Conf. Paper (EUPAVE)

The section of the E403 (A17) motorway between Bruges and Kortrijk was built in continuously reinforced concrete in the early nineteen eighties. The construction work was carried out in four phases with substantial differences between the phases with respect to the width of the pavement, the sub-base and the position...

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...

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...

The paper describes an experimental study concerning the use of hydraulically bound mixtures for roads and highways foundations, with the aggregate skeleton fully composed by industrial by-products, as foundry sands and steel slags, used with three different proportions. The laboratory investigation involved a preliminary study of the physical-geotechnical properties of...

Long-life concrete pavements require less frequent repair, rehabilitation, and reconstruction, and therefore contribute to improving highway safety and mitigating congestion. Experience with these pavements, including examples of concrete pavements that have remained in service for more than 35 years. CRCP set out to offer the market a new alternative in...

In 2006, a group of highway agency and paving industry representatives from the USA visited Europe in search of current practices for the design, construction, maintenance, and rehabilitation of concrete pavements. In every country visited, examples of exposed aggregate concrete were demonstrated. While not a new discovery, the discussions did...

Due to the magnitude of the project, its characteristics, and the economic and cultural development of the region where it settles, the construction of the Rosario – Cordoba Highway represents an emblematic project of the road activity in Argentina. A singularity of this motorway is that it has been built...

In order to extend the lifetime of concrete roads for many years, it is very important to secure a proper maintenance. Loosely embedded slabs, for example, should be stabilized and, if necessary, jacked in an early stadium in order to prevent further damage of these and the bordering slabs. The...

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...

Depending on the prevailing material and energy prices, concrete roads can be made more cost-effective than asphalt roads. However, to provide a truly sustainable solution, it is necessary to reduce the energy consumption associated with the production and maintenance of concrete roads, as well as to minimise their construction /...

World rice production reaches 662 million tons per year. The husks represent 20% of this amount and when burned, 20% of this byproduct is transformed into rice husk ash (RHA). In general, there is not an environmental management policy concerning this residue. Roller compacted concrete (RCC) is a material which...

The Sevilla – Cádiz motorway was the first one in Spain where a concrete pavement was constructed with a slip-form paver. It was opened to traffic in 1971. Shortly, longitudinal cracks appeared, deemed to the presence of plastic soils in the subgrade. Sometimes these craks were several centimetres wide. It...
