The use of continuously reinforced concrete pavements (CRCP) is well spread in Belgium, mainly because of the confidence in its durability. It is used frequently on Belgian motorways and also on other heavily trafficked roads. The behaviour of CRCP is influenced by a number of specific characteristics such as the...

The AP-4 motorway connecting Seville with Cadiz in southern Spain was opened to traffic in 1971. About half its length has a concrete pavement designed in accordance with the Californian approach prevailing at that period (plain concrete pavement with undowelled joints, on a cement treated base). Pavements with asphalt concrete...

There is great potential to use the large open space of pavement structures, equipped with an embedded pipe network, in conjunction with a heat pump, to provide heating and cooling for adjacent buildings, e.g. airport terminals, shopping centres etc, here termed a Pavement Source Heat Pump (PSHP). Due to the...

In order to rehabilitate non-dowelled secondary concrete slab roads or to reduce noise caused by faulting slabs, it is necessary to have a clear understanding of their stability.. Faulting, pumping and the presence of voids must be investigated, and appropriate stabilization measures must be taken. Different investigation techniques are applied...

The paper deals with the development and application of fibre/concrete mix in general and specifically with the detailed design and execution for highway service stations and container terminals. It includes empirical evidence for the maximum size of concrete slabs without construction joints and the risks of cracks from dilatation or...

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...

While cement stabilisation has been an alternate for pavement construction for many years, it is in the last 15 years that there have been significant changes in our knowledge and ability to build long lasting cement stabilised pavements. These developments have been as a result of significant improvements in the...

Almost all jointed concrete pavements in the Netherlands, varying from low volume country roads to dual carriage motorways, are designed with the ‘Vencon 1.0’ program. The program needed to be upgraded to the Windows operating system. The upgrade also gave an opportunity to reconsider the design models of the old...

The pavement is the main and the most important component of a road. Pavements play a major role in the construction cost, maintenance and rehabilitation, traffic quality, vehicle and user costs. They are mainly divided into two types: asphalt concrete and cement concrete. For decision making in choosing the pavement...

Since the late 80ies in the Netherlands more and more cross-sections are constructed as roundabouts in stead of a cross section with traffic-lights. The pavements and prefabricated elements suffer from heavy traffic-loads and lots of maintenance was required. Therefore the last years it is investigated how sustainable roundabouts could reduce...

The rehabilitation of the Ring Road of the city of Antwerp is the largest and most discussed road construction project undertaken in Belgium within the last decades. The Antwerp Ring Road is one of the most trafficked urban freeways of European importance. Six radial freeways are tying into it and...

The properties of concrete mixes produced by replacing the coarse aggregates by milled bituminous materials of the same grading are studied in the laboratory. The milled bituminous material used comes from reclaimed asphalt concrete produced in road maintenance works. The properties investigated are compressive and flexural strength, modulus of elasticity,...
