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....

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....

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...

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 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...

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...

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...

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...

Marchena bypass is a ring road which will run in the south of Marchena, in Seville’s 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...

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...

Setting pavement requirements for a not well-defined and not expressly foreseen use, implies the need of anticipating the different options of utilization that they will have to resist along their useful life. In this paper, it deals with paving an area of more than 11,000 m2 with a polyvalent use:...

Polish Cement Association has been promoting roads with concrete pavement for ten-odd years. Providing local authorities with information on advantages of the concrete local roads is a very important field of action. Consistent organisation of conferences and seminars, publication of books and brochures have given measurable effects. In the past...
