Bituminous Materials with a High Resistance to Flow Rutting

After recalling the mechanisms of rutting, this publication identifies the main parameters affecting resistance to rutting in bituminous materials, presents the methods of characterizing this resistance, the methods of calculating rut depth and the practical mix design methods aimed in particular at achieving high resistance to rutting and describes the mix compositions to be used on sites with specific requirements for rutting resistance.

Continuously Reinforced Concrete Pavements

This report gathers the main features of the state of the art on continuously reinforced concrete in 23 states (Australia, Belgium, France, Italy, Japan, Malaysia, the Netherlands, Portugal, Republic of South Africa, Spain, United Kingdom, and 12 states of the United States). The aim of the report is to provide authorities in charge of building and managing road networks with the information needed for facilitating their decision making with full knowledge of the facts.

Porous Asphalt

For about ten years, the use of porous asphalt has grown rapidly in some countries where the material is used for a large part in road surface maintenance works on highly trafficked roads. Some countries even impose porous asphalt on motorways beyond a certain level of traffic. On the other hand, some countries remain very reserved. How should porous asphalt be designed and laid in order to obtain the noise reduction aimed at? How long will the specific functional qualities of porous asphalt wearing [...]

The Use of Roller Compacted Concrete for Roads

Regarding its use for pavements, roller compacted concrete (RCC), could be considered as a hybrid between cement treated granular material and vibrated concrete. Indeed, RCC pavements can carry traffic directly on the finished surface, a possibility not offered by cement treated bases. Its simple implementation, easy construction, reduced labour requirements and high production rates result in considerable savings in comparison with other alternatives. Moreover, and considering their use for [...]

Evaluation and maintenance of concrete pavements

The road asset of a country or region is of considerable value. Owners who have chosen to invest in concrete pavements for all or part of their road network or their airfields have often done so hoping to obtain a lasting infrastructure and a guarantee of maintaining traffic in all weather conditions. This crucial objective is sought after for the most strategic roads and runways of the transport infrastructure. This report is a source of information and consideration for owners of road, motorway [...]
