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...
In Situ Measurement of the Capillary Pressure in Concrete Road Construction
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...
Sustainable Concrete Pavement Design Solutions Applied on the Largest PPP Motorway Construction Project in Europe
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...
Measurements and Evaluation of the Bearing Capacity of Cement Concrete Pavements
Concrete pavements dynamic loading tests are one of the diagnostic method to which the goal is to obtain background for evaluation of bearing capacity. In this article are described experimental measurements and results of these measurements on various slab locations, taken from measurements for recognition of connection between slabs and...
France Fifteen Years Review on the Behaviour of Composites Pavements Concrete on Asphalt Mix
On the initiative of concrete road professionals on the one hand the French cement industry represented by its trade association CIMBETON and concrete pavement construction companies represented by the trade association SPECBEA and the French road administration represented by SÉTRA on the other hand, a new concrete pavement...
Classification and Methods for Rehabilitation of Concrete Pavement- a Spanish Example
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-situ Architectural Concrete and Pre-Dosed Micro-Concrete for Wear Thin Layer Pavements in Urban Areas Diogo Menezes Square as an Example of Environmental Renovation
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...
Slab Curling and Rolling Resistance
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...
How to Build Smooth Concrete Roads and Measure Success the Moment You Pave
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...
Concrete Roads in Poland the Case for Selling Non-Mainstream Infrastructure Technologies
The paper illustrates, on the grounds of Polands case, the concrete roads network development in a jurisdiction dominated by asphalt roads. The author reviews typical drawbacks apparent when promoting concrete roads, and identifies several most arresting phenomena that have led to the current technological stalemate. The goal of the paper...
Precast Concrete Pavement Innovations, Performance and Best Practices
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...
