While diesel engines continue to be developed, there is no mistaking the current plans for electric driveline projects - Mike Woof writes The growing worldwide consensus on the massive threat to humanity posed by climate change means that the need to reduce exhaust emissions from transport and construction is becoming ever more pressing. As a result, industry is changing and new solutions are being found for transport and construction that will help lower environmental impact. Although many solutions are

Embracing change; handling data as an evolutionary process, Mike Woof writes. Bentley Systems believes that it is on the cusp of a revolutionary step in computing that will boost the working efficiency of companies right across industry. Bhupinder Singh, chief products officer at Bentley Systems explained that its key advance will allow firms to utilise what they already have, but more efficiently. He said, “Companies are effectively analysing just 1% of their data. The rest is ‘dark data’ that is stored

Advances in asphalt compaction are offering improved performance right across the spectrum of size and capacity – Mike Woof writes. New asphalt compaction machines are offering major gains in performance as firms develop new systems. Large and small asphalt compactors now offer higher output than earlier generation machines, while delivering better quality and lower fuel consumption as well as gains in reliability, durability, safety, ergonomics and operator comfort.

Asphalt paving equipment manufacturers from around the globe are rolling out new and improved machines - Mike Woof writes The pace of development within asphalt paving technology is quick, with new machines being unveiled all around the world. Machine manufacturers in Europe, China and Japan have been re ning and developing their technologies, which are aimed at differing global markets.

Reducing the death and injury toll on the world's roads is a key priority. It is estimated that every year, 1.25 million people die on the world’s roads. With motorisation and urbanisation to increase in many parts of the developing world in the years to come, there is every likelihood that this number could rise. Can you explain why so many lives are needlessly lost every year on our roads and why greater action isn’t being taken to address this?

John Deere’s recent acquisition of the Wirtgen Group was driven by the way in which two leading equipment manufacturers could come together with no product overlap and target strong investment growth in the world’s highways sector

Police budgets are being slashed, staff numbers are falling and Europe’s long-term trend towards ever-fewer road deaths has ground to a halt. Does Europe’s road network face a far more dangerous future? Geoff Hadwick reports from TISPOL 2017 in Manchester, UK. Europe’s road safety record is under threat. Lower and lower funding levels have become a very serious, and very worrying, problem for the EU’s traffic police bosses. They know that they must find new ways to focus road users on changing their beha

The highly successful IRF Middle East & North Africa Regional Congress has set foundations for knowledge partnerships The premier road engineering and mobility event in 2017 came to a close with a renewed call for consensus-building and knowledge partnerships to address key sustainability and mobility challenges. More than 200 papers were presented by authors from 50 countries, representing an enormous body of knowledge for policymakers and transportation stakeholders to work with. The Congress was also

Seattle's State Route 99 viaduct is coming down. David Arminas was on site. Bertha, the world’s largest diameter earth pressure balance tunnel boring machine, with a cutterhead diameter of 17.5m, is no more. Her 2.7km journey underneath the waterfront area of Seattle finished on April 4 and the power went off for the last time on an extraordinary TBM that had finally completed an extraordinary job. “A small sidewalk job would have had more impact on city traffic than we have had,” says Brian Russell a v

The new AMOPEPPER plant is now being tested at the AMOMATIC facility in Paimio, Finland. The way the system works is that the plant can be moved to an area where RAP material is available or material can be transported to the plant area. Once these two are ready, RAP material is fed into the process and the end result is hard stones of two different sizes as well as bitumen pellets. These are squeezed so hard that nearly all moisture is eliminated. It has already been tested that these pellets can then

Astec has commissioned a highly sophisticated asphalt plant in Mexico City to meet specific customer needs for a high quality output with minimal environmental impact. Equipped with Astec’s latest technology, this is a low emissions plant and is the first in Latin America that features the firm’s V-Pack Stack Temperature Control. The low emissions performance was a key factor in the supply deal, so as to meet the needs of the authorities in Mexico City. The plant is equipped with Astec’s Phoenix Talon low

A good quality mix plays an important role in road construction and the asphalt manufacturing process starts with the mix design in the laboratory, which takes place under controlled conditions and depends on the materials available locally. A mix design that matches the plant's limitations has a higher probability of success. The properties of the aggregates, such as water absorption, abrasiveness, and the equivalent sand index, may influence the quality of the mix produced in the plant. In the laboratory

An asphalt plant from ADM has helped in the reconstruction of the runway at South Caicos Airport. Herzog Caribbean recently took delivery of its new asphalt plant to supply material for the runway overhaul on South Caicos Island. The plant, an ADM EX120, delivered 23,000tonnes of material for the project without any downtime, allowing for an April 2017 completion. A division of Missouri-based Herzog Contracting, Herzog Caribbean operates out of Providenciales, the capital city of Turks & Caicos, British We

The use of a new Ammann plant is helping to improve RAP usage in China with the manufacturer and the Chinese Government working together to gather and evaluate production data. A key Ammann customer in China is helping pave the way for the expanded use of recycled asphalt pavement (RAP) in the country’s road projects. Tianjin TianHeJianLing Road & Bridge Engineering Technology is a pioneer in the use of RAP in China. The mixes its Ammann ABA UniBatch and Uniglobe asphalt plants produce are being scrutinised
