The concrete construction method is predominantly used in Austria for the high-rank road network (motorways, expressways) with heavy traffic and / or a high percentage of heavy vehicles. Re-cently, concrete pavements are also used in case of low traffic loads (track lanes, concrete paving blocks) and for roundabouts. This contribution...
Permeability Behaviour of Recycled SFRC and Its Implications in the Durability Resistance of Rigid Pavements
Recycled steel fibres obtained from post-consumer tyres can be used as reinforcement for concrete pavements. They can improve the mechanical behaviour when compared to plain concrete, especially the post-cracking compressive, tensile and flexural strengths. Recycled fibres may also enhance shrinkage, fatigue and impact performance. However, it is important to understand...
Concrete Roundabouts in Switzerland
In Switzerland concrete pavements for roundabouts are considered a suitable and cost effective and above all a durable solution. The service life is estimated to be 40 to 50 years, what can only be achieved by concrete pavements.
The Design of URC, Heavy Duty Slip-Formed Concrete Pavement for a Port Environment
The design of heavy duty pavements for ports and harbours is becoming an important concrete pavement application. This paper summarises Ove Arup & Partners experience in completing the design of heavy-duty container port pavements. The paper outlines a practical set of calculations complete with a standard, jointed unreinforced concrete (URC),...
Three Year Performance of Continuously Reinforced Concrete Pavement with Glass Fibre Reinforced Polymer Bars
The first continuous reinforced concrete pavement (CRCP) using steel bars as reinforcement in Canada was constructed in the province of Québec in 2000. At that time, Project Engineers and experts tried to adapt the design of this type of concrete pavement used in other countries to the severe wet-freeze climate...
Fibremix Concrete for Road and Industrial Pavements
The paper deals with the development and application of fibre/concrete mix in general and specifically with the detailed design and execution for highway service stations and container terminals. It includes empirical evidence for the maximum size of concrete slabs without construction joints and the risks of cracks from dilatation or...
The Ekkersrijt Sustainable Roundabout Construction (A50)
At the exits and especially the entrances of Ekkersrijt in the Ring of Eindhoven (a part of the A50) is a problematic situation. Close to these entrances and exits there is a concrete elements factory (Betonson) which is producing elements with big dimensions. That means not only heavy loads (which...
Environmentally Friendly and Durable Concrete Barrier (A73)
A safe and durable concrete barrier has been built on the A73 in the southern part of The Netherlands (Province of Limburg). The decision to install this barrier was based on consumer-focused networking. The benefits of concrete barriers were illustrated during the networking process, including the prevention of break-through and...
Durable Futuristic Roundabout in the City of Eindhoven, the Netherlands
The main traffic entrance to the city of Eindhoven is the connection with the surrounding A2 Highway. This entrance of the city is a large two lane roundabout with a diameter of 97m.A lot of heavy trucks use this roundabout. The asphalt pavements of this roundabout showed severe rutting, cracks...
Modern SFHC Super Fast Hardening Concrete Repair System for Airfields and Roads, Based on Special Cement for Infrastructure Projects
The importance of fast traffic area repairs is increasing. For roads and airfield service areas a specific fast repair system has been developed to satisfy the demand. This system uses standard methods of ready-mixed concrete and is appropriate if a few additional requirements are taken into account. The placing is...
A Bonded Concrete Overlay in An Urban Boulevard in Calvià (Mallorca, Spain)
The Boulevard of Peguera, placed in the municipality of Calviá (Mallorca, Spain), is the main commercial axis of the town and, for this reason, it supports an important traffic compared with other urban roads, around 100 heavy vehicles per day. At the beginning of 2008, the Council of Calviá proposed...
The CRCP/BGBA Composite Structure for the Bassens Building Site (Gironde Department in France)
The continuously reinforced concrete pavement (CRCP)/bituminous-bound graded aggregates (BBGA) composite structure has been chosen as a base solution for the conversion and development road works carried out in the industrial harbour area of Bassens in the Bordeaux Suburb (France). This structure, which was suggested by the Bordeaux City Administration Engineering...
