In spite of numerous cyclists (3.5 millions), until the seventies, the emphasis was in particular on the construction of motor roads and motorways. The cyclist was fairly vulnerable in this environment. From the eighties onward, a new vision appeared in the Flemish region: in and around conurbations, cycle track plans...
Concrete Pavements on Industrial and Port Areas the Belgian Experience
The relative improvement of the economic situation, the growing transport by trucks and the increasing use of containers have created an important need for durable pavements, with very low maintenance cost. Due to the rich Belgian experience with concrete roads, many companies prefer to use concrete for surfacing industrial and...
Appropriate Technology Concrete Pavement Trials in Zimbabwe
In 1985 four trial sections of two-lane concrete pavement were laid in Zimbabwe. The purpose was to provide a data base for the preparation of appropriate design and maintenance specifications, suitable for the conditions found over a large part of Africa, namely, good subgrades, moderate rainfall, large temperature variations, low...
Design of Low-Volume Concrete Roads. Tables Or Analytical Procedure?
This paper deals with the problem of thickness design of low-volume roads. It examines the possible use of tables of minimal thickness or analytical methods, especially developed for low-volume roads (as in France and Belgium). Attention has been paid to realise the influence of design factors, such as traffic and...
Concrete Setis a Functional and Rational Technique
The use of concrete setts in France has been growing for a decade, especially on urban roads. This technique, inspired by stone setts, but also by such precast concrete products as kerbs and gutters, very quickly generated needs: for design methods, for standardization of the product, for rules for use....
Urban Road Pavements the Landscaped Pavement Concrete
The new concept of the urban fabric is taking on extension and is testifying increasingly to the fact that in our cities the street is not a road. Cement concrete designs have been staying abreast of these developments and architectural concrete is just one of the significant outgrowths of these...
Precast Concrete Footway Paving Slabs That Resist Vehicular Overrun
This paper presents research into the design of square precast concrete paving flags ranging in plan size between 600 mm and 300 mm square. A design method for these paving flags overrun by vehicles is presented. The method shows that the existing test procedure underestimates the paving flag strength and...
The Design of Concrete Block Pavements For Urban Roads
This design method for concrete block road pavements applies to block pavements (under normal road traffic), consisting of rectangular paving blocks (thickness ~ 80 mm) in herringbone bond, 50 mm crushed sand bedding layer, eventually an unbound base, and a sand sub-base. The design criterion for such pavements is rutting....
Design Charts For Small Element Precast Concrete Slab Pavements Using a Combined Finite Element Westergaard Approach
Small element precast concrete slab pavements through their use in urban areas where vehicular over-run is predominant have suffered severe failures which incurred a substantial public expenditure for their maintenance in the UK. This has created a need for the development of a rational design method that would lead to...
The Passage of State Roads Through Built-Up Areas. Applications of Concrete Block Pavements
In the eighties, a campaign was set up in Belgium in view of the rearrangement of the state road sections which are passing through built-up areas. These projects were meant to improve the road safety and the viability along these cross town links. Efforts were made to come to a...
Superplasticised Concrete For Urban Paving
Concrete made with a superplasticiser has been used in Germany in the field of paving since the middle of the seventies. If these concretes of high workability show a high strength at a young age, they are called high early strength. These concretes can be subjected to high loading on...
Characterization by Means of Some Fracture Mechanics Parameters of the Concrete Pavement of the By-Pass Between Al and A2 Italian Highway
This work reports the results obtained with the three point bend tests (TPBT) carried out on beams made up of the concrete used for the construction of a by-pass highway and, by comparison, of medium (50 N/mm2) and high strength (98 N/mm 2) laboratory concretes. Typical parameters of fracture mechanics,...
