Asphalt milling, paving & compaction

A professional drag race takes only a few seconds. But in these brief moments, everything – including the track surface – must be absolutely perfect. Apart from having excellent grip, the track must also be completely even. So, when Stange Asfalt was rehabilitating the Gardermoen Raceway near Oslo - Norway’s only permanent dragstrip – the company used state-of-the-art equipment supplied by VÖGELE and Hamm. On the dragstrip, the drivers accelerate up to top speeds of more than 500kph within seconds. After

Milling efficiently with a versatile, mid-sized machine has offered benefits on a German road job. A German contractor has found that using a mid-sized milling machine from Wirtgen has offered a good combination of both versatility and productivity for a road rebuild job. Kassel-based milling specialist VORO has used a Wirtgen W 100 CFi to upgrade the surface of a section of the busy B3 route. The B3 is an important route and runs 755km from Buxtehude in the north of Germany through to the Swiss border in t

Infrastructure services company FM Conway has won two highways services contracts by the London Borough of Newham worth up to £40 million over four years. The two contracts cover highway maintenance and roads improvement schemes for Newham’s 419km of streets, including surfacing, civil engineering services, specialist road marking and drainage support. The new contracts build on the existing 10-year partnership.

Real time information on asphalt density and uniformity can boost construction quality - *Roger Roberts, GSSI. Properly compacted asphalt is a major factor in the lifespan of a road, as inadequately compacted asphalt deteriorates at a more rapid rate than properly compacted material. With the billions spent on road construction and repairs each year, it has become a matter of urgency to find new technologies that can ensure the integrity of asphalt on newly paved roads. New radio wave technology is now avai

GSSI's new PaveScan unit can provide accurate real-time measurements and uncover problems that occur during the paving process, including poor uniformity and significant variations in density. By avoiding these problems, PaveScan RDM helps avoid premature failures from road ravelling, cracking, and deterioration along joints. PaveScan automatically measures the dielectric value to identify anomalies in real-time. In addition, the dielectric values can be used to as a means to correlate voids and density in

Huesker says that its new Tektoseal Active product family offers safe long-term containment of contaminants. Relocating contaminated soils can be unfeasible or undesirable so preventing contaminant migration to unpolluted areas requires solutions that are readily adaptable to specific site conditions. The firm now offers three new products – Tektoseal Active AS, AC and CP – for contaminated site remediation, groundwater protection and oil absorption. Active Geo- Composites comprise three permanently bonded

Ammann has provided CONEXPO-CON/AGG 2017 with the first fully-assembled asphalt mixing plant in the trade show’s history. The plant, an ABA UniBatch, stands at a height of nearly 27m. It is a key product for Ammann as it enters the North American asphalt plant market.

Early detection of pavement defects and the causes of deterioration is essential for effective maintenance planning, writes Dr Alena Uus* There is a need for optimisation and development of UK highway survey methods that would provide comprehensive information on the surface and subsurface pavement condition and operate at traffic speed, which eliminates the requirement for lane closures. Performance of non-destructive testing (NDT) methods commonly employed in pavement condition surveys can be potent

A Stress Absorbing Membrane Interlayer is delivering stronger, safer and more reliable surfaces for the UK’s M3 Smart Motorways project in the southern England.
