Shonan Ohashi Bridge that is on Route 134 is a steel box girder bridge of 530m in length. Six years ago, fatigue cracks were found at the welding tips of bottom deck plates. After the full inspection of the asphalt pavement and steel deck bridge, it was found that the...

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...

Temperature changes within concrete pavements are transient. Therefore the temperature characteristics along pavement thickness are not linear and have to be split into constant, linear and equilibrium parts for further investigations. The linear temperature gradients are causing additional loading on concrete slabs, which if not considered will influence the long-term...

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...

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...

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...

The street is not a road because it fulfils multiple functions as a travel, social, cultural and economic space. The choice and organisation of surfacing play an important role, which must be clearly identified by roadway players. Cement concrete in all its urban forms occupies a place of choice in...
