Recent years have witnessed the significant development of public surface transport systems: in our cities: tramways, systems on tyres, right-of-way bus corridors, etc. This phenomenon is a response to the high stakes involved for mobility and communication in urban areas. These projects have seen the emergence of new problematics related...

The long service life of cement concrete roads, as well as the new objectives of contracting authorities taking into account significant extensions in hypotheses on the design service life of roads, streets and runways, oblige the technical civil engineering community to plan much more than in the past for the...

The brightness of concrete pavements is, next to a multitude further, an essential advantage of this method of building vis-à-vis bituminous pavements, because brighter street surfaces affect positively the safety of the road users. Bright concrete surfaces provide above all an increase of safety in rain and in darkness (especially...

Traffic noise is one of the major environmental concerns within the countries of the European Union. 80 to 90% of the traffic noise pollution is generated by road traffic. The major part of the noise emitted by vehicles on roads in the mid- to high-speed range is nowadays due to...

In the technology of the Roller Compacted Concrete (RCC) for pavement, various types of aggregations are used classically as aggregates, such as the crushed and the rolled aggregates limestone and siliceous, giving concretes with a relative density in the order of 2200 to 2300 kg/m3. In the present work, we...

Contractor VBG NV from Heusden – Zolder started the execution of the above-mentioned site in August 2005 for an amount of 2 million EUR. It concerned large-scale structural maintenance: the repair of the longitudinal joint between the hard shoulder and the right-hand lane (continuous reinforced concrete) had been necessary for...

In certain areas there is a need to surfacing sand roads due to agricultural developments: mechanisation and efficient management of farming activities are essential. Farmers must have direct access to the fields at all times without too many obstacles. However, attention must also be paid to various other aspects: environmental...

The concrete road technique has been used for many years for the creation or improvement of roads in land reparcelling project areas. The designs used for these roads have had to develop for a variety of reasons: 1. Vehicles are becoming increasingly heavy. Semi-trailer rigs carry crops directly from the...

On 13 December 1967, the “E5” Partnership was established in Belgium with the objective of constructing the Brussels-Liège motorway. This was the missing piece in Belgium of the E5 European route, which extends from London over Calais-Jabbeke, Brussels, Liège, Cologne, Frankfurt and Vienna to Ankara. Later, the name E5 was...

The rehabilitation of the Ring Road of the city of Antwerp is the largest and most discussed road construction project undertaken in Belgium within the last decades. The Antwerp Ring Road is one of the most trafficked urban freeways of European importance. Six radial freeways are tying into it and...

The project concerns the design and supervision of construction for the realisation of a new combined tramway and bus lane linking the main railway station of Gent (Belgium) with the exhibition halls at Flanders Expo. Fundamental criteria for the design included the durability of the pavement, a pleasing appearance compatible...

The Netherlands has made a clear decision to increase traffic mobility by reducing the use of traffic lights wherever possible. If traffic lights are not to be used, crossings need to be changed. The easiest solution is to change crossings into roundabouts and this solution (depending of the volume of...
