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...

The technique of double-layered concrete or two-lift paving is applied either to obtain a high-quality top layer, to use lower quality materials in the lower lift, or for both reasons at the same time. In Europe this technique is commonly applied in Austria where a typical motorway is built with...

Congestion on German roads increases permanently from year to year. According to the latest prognosis an end to the traffic increase – especially with regard to heavy traffic – is not in sight. At the same time the Federal government, the German states and communities lack capital for new infrastructure...

The first continuous reinforced concrete pavement (CRCP) using steel bars as reinforcement in Canada was constructed in the province of Québec in 2000. At that time, Project Engineers and experts tried to adapt the design of this type of concrete pavement used in other countries to the severe wet-freeze climate...

Since the beginning of the development of concrete vehicle restraint systems in the 1960s with the introduction of the New Jersey profile in the United States quite a lot of efforts have been taken by researchers, authorities and industry worldwide to raise effectiveness and safety of concrete and steel barriers....

This paper reports research concerning the excavatability assessment of controlled low-strength materials for trenches with a pick, thanks to the proposal of a laboratory and a field test. Attention is specially focused on air-entrained mortars and very lean concretes. The scientific approach is first presented. Then details and results on...
