This Presentation on Roller Compacted Concrete (RCC) experience in the U.S.A outlines: What is RCC and RCCP? Does it have a place on Australian projects? Is RCC still Slipformed Concrete’s Ugly sister? Application Examples of RCCP – Roads – Industrial Why is North America leading the world?

With more concrete pavements being constructed over soft soil foundations, the use of coal combustion products, such as furnace (bottom) ash, to provide bridging of soft areas and reduced construction risk by being able to be placed insitu in wet weather, becomes more critical. The use of such materials in...

Bordeaux, Clermont-Ferrand, Caen, Grenoble, Lille, Lyon, Marseille, Montpellier, Nancy, Nantes, Nice, Orléans, Rouen, Saint-Étienne, Strasbourg, Paris….

Using appropriate security barriers for directing the traffic in urban areas, close to downtown, shopping centers, protecting working zones in urban areas in general, and separating traffic, is essential for the safety of different traffic users. The traffic flow at industrial, commercial and public areas is easily managed by using...

One of the main advantages of pervious concrete is its ability to drain water easily. Moreover, ear-lier studies on pervious concrete have shown that it can be designed to perform well in freeze-thaw regions. Bridge superstructures placed in regions where the temperature during winter time varies around freezing point are...

Our modern world is characterised by traffic, the traffic of goods and/or information. Both will increase in the near future. Further there will be a strong increase in communication technology which will influence the individual traffic as well. At the same time all kinds of emissions caused either by the...

A 21 km long motorway is planned to be constructed through the western suburban of Stockholm. The motorway will mainly be localized in tunnels with a total length of 18 km. The intention is that the tunnel pavement shall be constructed as a jointed plain concrete pavement (JPCP) resting on...

Many concrete pavement mixtures in the US are proportioned based on recipes that have been used before, or on prescriptive specifications. As budgets grow tighter and increasing attention is being paid to sustainability metrics, greater attention is beginning to be focused on making mixtures that are more efficient in their...

On the initiative of concrete road professionals on the one hand – the French cement industry represented by its trade association CIMBETON and concrete pavement construction companies represented by the trade association SPECBEA – and the French road administration represented by SÉTRA on the other hand, a new concrete pavement...

Calcium aluminate based mortars have been widely used for fast setting repair applications. This article will present the laboratory work that was conducted to repair an existing concrete road in Istanbul. The main damage mechanism was both abrasion and frost damage; the maximum time that the road can be closed...

For networks owners, like the French national gas utility, it is essential to ensure a rapid access to their installations, even with a simple pick, for normal or emergency maintenance matters. Modular concrete pavements were developed during the last years for that purpose. In order to keep their stability, the...
