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...

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...

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...

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...

Continuously reinforced concrete pavement (CRCP) has been constructed on major highways in several countries since the 1940’s. A large majority of these pavements have carried very heavy truck traffic but required low maintenance. Some have experienced problems due to inadequate design, support, and construction. This paper focuses on factors that...

This article gives an overview of the work that has been done so far to transform the N49 Antwerp- Knokke into highway E34. The work involved fits in with the major overhaul of the N49 between Antwerp and Knokke as far as the E34 motorway. According to the Flanders Regional...

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...

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...

Construction of Cement Concrete Pavement on National Highways started in India during the year 1991 when Ministry of Surface Transport, Government of India, under took four laning of 112 Kms. long Delhi – Mathura Section of NH-2. Construction of Cement Concrete Pavement picked up in 1998 with the implementation of...

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...
