Due to the durability advantages of concrete pavements, the application of concrete for roundabouts is gaining more and more popularity among commissioning authorities. In the Netherlands it is estimated that there are over 3,000 roundabouts. The market share of concrete is still growing. Concrete roundabouts can only be durable when...
Effect of Curling Behavior on Surface Smoothness of Continuously Reinforced Concrete Pavement
The curling behavior of the continuously reinforced concrete pavement (CRCP) under environmental loads was analyzed by measuring vertical displacements at a number of different longitudinal and transverse locations, and the relationship between the surface smoothness and curling behavior was investigated. Two different crack spacings were selected and at each discrete...
The Rehabilitation of the Underpass Bleicherweg in Zürich
In Zurich the underpass Bleicherweg had to be maintained. An important part of the job was the pavement. The civil engineering department of the city of Zurich decided that the original asphalt pavement had to be replaced with a concrete pavement. The base of this decision, minimize possible water vapor...
Probabilistic Life-Cycle Cost of Pavements Characterization and Application of Parameter Input Variation for Scenarios
Life Cycle Cost Analysis (LCCA) evaluates the economic performance of alternative pavement investments. Currently, practitioners treat input parameters as static, deterministic values, which although computationally simpler, will hide the implicit uncertainty underlying the analysis. Over the past decade, an emphasis has been placed upon accounting for uncertainty by treating input...
A Review of Mechanisms Associated with Premature Joint Deterioration in Concrete Pavements
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...
