Highways

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,...

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...

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...

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...

Since the 2001 were constructed in Slovakia three highway tunnels with cement concrete pavements. This paper presents the Technical recommendation – the concrete pavement design method used for the design and calculation of pavement structures. According the different “climate conditions” in tunnels (concerning temperature gradients in slab), there are in...

Increasingly plastics become the material of choice by product designers because they provide useful properties and for this reason the worldwide production of plastics is growing year after year. At the European level the reference concerning the recycling and reuse of waste plastics obliges Member States to recover and recycle...

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...

This document describes the design and construction of the concrete pavement for the relatively steep access ramp bridge of the PEZA truck holding area of the Bale-Weil customs facility. The pavement design takes into account the expected change in usage after 2008 as a motorway offramp and harbour access route....
