The AV 120 X asphalt roller is the latest addition to the family of articulated tandem rollers produced by Ammann. Equipped with 1880mm wide drums, the AV 120 X has been produced for efficient compaction on asphalt mixes and binder courses. An unobstructed view of the drum, a sliding and rotating operator’s station and a drive system with two hydraulic pumps is claimed to deliver improved driving and rolling properties. The 11tonne machine is powered by a Cummins QSB 3.3 engine and delivers a static line lo

Professor Martin Snaith, O.B.E., introduces an annual gathering that has grown over the years to become perhaps the world's foremost professional development forum promoting advances in sustainable roads worldwide. Over more than 15 years the Senior Road Executives Programme (SRE), organised by the internationally renowned Highways Group of the University of Birmingham, UK, in association with IRF, has established a worldwide reputation for providing top-quality professional development for executives worki

The new hydrostatic rubber-tyred AP 240 H roller from Ammann is said to set new standards when it comes to ease of use and driveability. Automatic speed control and a gentle start/stop function deliver outstanding results every time. Ammann’s Easy Load ballast system allows fast and easy machine weight adjustment, extending from 9,630kg up to 24 tonnes. An automatic tyre inflation system enables the tyre pressure and contact area to be carefully matched to the surface. Options include thermal skirting, a s

AFW350 and AFT350 are the latest medium-sized asphalt pavers from Ammann and are said to offer good manoeuvrability in confined areas. The hydrostatically driven machines offer a paving width from 1.8-3.5metres and the output potential of up to 230tonnes/hour. A wide range of optional equipment is available to improve paver performance. These include a vibratory screed or a tamping/vibratory screed that can be heated with either gas or electricity, and automatic lighting and temperature control functions.

At its annual plenary meeting held on 25 May 2010, during the 16th IRF World Meeting in Lisbon, the European Road Federation (ERF) elected a new President in the person of Jacobo Díaz Pineda. Mr. Díaz Pineda has been the Director General of the Spanish Road Association (AEC) since September 2006, and is also President of the Ibero-American Road Institute (IVIA). We took advantage of his presence in Lisbon to ask him a few questions about his new responsibilities:

An updated D6T bulldozer also will be introduced at Intermat. As one of the more popular machines in its dozer range, the D6T gets a revised engine that meets stage IIIB emissions requirements. It features a hydraulically driven on-demand fan that works in connection with an all-new cooling package and advanced electronic engine controls – together, the integration and control of these key components is able to deliver fuel savings of up to six percent, said the US equipment maker, depending on the applicat

The DX180LC-3 is the first of Doosan’s mid-range stage IIIB compliant excavators. Powered by a Doosan DL06 common rail six-cylinder turbocharged diesel engine, this 18tonne excavator uses a combination of EGR and DPF to meet emissions legislation. As a result, the new engine offers more power and torque than the stage IIIA DX180LC, and the potential to save 5-10% fuel consumption. A new cab offers greater room for the operator, while more glass helps visibility. Joysticks now feature new proportional thumb

Volvo’s F-series articulated dump trucks with full suspension can be specified with the company’s On Board Weighing (OBW) system, which won Gold in the Civil Engineering Equipment category of the prestigious Intermat 2012 Innovation Awards. The OBW cleverly monitors weight from pressure sensors in the ADT’s suspension system, to give payload information. The fully automatic system logs all transported loads.When used with Volvo’s CareTrack telematics system OBW can be accessed remotely, revealing total tran

The new ZRM 6014 road marking retroreflectometer from Zehntner is said to incorporate five innovations in one go: telescope handle and wheels as standard, colour touch display, camera, level meter and compass.

In this second of a two-part article, Jack Opiola, demonstrates that the imposition of a government provided GPS mandate to levy mileage tax could be eliminated by offering motorists transparent choices regarding their manner of compliance. The key to a mileage tax system without a GPS mandate is through offering motorists choices. Most motorists are consumers who are comfortable with selecting products and services from among options available in the marketplace. A mileage tax can be built upon this reali

The new generation JS crawler excavators from JCB are said to deliver increased performance along with reduced running costs. The JS220, JS260 and JS360 are all powered by Isuzu diesels that meet the Tier 4 Interim/Stage IIIB emissions requirements with reduced fuel consumption and increased torque rise. For developing markets, there is also a Tier 2 compliant version of the JS220 powered by a JCB 448 Dieselmax engine with a similar output to the 129kW Isuzu diesel in the Tier 4 Interim/Stage IIIB model. Th

The new ZRM 6014 road marking retroreflectometer from Zehntner is said to incorporate five innovations in one go: telescope handle and wheels as standard, colour touch display, camera, level meter and compass.

Danish company DELTA, a leading supplier of retroreflectometers for road markings and road signs, will launch its LTL-M mobile retroreflectometer at Traffex in Birmingham, UK.

Dynapac says that its new fifth generation CA single drum vibratory rollers, the CA5000, CA6000 and CA6500, offer performance upgrades over other machines. These machines have transverse-mounted engines that improve serviceability as well as optimised amplitude to boost compaction performance. A novel Active Bouncing Control is said to prevent damage to the machines as well over-compaction. High comfort cabs, good manoeuvrability and reduced noise levels and fuel consumption all help to make these machines

A study sponsored by the American Glass Bead Manufacturers' Association reveals that "a growing number of imported glass bead products for highway markings exhibit high concentrations of heavy metals, including arsenic and lead."

The forthcoming Tier 4 emissions legislation represents a great leap forward in technology, Mike Woof reports A high-profile focus on sustainability and reduced environmental impact is sweeping the construction sector in the European Union (EU) and the US. The EU and the US will implement regulations for the lowest emission off-road machines in history, with Canada and Japan expected to release similar regulatory programmes this year. The legislation being introduced will transform the construction indu

Powered by the six-cylinder Scania DC13 Tier 2 diesel engine with a gross power output of 368 kW (500 HP) at 2,100 rpm, the new Doosan DA40 articulated dump truck is said by the company to offer 10% more engine power than the previous MT41 model. The South Korean firm also says that the machine’s gross torque of 2,373Nm at 1,300 rpm, a 22% increase on the MT41, is the highest in the ADT market.Contributing to an overall 8% reduction in fuel consumption on the MT41 is the new ZF transmission offering eight f

The 5700C-Max unit from Power Curbers has now been used on a tricky shoulder widening job in New South Wales, Australia. The machine carried out the job close to Robertson in the Southern Highlands, about 1.5 hours drive to the south of Sydney. The job required the construction of a 200m long section of barrier, built to the requirements of the Roads and Traffic Authority (RTA). The contractor hand-formed the concrete shoulder as it was about 3m wide at the start and narrowed down to 1m at the end.

The National Roads Authority (NRA) in Ireland has announced it will expand its journey time system by expanding deployment of ANPR cameras from 80 to 126, allowing vehicles to be tracked between two points to calculate the flow and speed of traffic.

In Staffordshire, in the West Midlands region of England, some residents are reported to be so fed-up of waiting for traffic lines to be painted on roads by the local county council that they are threatening to do it themselves. Staffordshire County Council highways bosses say they can only take on four new traffic measure projects a year and have a waiting list stretching to 2028. Media outlets in the county report that the local authority currently has more than 70 requests from all over Stafford borough
