meets Stage IIIB/Tier 4 Interim emission regulations. The 25/280 portable compressor has a free air delivery of 28.3m³/min at a rated operating pressure of 25.1bar. Dual pressure regulation is a standard feature of the 25/280 compressor, allowing it to supply compressed air at operating pressures of both 25.1 or 17.2 bar. Dual pressure regulation expands the scope of applications for the 25/280 compressor which includes poweri

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

Massenza has been exporting its innovative technology and advanced construction equipment concepts for over 50 years. The firm manufactures and supplies bitumen handling equipment, such as polymer modified bitumen plants, bitumen emulsions plants, spraying tank, bitumen drums melting units, and hot oil heaters. It also specialises in concrete pavers, canal lining machines, and slipform pavers. Through its extensive industry knowledge, built up through uninterrupted research and field experience, Massenza sa

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.

After two years of research and development, attachment manufacturer Simex has launched the VSE 40, a screening bucket with a patented mechanism that allows the operator to change the size of the screened material from the cab at the touch of a button. All similar products require eight to 10 hours’ work to change the setting, according to Simex’s assistant general manager Fereico Tamburri. “After we introduced our crushing bucket, we visited lots of crushing sites and found out that for all the screening b

Ammann has launched a new infra-red controlled trench roller at bauma 2013. The new Rammax 1575 CI trench roller is the articulated counterpart to the proven, skid-steered Rammax 1515 trench roller. Its launch underscores Ammann’s position as a specialist for trench rollers and rounds off the world's most comprehensive programme by offering both steering concepts.

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

The new range of BOMAG light tandem rollers is a first for the compaction sector. Using the BOMAG Economizer feature, the company becomes the first manufacturer to offer the roller operator a reliable instrument to indicate compaction progress. From the operator’s perspective it is no longer just a ‘feeling’ which determines the quality during the compaction process. Now, with the Economizer, the compaction status is continually displayed and soft spots identified. Until now, assessing the compaction statu

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.
