The approach to using concrete as a material to form a Barrier is almost as ancient as the material itself. Through significant effort and investment, Britpave has successfully driven the directive to install concrete barrier on all motorways in the UK that carry more than 25000 vehicles per day. The...

The pavement of the so-called “recycling centers” in the cities requires special attention because of their special conditions. On the one hand, the pavement has to have adequate impermeability against different residues that could have potential contaminants that could leach into the subsoil. On the other hand, they should fulfill...

In this study, properties of concrete used in a pavement construction in a tunneling project in Istanbul, are investigated. The properties of materials and mixture designs of the concrete are investigated by trial mixtures in the laboratory and ready mixed concrete plant. Fresh concrete properties such as workability, mechanical and...

The Federal Aviation Administration’s (FAA) National Airport Pavement Test Facility (NAPTF) is located at the William J. Hughes Technical Center, Atlantic City International Airport, New Jersey. The primary objective of the tests performed at the NAPTF is to generate full-scale pavement performance and response data for development and verification of...

Usually pavements for heavy load service are constructed with double reinforced concrete. Mostly their thickness is about 40 cm and – beside the high costs – there are structural problems with the placing and the design of joints, if unwanted cracks and steel corrosion should be avoided. In addi-tion to...

Depending on the prevailing material and energy prices, concrete roads can be made more cost-effective than asphalt roads. However, to provide a truly sustainable solution, it is necessary to reduce the energy consumption associated with the production and maintenance of concrete roads, as well as to minimise their construction /...

This paper describes a new joint, in rigid pavement , employing octagonal slabs who link with square slabs, the angle between the sides of the octagonal slabs, have at each corner , 135 degrees. in any corner of this octagon, between the edges of the pavement. The square slab who...

The Sinard tunnel (length 980 metres), located South of Grenoble, is one of the few in France to have a concrete pavement. Once the tunnel was opened to traffic, in 2007, a campaign of photometric measurements was initiated to follow the evolution of photometric characteristics of the concrete pavement with...

A great number of cities, looking for a sustainable and attractive urban transport regarding speed, reliability and service quality, are promoting public transport on dedicated lanes, either with railway systems or with buses. Due to their versatility and lower construction and operating costs, buses become more interesting than railway systems....

Since the beginning of the development of concrete vehicle restraint systems in the 1960s with the introduction of the New Jersey profile in the United States quite a lot of efforts have been taken by researchers, authorities and industry worldwide to raise effectiveness and safety of concrete and steel barriers....

This paper presents an on-going, international research project, aimed at demonstrating the valid-ity of an innovative concept of long-life wearing course. The High-Performance Cementitious Mate-rial (HPCM) consists of an ultra-thin, 8 mm layer of Ultra-High Performance Fibre Reinforced Mor-tar, in which hard, non-polishing aggregates are embedded. This composite material is...

Portuguese Air Force (PoAF) has, over the years, adopted the above mentioned solution for the construction of concrete pavements in their operational areas, considering this is the best suited technical and economical option to build and carry out aeronautical pavements in a successful way. Although this solution has higher initial...
