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...

This paper explains the basic concepts, history of studies and the results of the Life Cycle Assessment (LCA) of the Czech Cement and Environmental Product Declaration (EPD) of the Czech Cement. The Environmental Product Declaration is based on the method of life cycle assessment, which generally evaluates the impact on...

The results of the investigation concerning the loss of skid resistance on Austrian tunnel roads are presented in this poster as well as the results of trials to improve the skid resistance level in the laboratory. Best results were achieved through cleaning the road surface in the tunnel with tailor...

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...

The Belgian standard specifications contain a number of clear requirements for the composition of concrete mixtures and the properties of fresh and hardened concrete. It is generally known that water and air content have a substantial impact on the frost susceptibility of a concrete surface – the former in a...

The adoption of electric vehicles (EVs) remains low mainly because of its battery related problems, which include high cost, range limitation and weight. Electrified roadways, which allow EVs to charge while they are in operation (motion or stationary) by using Inductive Power Transfer, is a very innovative technology to overcome...

Heavy vehicles traffic flow and loads are increasing every year and influence faster degradation of asphalt pavement. A lot of money is expended on distressed pavement repair and rehabilitation, so sustainable pavement structure development is one of priority in Lithuania. Flexible (asphalt) pavement design lifetime is 20 years and often...

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...

A concrete cycle track was built in the velodrome of San Vicente del Raspeig, a town close to the Mediterranean Sea in the province of Alicante, in the South East part of Spain. This sport facility was opened in 2013. The cycle track is 7 m wide and 250 m...

Positions of dowels and tie bars in jointed unreinforced concrete pavements and the importance of their correct placement on pavement behaviour and lifespan was studied as a part of R&D project of Technology Agency of the Czech Republic No. TA02031195 and TE01020168. Laboratory concrete beams with in-built dowels in different...

The report outlines some of the perceptions and issues associated with Concrete roads, and asks if the process of Diamond Grinding is a viable solution to the refurbishment of worn concrete pavements. The paper outlines the process of Diamond Grinding for reconditioning structurally sound but worn concrete surfaces. Gives a...

The ratio of cement concrete pavements has increased in the Hungarian motorway network in the last decade, and it has appeared also in the local road network. There are 15 cement concrete pavement sections with different type in Hungary. Maintenance agencies need a simple methodology for calculating surface deterioration of...
