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...

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...

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...

Innovative solutions for transport infrastructure are needed to meet future mobility needs, especially in urban areas. Recently, Bombardier Transportation has developed a new system for supply by induction of electrical public transportation vehicles. It consists in integrating electrical supply cables in a prefabricated concrete slab implemented in the road. These...

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 fundamental goal behind any pavement design and construction project is to provide a system that will survive the predicted traffic and environment for the selected lifetime. Considerable effort is paid to the structural design of a pavement in order to reach that goal. On the other hand, the concrete...

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...

Urban roadways and public spaces are major fields of application for road concrete in France. Specialised contracting firms have gradually refined the finishes, skills and techniques to provide an extensive range of decorative concrete models. A collaborative process known as VECU (French acronym for roadways, public spaces and urban development...

New legislation for improving accessibility to buses by people and especially disabled people led to the modification of bus platforms and particularly the kerbs at these platforms. Buses should be able to approach quite close to these platforms. This depends on the design of the bus stop area. The dimensions...

There is significant uncertainty and variation in the environmental life cycle assessment of pavements. Uncertainty and scenario variation should be sufficiently accounted in the comparative life cycle assessment in order to increase the confidence on decisions regarding the environmental implications of alternative pavement systems. In this paper we first present...

The paper illustrates, on the grounds of Poland’s 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...
