This paper describes a new joint, in rigid pavement , employing octagonal slabs who link with square slabs, the angle between the sides of the octagonal slabs, have at each corner , 135 degrees. in any corner of this octagon, between the edges of the pavement. The square slab who...
Photometric Characterisation of the Concrete Pavement in the Sinard Tunnel Favouring a Sustainable Concrete Pavement
The Sinard tunnel (length 980 metres), located South of Grenoble, is one of the few in France to have a concrete pavement. Once the tunnel was opened to traffic, in 2007, a campaign of photometric measurements was initiated to follow the evolution of photometric characteristics of the concrete pavement with...
Concrete Pavements for Dedicated Lanes for Buses
A great number of cities, looking for a sustainable and attractive urban transport regarding speed, reliability and service quality, are promoting public transport on dedicated lanes, either with railway systems or with buses. Due to their versatility and lower construction and operating costs, buses become more interesting than railway systems....
Modern Concrete Safety Barriers State of the Art 2010
Since the beginning of the development of concrete vehicle restraint systems in the 1960s with the introduction of the New Jersey profile in the United States quite a lot of efforts have been taken by researchers, authorities and industry worldwide to raise effectiveness and safety of concrete and steel barriers....
High Performance Cementitious Material (HPCM) a Long-Life Wearing Course for Heavy Duty Pavement
This paper presents an on-going, international research project, aimed at demonstrating the valid-ity of an innovative concept of long-life wearing course. The High-Performance Cementitious Mate-rial (HPCM) consists of an ultra-thin, 8 mm layer of Ultra-High Performance Fibre Reinforced Mor-tar, in which hard, non-polishing aggregates are embedded. This composite material is...
Execution of Concrete Pavements with a Fixed Moulds System the Experience of Portuguese Air Force
Portuguese Air Force (PoAF) has, over the years, adopted the above mentioned solution for the construction of concrete pavements in their operational areas, considering this is the best suited technical and economical option to build and carry out aeronautical pavements in a successful way. Although this solution has higher initial...
The Cyclo-Pedestrian Footbridge Over the Former L160 Railway Line in Brussels
The cyclo-pedestrian footbridge built at the beginning of 2009 over the former L160 railway line in Brussels (Auderghem) consists of a 58-metre long reinforced concrete slab (cross-section 4.50m x 0.30m), chaotically supported by 37 wooden stilts (Douglas Fir). Its horizontal stability is ensured by two concrete abutments; the stilts, ball-and-socket...
Roundabouts in Continuously Reinforced Concrete Design Construction
In Belgium, as in many European countries, traffic at major junctions is managed increasingly by constructing right-of-way roundabouts, which allow safer and smoother traffic flow. The intense heavy traffic at these roundabouts induces extreme stresses in the pavement, both as a result of centrifugal forces as well as the overloading...
Concrete Bus Lanes
Cities worldwide are facing problems of traffic congestion in their centres and suburban areas as well as on access roads. In densely populated countries like Belgium and the Netherlands this phenomenon also occurs on roads linking cities. Because of these mobility problems and the serious impact on the environment, decision...
Concrete Pavements in the Province of Almeria the Experience of the Diputación De Almería
The Diputación de Almería has approved biannual plans to improve agricultural and rural tracks and roads in the region, which are financed by, in addition to the Diputación de Almería, also by the European Union, the Junta de Andalucía and the municipalities in the zone. Improving these trails in general...
Continuously Reinforced Concrete Pavement in Marchena Bypass
Marchena bypass is a ring road which will run in the south of Marchena, in Sevilles province. Its total length is 7,6 km, and its cross section is 10 m in the coronation of the pavement. After deciding the placement of the concrete pavement, the specific type chosen was the...
Contribution of Concrete Pavements to the Safety of Tunnels in Case of Fire
A number of tunnel fires in Europe have demonstrated the need for appropriate choice of materials for tunnel construction to ensure high safety and reliable availability to traffic. In case of fire, an incombustible and non-toxic road pavement, as it is a concrete one, contributes to the safety of people...
