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 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...
Belgian Specifications for Freeze-Thaw-Resistant Pavement Concrete
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...
Precast Electrified Roadway Pavement Systems using Engineered Cementitious Composites
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...
Mixture Quality and Cost-Benefit Analysis of Concrete Overlay Application in Lithuania Pavements
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...
Accelerated Full Scale Test on Prefabricated Conrete Slab Pavement for Electrical Supply by Induction of Urban Transport Systems
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 in the Velodrome of San Vicente Del Raspeig Alicante Spain
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...
Importance of Correct Dowel Positions in Transversal Joints of Rigid Pavements
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...
Surface Grinding Concrete Pavements
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...
Road Safety and Surface Durability Aspects on Hungarian Cement Concrete Pavements
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...
Optimal Pore Distribution of Porous Concrete Pavers Aggregate
Concrete pavers are often used for construction of urban area roads as they offer both easy and fast construction as well as high aesthetical value. Although noise reduction is also very important in urban areas, research focusing on low noise concrete pavers is still rare. This paper illustrates a study...
Failures of Concrete Slit Drains Caused by Negative Effect of their Erroneous Integration Into Surrounding Multi-Layer Road Systems
Concrete slit drains (also known as slot drains see fig. 1,2) are being used for the draining of highways and roads, as well as for large handling and parking areas. Recently, this system of drainage has become increasingly applied, which does, however, bring with it an increased incidence of...
