Roller compacted concrete (RCC) pavement has been used for decades in situations where repetitive heavy loads are applied and for large paved areas. These applications have included logging yards, ports, automobile manufacturing plants, and warehouse districts among other places. While these are appropriate applications for RCC pavement, there are many...
Skid Resistance Properties of Concrete Pavement Surfaces in Tunnels
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...
Environmental Product Declaration of Czech Cement
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...
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...
Recyclable High Volume Fly Ash Pavement Concrete Using Limestone Aggregate
Fly-ash is a pozzolanic material, so it can contribute to various properties, such as strength development at mature age. The strength development at early age, however, is significantly slow and may negatively affect traffic service. Early strength may be improved when limestone filler is mixed in fly-ash concrete. In addition,...
Photocatalytic Air Purifying Pavements in Belgium Where are We
The construction and rehabilitation of roads are more and more linked to the environmental impact of this road. Durability, noise and air quality become more and more important as design criteria. The choice of materials can influence the environmental impact of traffic and road infrastructure. In this respect, photocatalytic concrete...
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...
Influence of Test Specimen Compaction and Curing Condition for Pavement Cold Recycled Mixtures
Presently in most European countries the quality of cold recycling mixtures in pavement rehabilitation is proven by achieving required strength values (indirect tensile strength or compressive strength) and eventually by values of stiffness modulus (IT-CY test method). This empirical approach of quality assessment is quite simple, relatively fast in performance...
A Review of Mechanisms Associated with Premature Joint Deterioration in Concrete Pavements
Premature deterioration of sawn joints has been reported in some cold climate regions in the USA. This paper reviews the multiple mechanisms have been found to contribute to the deterioration. Laboratory and field investigations have shown that freezing and thawing of saturated concreted is a dominant factor. Magnesium and calcium...
