Design

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...

For a long time the professional community in the Czech Republic have been criticizing the fact, that construction, maintenance and rehabilitation of motorways are not systematically studied in light of technology, functionality and reliability in connection with economy of these processes. Therefore the authors of this paper began an R&D...

Concrete pavements have long been considered the sustainable choice, simply due to their longevity. There are examples of both highways and local roads in North America where concrete pavements have lasted more than 50 years without significant maintenance. However, recent focus in North America on sustainable development and environmental stewardship...

Almost all jointed concrete pavements in the Netherlands, varying from low volume country roads to dual carriage motorways, are designed with the ‘Vencon 1.0’ program. The program needed to be upgraded to the Windows operating system. The upgrade also gave an opportunity to reconsider the design models of the old...

The pavement is the main and the most important component of a road. Pavements play a major role in the construction cost, maintenance and rehabilitation, traffic quality, vehicle and user costs. They are mainly divided into two types: asphalt concrete and cement concrete. For decision making in choosing the pavement...

Since the late 80ies in the Netherlands more and more cross-sections are constructed as roundabouts in stead of a cross section with traffic-lights. The pavements and prefabricated elements suffer from heavy traffic-loads and lots of maintenance was required. Therefore the last years it is investigated how sustainable roundabouts could reduce...

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 properties of concrete mixes produced by replacing the coarse aggregates by milled bituminous materials of the same grading are studied in the laboratory. The milled bituminous material used comes from reclaimed asphalt concrete produced in road maintenance works. The properties investigated are compressive and flexural strength, modulus of elasticity,...

Superbus is an innovative new concept in personal public transport, developed by the Delft University of Technology. The Superbus consists of a highly advanced vehicle that can reach speeds up to 250 km/h a special Supertrack Infrastructure and advanced IT applications for services on request, road handling and comfort and...

The performance of road surface is the first and main indicator of information of the condition of the road. For some singular damages in-depth analysis is not necessary; for these an instruction for an appropriate maintenance measure is possible. However, by area-wide recurrent or systematic damages causes are important in...

In 1999, a 60 000 m2 large concrete pavement was completed in a Swedish harbour. The largest part of the area consisted of 200-210 mm thick plain jointed concrete pavement (PJCP) overlaying an old asphalt pavement. The design was based on certain prerequisite concerning traffic loads, i.e., axle loads and...

The advantages of prefabrication and precasting are well known in the building industry: a short building-time, efficient use of materials, optimum quality control, financially appealing and sophisticated logistics. In residential, commercial and industrial building in the Netherlands, the use of prefabrication is common practice. It would be logical to assume...
