Features

Mobility and versatility are key features of some of the latest asphalt plants now being offered. Ease of transport and quicker assembly and commissioning are capabilities seen on new asphalt plants introduced during 2019. The ability to use RAP is another important feature being seen in all of the sophisticated new plants coming to market.

Another roundabout is being built in the US where the public remains sceptical but agencies and contractors are on board, writes David Armina

New advances in soil compaction technology will help deliver speedy construction to tight quality standards - Mike Woof writes

Three major bridge projects in the US have won key awards for engineering excellence. The three structures have been given the awards by the American Segmental Bridge Institute (ASBI). The bridges are: the Marc Basnight Bridge (Bonner Bridge Replacement) in North Carolina, the St Croix River Crossing in Minnesota and the Bayonne Bridge in New York/New Jersey.

The Qatar Transportation and Traffic Safety Center (QTTSC) at Qatar University College of Engineering (QU-CENG) has signed a memorandum of understanding (MoU) with the International Road Federation (IRF Geneva), Geneva (Switzerland). This is intended to further expand and consolidate collaboration and exchange of expertise particularly on traffic safety.

A move to warm mix should be just one part of a much broader strategy to reduce the impact of road paving activities on climate change, says Nynas.

Though warm mix technology has been around for decades, take-up has been patchy - will renewed environmental pressure change that? asks Kristina Smith

The use of sophisticated machine control technology is integral to delivering high quality and productivity for concrete paving operations

A new bridge in the US state of North Carolina has won a key award for excellence – Mike Woof writes

Global commitments to reduce carbon emissions and simultaneously increase the resilience of critical infrastructure to extreme weather events have placed greater societal expectations on road builders to design and deliver sustainable pavements that are both affordable and scalable.
