A variety of systems are available for quickly and efficiently removing water from roads as Patrick Smith reports The presence of water in a highway layer reduces the bearing capacity of the road, and in doing so it also reduces the structure's lifetime. Indeed, the recent extremely cold winter in many parts of Europe has shown that in colder climates there is a risk of frost damage when water is present resulting in costly potholes, so drainage systems performing properly are important in road design.

Quicker, better, more cost effective materials testing - Kristina Smith writes. Most developments in materials testing technology involve updating and upgrading existing machines, either to meet changes to standards or to satisfy new needs in the market. And occasionally, a manufacturer will come up with something completely new. PUMA - the precision unbound materials analyser - falls into the latter category. It has been developed by Cooper Research Technology and Nottingham Transportation Engineering Cen

German firm Vögele has built the world's largest and most sophisticated paver manufacturing facility - Mike Woof writes. Part of the Wirtgen Group, Vögele has benefited from the massive investment the company has made in all of its major manufacturing operations. The Hamm, Kleemann, Vögele and Wirtgen facilities in Germany have all been improved, with both Kleemann and Vögele now using brand new, purpose-built factories constructed on green field sites.

Organisers of the International Show of Public Works, Construction and Mining Machinery have made every effort to assist the sector on the road to recovery Organisers are sure that the upturn in business seen in some sectors will make SMOPYC 2011 an "outstanding event." The 15th event, being held at Zaragoza Trade Fair Centre, Spain, from 5-9 April, will boast nine halls (100,000m2 of covered space) and 200,000m2 of outdoor space to display heavy machinery, along with demonstrations and sponsored areas.

An innovative solution was put forward to support slip roads on a Dutch motorway. Patrick Smith reports The 2010 opening of the A7 motorway extension on the southern ring road of the city of Sneek, The Netherlands, brings an end to local traffic misery. By using innovative Tensar Geocell Foundation Mattress technology over weak estuarine clay, MNO-Vervat Noord, the main contractor, constructed a key junction and its slip roads in weeks instead of months, with considerable cost savings. The conversion

With the asphalt paving segment split broadly into two methods, American or European,. it is no surprise that manufacturers. from these countries have dominated the market for some years. An interesting development in recent times has been seen with various European firms developing asphalt pavers to suit North American needs, including BOMAG, Dynapac and Vögele. Caterpillar and Volvo by comparison both offer both European and US-style pavers, with separate model ranges that have been developed over many ye

Duplex A86 tunnel. The low risk found for driving through the tunnel is primarily due to the low volume of traffic of around 11,000 vehicles/day and the ban on HGVs and the transport of hazardous goods.

Variable Message Sign systems are helping ease traffic congestion and keeping drivers better informed on key highways across Europe and the rest of the world. Guy Woodford looks at some of their recent applications By coupling its Intelligent Travel Time System (ITTS) with Bluetooth technology, Alcatel-Lucent is measuring traffic flow in real time and conveying it seamlessly to local authorities in the French city of Vélizy-Villacoublay. The city, a major business enterprise hub 14km south-west of central
