Premature deterioration of sawn joints has been reported in some cold climate regions in the USA. This paper reviews the multiple mechanisms have been found to contribute to the deterioration. Laboratory and field investigations have shown that freezing and thawing of saturated concreted is a dominant factor. Magnesium and calcium...
Extending the Service Life of Structurally Sound Concrete Roads in England
A number of concrete surfaced roads in the UK have been in service for over 30 years. In some cases, the original surface laitance applied to these carriageways is becoming worn, leading to reductions in texture and skid resistance, a combination that has been shown to have a negative effect...
Environmental Performances of Roller Compacted Concrete Pavement
The use of RCC is now well established for industrial pavements, and is spreading in North America and recently in Europe for transportation pavement with high mechanical performances requirements such as Tram or Bus platforms. Cost advantage and mechanical performances are two undeniable benefits of this technology. The development of...
Skid Resistance of Concrete Pavements and their Durability
The article states that a relative traffic accident risk depends on the values of skid resistance and its durability, which are both influenced by the texturing of Concrete pavements (CP). From the very beginning of the CP construction in the Czech Republic, transverse tining was used for surface texturing. The...
Re-use of Marginal Aggregates in Cement Bound Mixtures for Pavement Foundations
The paper reports the results of an experimental study aimed at designing cement bound granular mixtures for pavement foundations, made exclusively with marginal materials, namely electric arc furnace steel slags, ladle furnace slags, waste foundry sands, glass wastes and coal ashes, used with different proportions. The laboratory investigation has been...
Multi-Funcional Noise Reducing Pavements Made of UHPC – Materials Design and Construction Technology
The constantly rising traffic volume is leading to high mechanical stress of the pavements. As a result, the requirements of maintenance, refurbishment and renewal are increasing. In contrast to this, financial resources are decreasing constantly. Moreover, the increasing traffic noise emissions are experienced as growing stress. New, highly sustainable and...
Operation Experiences on Concrete Pavements During the Last 10 Years in Hungary
Since the middle of 90s in Hungary the permanent deformations of semi-rigid asphalt pavements have become a major problem due to increasing traffic and changing climate conditions. It has been a particular challenge concerning the M0 motorway around Budapest exposed to the most serious heavy vehicle traffic. The preceding test...
Recent Advances and Uses of Roller Compacted Concrete Pavements in the United States
Roller Compacted Concrete (RCC) is a no slump concrete that is placed by an asphalt paver and compacted with vibratory rollers similar to asphalt pavement construction. RCC has long history of good performance as a pavement for ports, container yards, and manufacturing plants. This paper will summarize a recent survey...
Concrete Pavements and Structures for Dedicated Public Transport Lanes
Bordeaux, Clermont-Ferrand, Caen, Grenoble, Lille, Lyon, Marseille, Montpellier, Nancy, Nantes, Nice, Orléans, Rouen, Saint-Étienne, Strasbourg, Paris . Which city hasnt developed or is about to develop its own network of public transport on dedicated lanes? Users warmly welcome this mode of public transport, typical of urban renewal projects for...
Flatness and Levelness of Concrete Pavements for Industrial Areas Requirements and Evaluation Methods
Among various construction activities, related to concrete pavement technologies, an important role is reserved to industrial floors; these structures, in many cases, present the same technical problems of road pavements. Characteristics, construction techniques, exercise conditions, maintenance and control of industrial pavements, in effect, are very similar to the ones usually...
Towards a Standardized Design Structure for Concrete Tramways in Flanders
For more than ten years tramway structures in Flanders have been built in concrete, particularly those which are subject to traffic loading by trams and city buses. As there has never been a standardized design, a wide range of different solutions have been tried, either in jointed concrete slabs with...
Concrete Pavements in Motorway Service Areas
Even if the forecasts for the development of goods traffic are more cautious than they were just a few years ago, growth remains strong in Europe. Most goods will continue to be transported by road in the future. Not everywhere, however, has the expansion of motorway rest and service areas...
