In 2010 Houben has published a paper on the modelling of the process of cracking at transverse joints in jointed plain concrete pavements (JPCP). Houben uses equations from the standard Eurocode 2 for the time-dependent concrete properties and considers the thermal deformation and the shrinkage (drying and autogenous) for different...

Current pavement design guides for Jointed Plain Concrete Pavements define one critical location at the mid-slab edge and assume that damage accumulates linearly and can be described via S-N curves. More recently, experiments have shown that damage does not accumulate linearly and a pronounced stress range effect exists. These two...

The ability to spatially map the stiffness of the foundation layers under concrete pavements with intelligent compaction has created a need to define limits on the allowable stiffness variations in a given construction area as well as the maximum size of a non-complaint area which does not require remedial action....

In 2009 the Dutch Parliament amended special laws to speed up road widening projects. This situation opened possibilities for sustainable concrete pavements needing less maintenance, especially for the right-hand lane that takes the heavy traffic. This paper presents the results of a study carried out in 2009, by a working...

The record of the first concrete road construction in India dates back to 1914. However, till the end of eighties, cement was a scarce commodity in India; therefore, concrete road construction was relegated to the background. After liberalization of cement market, concrete roads staged a comeback and in the nineties...

The performance of road surface is the first and main indicator of information of the condition of the road. For some singular damages in-depth analysis is not necessary; for these an instruction for an appropriate maintenance measure is possible. However, by area-wide recurrent or systematic damages causes are important in...

In 1999, a 60 000 m2 large concrete pavement was completed in a Swedish harbour. The largest part of the area consisted of 200-210 mm thick plain jointed concrete pavement (PJCP) overlaying an old asphalt pavement. The design was based on certain prerequisite concerning traffic loads, i.e., axle loads and...

The advantages of prefabrication and precasting are well known in the building industry: a short building-time, efficient use of materials, optimum quality control, financially appealing and sophisticated logistics. In residential, commercial and industrial building in the Netherlands, the use of prefabrication is common practice. It would be logical to assume...

On 13 December 1967, the “E5” Partnership was established in Belgium with the objective of constructing the Brussels-Liège motorway. This was the missing piece in Belgium of the E5 European route, which extends from London over Calais-Jabbeke, Brussels, Liège, Cologne, Frankfurt and Vienna to Ankara. Later, the name E5 was...

Since the 2001 were constructed in Slovakia three highway tunnels with cement concrete pavements. This paper presents the Technical recommendation – the concrete pavement design method used for the design and calculation of pavement structures. According the different “climate conditions” in tunnels (concerning temperature gradients in slab), there are in...

“Photocatalytic” materials are discussed for various applications in building technology ranging from de-soiling to de-polluting applications. However most of the efficiency proofs are derived from indirect laboratory scale tests. Italcementi Group has developed a range of cement-based products based on the TX Active? concept demonstrating both photocatalytic activity and performances...

This document describes the design and construction of the concrete whitetopping repair of a severely distressed pavement of a road section at a regional road intersection. In the past, repair of this road section with asphalt overlays repeatedly failed to withstand the severe shear loading to which the pavement is...
