Design

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...

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...

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...

This document describes the design and construction of the concrete pavement for the relatively steep access ramp bridge of the PEZA truck holding area of the Bale-Weil customs facility. The pavement design takes into account the expected change in usage after 2008 as a motorway offramp and harbour access route....

For several decades steel wire manufacturers produce steel fibres which can be mixed with concrete to improve its characteristics. FIBRICON® is a multi-fibre concrete – a combination of concrete and three types of fibres. The fibre mix consists of drawn or rolled steel fibres with profiled end hooks or anchors....

The concrete road technique has been used for many years for the creation or improvement of roads in land reparcelling project areas. The designs used for these roads have had to develop for a variety of reasons: 1. Vehicles are becoming increasingly heavy. Semi-trailer rigs carry crops directly from the...

CEN Technical Committee TC 227 is responsible for the European Standards dealing with road materials. As a part of its working programme, 33 standards have been prepared concerning materials for concrete pavements. Six of them deal with specifications for materials, functional properties of concrete pavements, dowels and joint sealants (hot...

“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...
