At the exits and especially the entrances of Ekkersrijt in the Ring of Eindhoven (a part of the A50) is a problematic situation. Close to these entrances and exits there is a concrete elements factory (Betonson) which is producing elements with big dimensions. That means not only heavy loads (which...

Portuguese Air Force (PoAF) has, over the years, adopted the above mentioned solution for the construction of concrete pavements in their operational areas, considering this is the best suited technical and economical option to build and carry out aeronautical pavements in a successful way. Although this solution has higher initial...

Inerting of contaminated soils is a processing technique that prevents them from migrating pollutants affecting the environment. It is based on obtaining by mixing soil with special cement based binders, an array of physical and chemical properties that immobilizes the harmful chemicals preventing its bioavailability. As a technique of treatment...

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...

The task of calculating road pavements is an easy one. However, reaching the point of choosing a type of pavement one is confronted with many possible solutions. They can all meet to the technical terms, such as bearing capacity, safety and durability. The growing importance of sustainable building has added...

In this paper is given overview of mineral additives that are used to improve mechanical and durability properties of concrete used in concrete pavements. Use of mineral additives is possible in two different ways, as a cement additive during production and as a concrete additive during preparation. Mineral additives analyzed...
