Pavement Type Selection: What is the Ideal Process?

Highways Members Only

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...

Concrete Pavement Contribution to Fire Safety in Road Tunnels

Highways Members Only

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...

Movement of Unanchored Terminus of Continuously Reinforced Concrete Pavement

Highways Members Only

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...

Continuously Reinforced Concrete Pavement with Asphalt Top Layer or Surface Texture from Diamond Grinding- the Trial Site on Motorway A94

Highways Members Only

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....

Concrete in Roundabout Design

Highways Members Only

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...

CRCP with Ground Texture – Experiences and Results of the Geseke Access Road Pilot Project

Highways Members Only

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...

Concrete Pavement on Bicycle Trails

Highways Members Only

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...

Optimization of the Recycling of Concrete in Concrete Application to an Airport Slab

Airports Members Only

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...

Durable and Sustainable Concrete Pavements on Public Private Partnership Projects

Highways Members Only

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...

Eupave Symposium on Concrete Roads – Prague 2014 Urban Roads Session

Highways Members Only

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...

Road and Railway Tunnels the Concrete Solution for Improving Passenger Safety and Emergency Response

Highways, Trackslabs Members Only

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

Highways Members Only

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,...
