The A76 is the corridor between the Ruhr area (Germany) and Antwerp (Belgium) in the southern part of the Netherlands. It was built in 1985. Because the asphalt pavement failed as a result of a geological fault in the subsurface, a CRCP with a toplayer of porous asphalt was chosen....

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...

Skid resistance properties of concrete pavement surfaces in tunnels are measured with the dynamic measuring device TRT on a regular basis in the Czech Republic. Measurements are usually carried out before and after putting the tunnel into operation and then approximately once a year; the skid resistance is also measured...

Since 2003, roundabouts in Switzerland have been built with concrete carriageways. Because space is at a premium due to the population density, the diameter of most roundabouts is less than 30 m. Roundabout carriageways with small diameters are subject to particularly high shear stress levels, which is why the choice...

On site pavement recycling with cement is the most sustainable restoration technique, by means of which a degraded pavement is transformed into a consistent and more homogeneous structure, using the road as a source of aggregates. Both bearing capacity and homogeneity are therefore considerably improved. Due to the absence of...

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...

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,...

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...

At the request of the cement and concrete industry, in 2012 the Alabama Department of Transportation (ALDOT) funded Auburn University and the University of Alabama to recommend updates to ALDOT’s Life Cycle Cost Analysis (LCCA) methods for comparing asphalt and concrete paving alternatives. Auburn was asked to address LCCA from...

Life Cycle Cost Analysis (LCCA) is an economic procedure used to compare competing pavement designs, over a defined analysis period, considering all significant costs expressed in equivalent present value dollars. Currently, most agencies apply a standard, policy set, rehabilitation schedule to all pavements based on “historical” performance. However, this can...

One of the main advantages of pervious concrete is its ability to drain water easily. Moreover, ear-lier studies on pervious concrete have shown that it can be designed to perform well in freeze-thaw regions. Bridge superstructures placed in regions where the temperature during winter time varies around freezing point are...

In a life cycle analysis a higher investment cost is justified by lower maintenance costs, less and fewer traffic flow intrusions, and a longer technical life. All these factors contribute to a reduction of the carbon footprint. To further improve the sustainability of PCC pavements the rolling resistance should be...
