Contractor VBG NV from Heusden – Zolder started the execution of the above-mentioned site in August 2005 for an amount of 2 million EUR. It concerned large-scale structural maintenance: the repair of the longitudinal joint between the hard shoulder and the right-hand lane (continuous reinforced concrete) had been necessary for...

In this paper a new design method of plain concrete pavements without bond to the subgrade is presented. For the first time, stresses resulting from environmental conditions will be considered in a realistic way in addition to stresses due to live loads. The basis of this new design method is...

The composite pavement concept can be described as an association of bituminous layers or modular elements with cement concrete. The desired objective is the association of two or more layers of a different nature in such a way that the specific advantages of both types can be profited from thus...

In many countries the Falling Weight Deflectometer (FWD) is used to assess bearing capacity and thereby the structural condition of concrete roads. Due to the fact that the FWD is a stationary measuring system it can be used only for object related assessment of bearing capacity, but not for network-level...

The world-wide debate on suitable economic measures to improve mobility and energy efficiency has also led to the development of new and innovative construction materials and methods as a way of solving the problem of how to pave roads and trafficked areas economically. One such innovation is paver-compacted concrete, or...

The objective of the concrete pavement construction design of the main access streets to all Paranagua Port Terminals was to improve the traffic of trucks which transport goods being imported into and exported out of Brazil. Concrete pavement was the final engineering design chosen for this job due to the...

In the technology of the Roller Compacted Concrete (RCC) for pavement, various types of aggregations are used classically as aggregates, such as the crushed and the rolled aggregates limestone and siliceous, giving concretes with a relative density in the order of 2200 to 2300 kg/m3. In the present work, we...

Drainage concrete on the base of cement with BD10 admixture was analyzed in our research. The paper presents components of mixture, experimental results of thaw and freezing tests and compression strength for drainage concrete. The specimens were fabricated in Poznan University of Technology laboratory. All specimens were prepared as drainage...

During last years more than hundred kilometres of concrete motorways at the southwest part of Poland were modernised and newly constructed. In the frame of modernisation the old existing concrete pavements, constructed in 30's of last century, were broken-up and the crushed concrete was re-used in new concrete pavement. Newly...

The purpose of this article is to provide the administration and the designers with an effective, workable flow-chart so that the quality of the road is priority number one and that the execution problems are manageable. Based on the experience during most recent jobs COPRO observed interesting evolutions and missing...

Road traffic in Germany is increasing steadily year after year and recent forecasts have predicted that it will continue to do so. At the same time, neither the German central government, the federal states nor the towns and cities have the funds required for new infrastructure projects and urgently needed...

Water-permeable paving is used to minimize the far-reaching adverse effects produced by sealing off the natural water balance. The risk of flooding during thunderstorms by water running off the surface or by overflow from sewer pipes is strongly reduced by the immediate absorption and subsequent storage of water in the...
