Recycling

Trimble is offering a new version of its Trimble GCS900 grade control system designed for use with milling machines. The new package allows contractors using planers for road repairs to achieve material savings and increased road smoothness during the ensuing paving operation. By controlling the cutting depth of a milling machine accurately, a contractor is less likely to make an overcut in the areas being repaired and as a result, is less likely to require additional asphalt or concrete when paving the new

Automatic 3D machine guidance is a highly sophisticated area and a high level of expertise is often required to ensure applications of the advanced technologies work as desired. Fugro is a specialist firm that has gained experience using 3D guidance tools over many years and for certain tricky projects, Hexagon, the parent of Leica Geosystems, has turned to Fugro for assistance. For one difficult job in particular, Fugro's specialists were brought in at the request of an Icelandic contractor. The project ca

Carlos Jofré, technical director of the Spanish Institute of Cement and its Applications (IECA), introduces, on behalf of EUPAVE*, a sustainable technique to rehabilitate fatigued pavements Recycling of pavements is a technique whereby an existing degraded pavement is modified and transformed into a homogeneous structure that can support the traffic requirements. More specifically, it involves reusing the materials from the existing pavement for the construction of a new layer, including the pulverisation o

Cape Town's N2 is a strategic South African highway that connects the port city with the country's southwestern region. Due to increasingly heavy traffic on the highway, it was in need of an upgrade, and fast. So one of Cape Town's largest contractors, Vusela, was awarded the government contract to remove the asphalt layers and stabilise the sub-base to strengthen the road's load capacity in preparation for resurfacing.

Milling techniques remain one of the most widely used recycling methods Well-proven, cold milling techniques remain one of the most widely used methods for materials recycling in road construction. Milled road materials can be cleaned up and re-used in both asphalt and concrete highway construction. German firm Wirtgen has long dominated the market for road milling machines and has the largest share of the sector (as well as the broadest product range), although other firms based in Europe and the US are be

Plate Locks is described as a cost effective and reusable road plate securing system said to be an alternative to cold patch asphalting. The system fastens to the road, preventing any sliding and shifting of the plate. Made from a recyclable, safety orange polypropylene thermoplastic, Plate Locks come in 1.52metre lengths and are said to be adjustable to fit any sized plate or configuration of multiple plates. This, coupled with being easily transferable from job to job, is said to allow the product to pay

The new Road Razor ECO Pro is said by its US manufactuer Kennametal to combine a groundbreaking and proprietary shape with improved hardness throughout the head area and a thicker nonagon-shaped washer. The company says its characteristics make it the economical and ecological tool of choice for road-milling companies interested in improved performance and maximum value.

German firm Wirtgen is retaining its lead in road recycling technologies – Mike Woof writes Tests on cold recycling with a new layer thickness using Wirtgen's sophisticated WR 4200 machine have shown impressive results according to the firm. The road construction and traffic authority Landesbetrieb Mobilität (LBM) Cochem-Koblenz commissioned a pilot project as part of its plan to optimise the cold in-place recycling process (CIR). The aim was to examine the extent to which the layer thickness can be reduced
