This paper examines the results of temperature and strain measurements obtained using strain gauges installed in the concrete pavement of the aircraft parking area of the "Marco Polo" international airport of Venice. The purpose was to control the design assumptions and models and to assess the long term behaviour of...
Temperature Effects on the Concrete Pavement of the Marco Polo Airport of Venice
European Concrete Pavement Trial Project in the USA
The State of Michigan in the United States of America constructed a trial project that incorporated highway pavement design features from Germany and Austria. The project considered a 25.4 cm unreinforced concrete pavement, over a 15.2 cm lean concrete base, over a 40.6 cm granular frost layer. The concrete pavement...

Concrete Structures Made of One Piece Lean Concrete Slabs French Experiments and Pavement Design – Future Developments
France has an extended experience in hydraulic binder treated materials: in semi-rigid structures, in cement concrete thick slabs, in lean concrete for concrete pavement subbase layers. It has permit-ted to establish a new and very competitive struc-ture: the lean concrete thick slab on a drainingcourse with or without tranverse joints.A...
Concrete Continuously Reinforced with Flat_ Slotted_ Galvanised Steel Strips. Experience of FLEXARM Reinforcements. French Road Network 1986-1989
The dream of concrete pavement constructors, to replace the conventional difficult-to-fix reinforce-ments, which require a considerable manual work-force, with a continuous bobbin-wound reinforce-ment, has today become a reality. The chosensolution was a weldable carbon steel, with an elas-ticlimitgreater than 700MPA, a rectangular cross-section 40 mm x 2 mm, slotted for...
Developments in Noise Redution of Concrete Roads in the Netherlands
In the Netherlands experiments have been performed recently :onceming noise reduction on concrete roads. Three pos-.ibilities are being investigated:I. Top layer of no-fines porous concrete.~. Surface of washed dense concrete.. Dense concrete with fine-grained epoxy surface treatment. noise emission level slightly higher than on porous asphalt,iut much less than on...
Long Term Performance and Economic Aspects of Concrete Roads in Austria
Austria has more than 30 years' experience in concrete road construction. Half of the approximately 650 km of motorways with a concrete pavement are more than 20 years old. 40/0have already been reconstructed, some 14% will have to be reconstructed within the next 5 to 10 years. The remainder is...
The Effect of Heavy Loads on the Stress Distribution at the Surface of a Crc Pavement
A continuosly reinforced concrete pavement has been laid in 1984 within the steel mill Sidmar near the city of Ghent in Belgium. This paper deals with the tests performed in 1987 on the pavement and the analysis of the results. A French device, called "Ovalimètre", made it possible to measure...
Correlation Between Research and Construction of Concrete Roads
During the past two decades, the practice-oriented research work done when concrete roads are built has lead to further development of slab construc-tion, to new solutions to individual constructio-nal problems, and to development of new cons-tructional methods. Based on existing research re-sults, more reliable statements can be made on thedegree...
High Strength Concrete For Highway Pavements Ano Bridge Decks
An accelerated road-wear simulator employed by Norcem for experimental testing of abrasion resistance of highway concrete pavements subjected to heavy traffic by studded tyres was set up at Slemmestad, Norway in 1985. By increasing concrete strength from 50 up to 120 MPa, the abrasion was reduced by roughly 60-70 %....
