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...

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...

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...

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...

In the last few years cracking in concrete pavements often is attributed to alkali-silica-reaction (ASR). Although this is a very important aspect other impacts such as traffic loads and restraint stresses due to thermal and hygral effects may not be neglected. In many cases interactions between various causes can become...

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...

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...

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...

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...

The authors present the sustainable pavement design solutions applied on 106 km long section of A2 toll motorway in Poland. For this largest infrastructure project, realized in the frame of Public-Private Partnerships (PPP), the concession model, where the concessionaire has to be paid by public part for the accessibility of...

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...

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...
