The Walloon motorway is the east-west axis in the southern part of Belgium linking the north of France to the southwest of Germany. It was built in the beginning of the 1970’s as a part of the Belgian motorway development program. The design traffic was about 10.000 vehicles a day...

In the construction of airport pavements, one possible way to save resources and lower construction costs is to reduce the slab thickness by introducing high-strength concrete. Cost-saving would be even more effective if the high-strength concrete could be laid without using any special materials or construction methods. To this end,...

This paper presents the conduct and outcomes of a series of investigations aimed primarily at determining the noise attributes of several rigid and flexible pavement surfaces currently in service in Australia. The investigations, which included both Portland Cement Concretes and Asphaltic Concretes, have been conducted over the last five years...

The lack of quality data that relates tire-pavement noise to the texture of concrete pavements has hindered the pavement community in both understanding the phenomena and finding ways to minimize its impact. The National Concrete Pavement Technology Center (USA), the US Department of Transportation Federal Highway Administration, and the American...

Fibrous concrete has a history in pavements. In the 80ties fibrous concrete became popular thanks to pperspectives such as reduced pavement thickness and increased joint distances. Unfortunately, not all promises were kept and the fibrous concrete ‘silently’ disappeared from the pavement construction scene. However, in industrial floor construction material research...

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...

A Removable Urban Pavement (RUP) is a pavement that can be open and closed rapidly, with light facility, for an easy access to underground networks. It has the same difference with a conventional road as a window compared to a solid wall. No such a pavement seems to have ever...

Multicriteria aid to decision-making is a set of theories and methods designed to assist decisionmakers in selecting one out of several possible alternatives while considering various points of view or “criteria”. In managing their assets, road managers are often faced with the difficult choice of type of surfacing to suit...

From many decades concrete has been successively applied in road construction in many countries. The scale of these applications is different depending on local experience and tradition. Concrete pavement is many a time more profitable solution than bituminous pavements. It refers not only to the construction of motorways or express...

Plain Jointed Concrete Pavements (PJCP) are used on Swedish concrete roads. In the Swedish road construction specifications there are two alternatives for bound roadbases which can be used in concrete pavements. Generally a 150 mm thick cement-bound roadbase (CG) has been used. As an alternative a 100 mm thick asphalt-bound...

In 2005, a forensic engineering study was conducted on a recently constructed concrete pavement located along the Pan-American Highway (CA-1) in El Salvador. The primary distress was observed to be full-depth cracking, predominantly in the longitudinal direction. This type of cracking was noted to occur just a few months after...

For three years the Roads and Traffic Administration (AWV) of Flemish Brabant in Belgium has been using the technique of ultrafast-track (UFT) concrete paving for the rehabilitation of several road sections. The aim is to achieve a compressive strength of 40 N/mm² on cores after 30 to 36 h of...
