Conf. Paper (EUPAVE)

The paper illustrates, on the grounds of Poland’s case, the concrete roads network development in a jurisdiction dominated by asphalt roads. The author reviews typical drawbacks apparent when promoting concrete roads, and identifies several most arresting phenomena that have led to the current technological stalemate. The goal of the paper...

The precast concrete pavement (PCP) technology is gaining wider acceptance in the US for rapid repair and rehabilitation of concrete pavements as well as for heavily trafficked asphalt concrete intersections. Although the US PCP technology is of recent origin, with projects less than about 12 years old, many projects have...

Abrasion resistance and impermeability are vital in road concrete. In this experimental study the compressive strength, abrasion resistance and transport properties of the road concrete were investigated. In order to study transport properties, water sorptivity and depth of penetration of water under pressure were taken into consideration. For this purpose,...

In June 2006, GISA a Public Company, within the Department of Planning and Public Works of the Catalonian Regional Government, awarded CEDINSA the concession for the project of constructing and operating the projects of converting into a dual carriageway the stretch Vic-Ripoll of the C-17 highway. As a participant in...

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...

The fundamental goal behind any pavement design and construction project is to provide a system that will survive the predicted traffic and environment for the selected lifetime. Considerable effort is paid to the structural design of a pavement in order to reach that goal. On the other hand, the concrete...

Concrete, used in the production of highways and pavements, may deteriorate after many years of service, due to severe exposure conditions. Due to strategic and economic importance of such infrastructures, swift action for repair works is required. Repairs with conventional concrete may take long time for gaining adequate strength, where...

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...
