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...
Structural Functional and Economic Analysis of Jointed Plain Concrete Pavements
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,...
Super Fast Concrete Repair System for Roads Airfields and Railways Based on a Special Cement for Infrastructure Projects
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...
Recent Research on PCC Pavements on Bridges in Czech Republic
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...
New Developments of Porous Concrete and First Experiences in Germany
Porous surfaces of cement concrete (OPB) or asphalt concrete (OPA) have a permanent transfer of rainwater and additionally noise reduction potential compared to the dense microstructure with exposed aggregates concrete. Pervious concrete test sections in the field of heavy-duty highways previously reported, however, do not have sufficient durability. Causes of...
Concrete Pavement Contribution to Fire Safety in Road Tunnels
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 Vecu Process for Roadways Public Spaces and Urban Development Projects a New Approach for Consolidating the State of the Art
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...
Progressive Composite Bridge Construction with Cement Concrete Pavement
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...
A New Road with a Micromilled Concrete Pavement and a Bridge Over the Esla River in Leon Spain
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...
Concrete Pavement Preservation Integrating Engineering Application and the Environment
Concrete Pavement Preservation (CPP) is a series of engineered techniques developed over the past 40 years to manage the rate of pavement deterioration in concrete streets, highways and airports. CPP is a non-overlay option used to repair areas of distress in concrete pavement without changing its grade. This rational, preventive...
First Experience of Diamond Grinding Concrete in Mexico
The surface condition of a pavement is a factor that may vary due to the influence of traffic and construction methods, and is a functional characteristic that impacts the road user considerably. For concrete pavements in good structural condition, diamond grinding can be a highly effective and economical choice for...
Pavement Type Selection What is the Ideal Process
Pavement type selection is often one of the more challenging and controversial decisions highway administrators face. The process involves weighing engineering factors such as materials, structural, and even long term performance against initial and life-cycle costs to help agencies decide between various pavement alternatives. Given the expenditure of significant public...
