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...
Genesis of a Comprehensive Concrete Pavement Noise, Texture, and Friction Data Collection Program
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...
Fibre Concrete Mixes Blending Plain and Reinforced Concrete
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...
Guided Public Transport Infrastructures Contribution of Cement Concrete in Innovative Designs
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...
Development of a Removable Urban Pavement Technology
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 the Choice of Road Surfacings
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...
The Road Traffic Noise Attributes of Some Portland Cement Concrete Pavement Surfaces in Australia
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...
Investigation of Premature Concrete Pavement Distress on the Pan-American Highway in El Salvador
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...
Ultra Fast-Track Concrete Paving Belgian Experience
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...
Urban Works in Cement Concrete: Cross Experiments Between the Road World and the Street World
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...
Skid Resistance in Austrian Tunnels with Special Attention to Concrete Pavements
The skid resistance of a road surface is of high importance for road safety. All kinds of controllable acceleration, deceleration and steering actions are only possible, if the road surface offers at least the same adhesion as the drivers action requires. It gets even more difficult due to the fact...
Walloon Design Method for Concrete Pavements Improvements Since 2003
The Administration of the Ministry of Equipment and Transport of the Walloon Government, together with researchers of the Federation of the Belgian Cement Industry and the Belgian Road Research Centre, put into practice a software program for the structural design of pavements. This program is in use for several years...
