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

There are important methods aimed at the reuse and recycling of reclaimed asphalt pavement (RAP) a number of problems have to be solved however, mainly concerning the elimination of moisture content and how best to heat the RAP without damaging the binder. When RAP is used in percentages of up to 30-40% of the final mix, heating can be carried out through direct contact with hot aggregates. On the other hand, in order to use higher RAP percentages, up to 100%, the plant has to be fitted with a specific h

The use of sophisticated machine control tools from Trimble has helped US contractor Beaver Excavating deliver a project more efficiently. In the US, earthworks contractor Beaver Excavating is testing Trimble’s new machine control platform and is achieving high accuracy and consistent excavation and grading in less time. Jim Sterling, survey and GPS manager for Beaver Excavating, explained that the company has been a longtime Trimble customer. Over the years, the company has added additional machine

Berghaus’ ProTec-Tor 50 and ProTec-Tor 120 mobile crash barriers are tool-free solutions to open a quick access point for emergency services. They are part of the German manufacturer’s ongoing commitment to development of mobile crash barriers. In an emergency, it takes only a couple of fast actions to release the force-fit connection of the ProTec-Tor 50 and ProTec-Tor 120 mobile crash barriers and open the ProTec-Tor elements. Fire brigades, emergency services and police then have easy access through the

The WRM programme has taken shape with details to be completed by early September, with the receipt of full papers from the authors, due by 31st July 2017. There is considerable progress with regard to the Global Transport Ministers’ Meeting, with confirmations of participation received from various European and African nations. The ministers will be accompanied by small delegations. The IRF Geneva office is looking forward to sharing more detailed information regarding the programme in the next couple of

IRF Geneva was one of the key supporting organisations of the World Transport Convention (WTC 2017) held on 4th-6th June 2017 in Beijing, China. Hosted by the China Association for Science and Technology (CAST) and organised by China Highway and Transportation Society (CHTS) the convention had as its theme “Green and Integrated Development through Innovations” and attracted 1,820 papers from all over the world and 5,000 delegates. Kiran Kapila, IRF chairman, delivered a keynote address in the opening

The IRF Middle East & North Africa Regional Congress & Exhibition will offer exceptional insights and networking opportunities with more than 150 industry and scientific thought leaders. Dubai is the perfect host city for this event, especially in light of the Road & Transport Authority’s (RTA) ambitions to offer advanced transport sector services technologies to support Dubai’s growth plans through policies and legislations, innovative approaches, and world-class practices and standards. Thanks to the

In the coming age of the autonomous vehicle, fast and accurate LiDAR surveying will be increasingly important, explains Valdis Vanags. The game-changing introduction of autonomous vehicles relies not only on intelligent traffic systems but well maintained roads to help computer-guided systems navigate using road markings. Laser scanning technology, too, is a game changer when it comes to planning and executing many civil engineering projects, including transport network upgrades and smart city initiatives.

The market for piling machines is seeing new technology come to market – Mike Woof writes UK firm BSP is now offering an improved range of piling systems, with its SL30 model and compact BH120. The SL30 can be used to drive Z piles in pairs and its hammer has a drop weight of 2.5tonnes, delivering an impact energy of 30kNm at up 84blows/minute. The SL piling hammer is designed for driving sheet piles and small bearing piles and is available with legs and inserts for use when freely suspended or with back
