This article describes the behaviour after 17 years of service of the test sections constructed in 1979 on State road N 4 in the Belgian province of Namur. The object of this experiment, is to compare various types of contraction joint on the same site and under the same conditions...
Pavement Performance and Evaluation of a Four Years Old Concrete Road – Study of a Concrete Section of the E6 Road at Falkenberg in Sweden
Interest in concrete roads has increased in Sweden in recent years. Contributory factors are the increased traffic loadings, which demand more rigid types of pavements, and the excellent resistance of concrete roads to wear from studded tyres. This conference paper describes the pavement performance of a four-years-old concrete road that...
Performance of Precast Prestressed Concrete Pavements Prestressed at Joints
The precast prestressed cornrele pavement (PPCP), which allows rapid execution of repair works such as these on intersections, is inasinglyuse1 these days. It contains many joints that conventionally take the form of dowel bars, which, however, are reported to be vuhierable to damage by rainwater seepage and other factors. To...
Roughness and Ride Quality of Airport Pavements
This paper describes a method for routinely evaluating airfield pavement surface roughness from an aircraft ride quality perspective. The method is designed to be as compatible as practical with existing pavement management system data collection and reporting processes. Ride quality has always been recognized as a major factor in a...
Use of Calcium Aluminate Cement in High Strength Concrete for Fast Repair of Old Concrete Slabs
The oxides present in the chemical compositioii of calcium aluminate cement, especially monocalciiim aluminates. is what gives the concrete manufactured with this type of cement its slow setting, quick hardening properties. The products generated during hydration of anhydrous phases in calcium aluminate cement. will depend on ambient conditions at the...
First Experience of Noise-Reducing Exposed Small Aggregate Concrete Surfaces in Japan
In Nagoya, Japan, for a national highway having a large-scale common duct set under the road, concrete pavement with transverse brooming has been adopted in order to ensure structurally durable pavements. However, because these roads are located in an urban area, demand for less noisy pavements has increased. Therefore, in...
Ushuaia’s New International Airport
The highest expression of engineering lies in those works which challenge nature and rise through a modified environment as a proof of human genius and perseverance. Ushuaia's new international is one of those titanic works, located in the Andean geography, next to the Beagle Channel, in the most southern city...
Bidding Procedure, Contract Award and Construction of the Motorway Al 5 between Cottbus-West and Forst (Germany)
The turnkey construction method can be very beneficial to an employer both during the bidding process and during construction. A turnkey road construction project was selected for the first time in Germany as the construction method for the A15 motorway between Cottbus-West and Forst. In order to alleviate backups within...
Further Improvement of the Durability of Concrete Pavements by using Higher Strengths
Road concrete in the thirties did not have a particularly high strength, but it grew over the years. Strength tests on cores, taken last year, show that the strength -compressive as well as the more important splitting tensile- of the old section and also of almost all new ones is...
Thin Steel Fiber Reinforced Concrete Overlays and Inlays
Between 1982 aiid 1989, 8 thin overlay test sections were constructed with a total surface area of 129.000 m2 . The relevant research project is carried out with a view to the necessary future renovation of part of the Belgium road network. All sections were built with 10 to 12...
A New Technique for Preckracking Materials Treated with Hydraulic Binders
Precracking techniques are used for materials treated with hydraulic binders in order to restrict the effect of shrinkage cracks on the pavement performance. After developing a precracking technique for port platform stwctures in 1984, Via france recently received and developed a new technique for road pavements. This technique applies to...
Cement Concrete Structures in the Design of Urban Roadways
Urban roadways represent considerable stakes from both the quantitative and qualitative standpoints, with the almost permanent concern today for integration with respect to the site and to users of public spaces. A non-exhaustive review of the trends in practices and tools available to designers, builders and managers of urban roadways...
