The use of demolished concrete as recycled aggregate in new concrete is a promising solution within the context of sustainable development. However, this application is still limited in the construction sector due to the lack of knowledge. In that context, Ifsttar (France) and the French industry's major players have finished...

In recent years, several high-profile road tunnel fires have taken place across Europe. These fires inevitably led to important structural damages and even loss of lives. In all of these tunnels, national mandatory safety regulations were implemented. Nevertheless, disasters could not be averted. Apart from a deep knowledge of safety...

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...

Road tunnels and railway tunnels generally, located in sensitive sites, must not be considered simply as an extension of standard open-air sections. For the road tunnels, the thickness of the structure, its future maintenance and the consequences on traffic, as also the effect on lighting of pavement lightness have to...

This paper presents a structural, functional and economic evaluation model for Jointed Plain Concrete Pavement (JPCP). The model was implemented by using a computer program developed by the authors at the Department of Civil, Building and Environmental Engineering of University of Rome “La Sapienza”. This paper will describe this versatile,...

From both an environmental and economic point of view, the availability and performance capability of infrastructure traffic areas today and in the future is of the highest priority. This applies to both public and private roads and air traffic areas, as well as for busy parking and logistics areas and...

Skanska a.s. is one of the leading construction companies, who successfully execute concrete pavement projects in Czech Republic, Slovakia, Poland mostly on motorways and airports. To achieve the best quality, durability and cost-efficiency, it is needed to put an effort to research and development. Recently experts from Skanska are leading...

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...

Due to its central location in europe Germany is a typical transit country, where traffic load by heavy traffic increases anually. Highways are especially affected, with freight traffic not only increasing in number but also showing a trend of 5-axle vehicles with larger utilization of the allowed axle loads at...

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...

The project deals with research on effective composite steel and concrete bridge structures, profiting from directly running cement concrete pavements. The aim is an innovative layout solution, technology of construction and maintenance and research of new formulas for concrete parts which will lead to lower collective costs of production and...

The Castilla & Leon Regional Government has built a new road between the towns of Castrofuerte de Campos and Toral de los Guzmanes, located in León Province, in the Northwest part of Spain. It includes a 324m long and 10m wide bridge allowing local traffic to avoid a long detour...
