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...
Pavement Design Procedures for New Construction and Rehabilitation with Overlay
The first part of the paper deals with the designing of rigid pavements by means of FEM. The NE10-SOILIN program uses the NE-10 finite elements composed of subelement 2D NE-10-M (tetragonal element), subelement 3D NE-I013RJCK and subsoil element. It models the Midlins slab placed on a generally multilayer structure. Under...
Technical Conditions for Completely Using the Advantages of Concrete Pavements
It is immanent for concrete pavements not to get plastic deformations and therefore concrete pavements are especially suitable for heavy traffic roads. However, pavement performance depends from avoiding of some structural faults.
Use of Fast Track Concrete Paving for Restoration Work
Many roads in Belgium, both main and secondary, are in need of modernisation or repairs. The surface area of old concrete pavements that are thus concerned on an annual basis is estimated at approximately half a million m2 . The inconvenience to the user caused by this type of work...
Method to Establish the Porosity – Depth Distribution of Porous Concrete Pavements Using Cylindrical 100 Cml Cores Samples
The paper deals with a low cost method to establish the porosity - depth distribution in porous concrete pavement using cylindrical 100cm cores samples. The outcome is a graph representing the porosity in function of the depth below the surface. The method is non destructive with regard to the core...
Sand-Concrete Pavements Gainful Use of Local Materials
To complete the road between La Teste town and the famous , the Gironde Regional Council use the knowledge and experience requied during the national research and development project on sand concrete named SABLOCRETE to build a sand concrete slab pavement structure along 3,5 kilometres. The owners and engineers of...
