Resources

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...

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...

Concrete pavements are vulnerable to cracking already in the plastic material stage, i.e., before the concrete has reached a significant strength. Due to the evaporation of water at fresh concrete surfaces, a capillary pressure is built up in the pore system of the material. This underpressure leads to the so-called...

The precast concrete pavement (PCP) technology is gaining wider acceptance in the US for rapid repair and rehabilitation of concrete pavements as well as for heavily trafficked asphalt concrete intersections. Although the US PCP technology is of recent origin, with projects less than about 12 years old, many projects have...

Highways superficial rehabilitation appears nowadays as one environmental friendly option to increase the service life of pavements. The remaining structural section is responsible for providing enough resistance for the ongoing traffic loads. The basic goal of this kind of treatments is to recover a certain level of comfort and security...

In this communication the development of non traditional-solutions for pavement surfaces will be assessed, by the use of colored pre-dosed micro-concrete or in situ concrete in thin layers of high performance architectural applications for urban, pedestrian, cycling and roads. This assessment will be focused on frequently technical constructive barriers inherent...

In a life cycle analysis a higher investment cost is justified by lower maintenance costs, less and fewer traffic flow intrusions, and a longer technical life. All these factors contribute to a reduction of the carbon footprint. To further improve the sustainability of PCC pavements the rolling resistance should be...

The Strategic Highway Research Program 2 (SHRP 2) recently completed a study entitled, “Real-Time Smoothness Measurements on Portland Cement Concrete Pavements during Construction”. As part of this project, the feasibility of this technology was explored. There was both an evaluation and demonstration of emerging and proven technologies. Model specifications and...
