3D machine controls can optimise milling efficiency, Mike Woof reports. More efficient milling and recycling operations can be carried out by using the latest 3D control systems on the market. At the last Trimble Dimensions event in Las Vegas, the advantages of 3D controls for milling operations proved a key topic. The use of 3D control systems can offer huge advantages in milling operations. This technology helps increase productivity as the milling machine will only remove what is required, which also hel

New regulations and technology are driving change in the soil compaction sector - Mike Woof reports. The impact of the Tier 4 Interim/Stage IIIB emissions regulations has been hard on some machine sectors in particular. Sloping engine covers have been introduced in several equipment categories as a way of improving visibility for operators, including soil compaction machines. At the same time, new machine guidance technologies have been developed and introduced to the soil compaction market, boosting produc

A growing niche market for roller compacted concrete has prompted manufacturers to offer solutions. Mike Woof reports. Increased demand for roller compacted concrete (RCC) machines in certain applications mean that this is now a growing market, with manufacturers having developed new machines for this sector. RCC comprises uncrushed and/or crushed aggregate, hydraulic binders and may also contain concrete additives. It is mixed in a concrete mixing plant on or near the job site and one of its main benefits

An array of new models has increased competition in the market for compact asphalt compaction products - Mike Woof reports

The market for concrete pavers continues to fuel research and development into new models writes Mike Woof. The range and breadth of concrete slipforming and paving equipment on the market continues to grow as firms develop new and improved models. Prior to the recent CONEXPO-CON/AGG 2011 construction equipment show in Las Vegas, some of the best known manufacturers had already announced their new and improved slipforming machines. GOMACO, Guntert & Zimmermann, Power Curbers and Wirtgen all had recent or ne
