Highways

The technique of continuously reinforced concrete is used in Belgium for the construction or rehabilitation of heavily trafficked motorway sections. Since a few years, double layered CRCP is being considered in order to improve the rolling noise characteristics of the surface. In this paper, two worksites where CRCP was used,...

The paper resumes the development of the concrete roads in Czechoslovakia, resp. in the Czech Republic over the span of time between two major specialized events held in Prague, in particular the XIVth World Road Congress 1971 and the 12th International Symposium on Concrete Roads in 2014. The concrete pavements...

The use of continuously reinforced concrete pavement (CRCP) is enjoying a renaissance in the United States (USA). CRCP has the potential to provide a long-term, “zero-maintenance,” service life under heavy traffic loadings and challenging environmental conditions, provided proper design and quality construction practices are utilized. In the USA, the Federal...

Concrete, used in the production of highways and pavements, may deteriorate after many years of service, due to severe exposure conditions. Due to strategic and economic importance of such infrastructures, swift action for repair works is required. Repairs with conventional concrete may take long time for gaining adequate strength, where...

The longitudinal displacements of the terminus of the continuously reinforced concrete pavement (CRCP) without the terminal anchor lug system were measured and analyzed to investigate the maximum terminal joint width and the necessity of the anchor lug system. The terminal movements under environmental loads were measured at the CRCP sections...

For many years, the traffic volumes and percentage of heavy traffic on German roads and motorways have steadily increased and this trend is expected to continue in the future. To guarantee mobility in the future, road construction with a maximum service life and a minimum of necessary maintenance are needed....

The paper describes the actual possibilities of using concrete pavement in a roundabout. Concrete may be better material for aprons than conventional cobblestones. It can be better for both durability of the road and for road safety. If heavy vehicles often pass through the cobblestone pavement in the apron, the...

In 2009, an innovative road pavement "Continuous Reinforced Concrete Pavement with Ground Texture" was successfully realised by HeidelbergCement AG with the pilot project, "Geseke access road ". In an extensive measurement programme, long-term measurements are being made over a period of 5 years to investigate the behaviour of the carriageway...

On the beginning of third millennium we, in the Czech Republic, can also notice a big construction boom in the area of bicycle roads and trails. The rehabilitation of existing roads, temporary solutions (e.g. traffic sign placement) overweight the others. Other systematic approaches are also built and they bring a...

Concrete pavements are continually subject to the effects of weather and traffic. These may cause tensile stresses at the top and bottom of the concrete road slabs. The resistance of the concrete slab to such effects depends on a large number of factors. In particular, the concrete tensile strength and...

Countries that have little experience in concrete pavement design, application and operation, like Turkey, may face many difficulties while planning of concrete pavement construction (life-cycle, design, cost, technology and equipments etc.). We want to share as follows; managing the project, road map, learning phase, experiences, difficulties, mistakes and best practices...

Public lighting contributes to the safety and quality of life in urban areas and, like all services, is confronted with the challenge of “doing better with less.” Closer ties between the trades of the road and lighting offer proven opportunities for significant economic and environmental gains once steps are taken...
