Skid resistance of a pavement surface is important for safety. Therefore the surface of a concrete pavement must have a roughness suitable for a high skid resistance but also for a low noise emission. These surface properties must be as durable as possible. In Germany there are various possible ways...
Skid Resistance of Concrete Pavement Surfaces Practical Experience in Germany
Experiences from Construction of Concrete Motorways in Poland
During last years more than hundred kilometres of concrete motorways at the southwest part of Poland were modernised and newly constructed. In the frame of modernisation the old existing concrete pavements, constructed in 30's of last century, were broken-up and the crushed concrete was re-used in new concrete pavement. Newly...
Inlay in Continuous Reinforced Concrete on the A10 Brussels – Oostende at Ternat
Between September and November 2002, an inlay in continuous reinforced concrete was constructed on the A10 motorway between Groot-Bijgaarden and Ternat. The main components of the section of road are concrete slabs that are overlaid with asphalt surfacing. The work was performed in the shortest possible period, during which the...
Investigation of Maintenance Needs For In-Service Concrete Pavements
Given the large number of concrete pavements that have performed well over time and lived up to prior expectations, as well as the knowledge that is now available regarding the reasons for failure in certain concrete constructions, it should be possible to carry out an evaluation of these pavement types....
Test Sections of Rigid and Flexible Pavements
The number of heavy vehicles in the Swedish road network is continuing to grow, and more rigid types of pavements are being used to withstand the loads. During the 1980s only asphalt pavements were used in Sweden and damage occurred on many roads with large traffic volumes. The Swedish National...
Joints in Concrete Roads
Concrete has been used as a construction material for road pavements for many years. Over the last 40 years, the world has seen a major program of motorway and trunk road constructions. The increase in the amount and individual weight of vehicular traffic has made increasing demands on the performance...
Determination of a Dedicated Concrete Pavement Network Using Probabilistic Life-Cycle Cost Analysis
In 2001, the Québec Ministry of Transportation (MTQ), in Canada, adopted a policy subdividing the existing pavement network into dedicated concrete and asphalt networks. This paper presents the methodology used for determining these respective dedicated networks using probabilistic Life Cycle Cost Analysis (LCCA). Sixteen (16) different combinations of Average Annual...
Crack Control in Liquid Tight Constructions
In Western Europe the demand for a crack-free structure is not uncommon. Due to environmental reasons more and more (concrete) structures are built to prevent toxic liquids from leakage trough the structure to the subsoil and groundwater. These structures can be found for instance in the chemical industry, petrol stations,...
Some Physical Properties of Roller Compacted Concretes Used in Road Pavement Applications
Some physical test results available in the literature on Roller Compacted Concrete (RCC) were evaluated. Most of the physical properties of RCCs such as drying shrinkage, frost resistance, abrasion, and fatigue are similar to those of conventional concrete with the same water-cement ratio. Since RCC is a zero slump concrete...
Remarkable Belgian Projects Using Coloured Exposed Aggregate Concrete Surfaces
The use of coloured exposed aggregate concrete in public spaces has made considerable progress in Belgium. As such, urban planners have become aware of the architectural value of this technique. The variety of shapes, colours and textures combined with the well-known advantages of concrete such as resistance and durability explain...
Concrete Safety Barrier in the UK
This paper describes the usage of concrete safety barrier on high speed roads in the UK, drawing on experiences gained over the 10 years since their introduction, and the enhancements and improvements developed in this time. The paper is primarily concerned with in-situ slipformed concrete safety barrier and comments on...
Roller Compacted Concrete
Roller concrete has been adopted from dam-building technology, where it is used as a rapidly constructed and durable solid concrete. In road construction, roller compacted concrete is predominantly used in foundations, as a supporting layer. For surfacing or as a layer of surfacing. Some applications in Belgium are discussed. This...
