Construction

The Strategic Highway Research Program 2 (SHRP 2) recently completed a study entitled, “Real-Time Smoothness Measurements on Portland Cement Concrete Pavements during Construction”. As part of this project, the feasibility of this technology was explored. There was both an evaluation and demonstration of emerging and proven technologies. Model specifications and...

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...

The technique of continuously reinforced concrete for pavement construction is being applied in Belgium since the 1960s. The original design underwent several changes over time, sometimes for economic reasons but mostly in order to improve the long term behaviour of the pavements. Today there are still possibilities for further optimisation,...

In the last few years at several airports cracking in the internals of concrete gutters has been detected. This was mainly observed, where large airfields (about 60 to 100 m in length) are located next to these drainage lines. In order to reveal the influences on this cracking both laboratory...

The technique of continuously reinforced concrete is used in Belgium for the construction or rehabilitation of heavily trafficked motorway sections. Since a few years, double layered CRCP is being considered in order to improve the rolling noise characteristics of the surface. In this paper, two worksites where CRCP was used,...

A number of concrete surfaced roads in the UK have been in service for over 30 years. In some cases, the original surface laitance applied to these carriageways is becoming worn, leading to reductions in texture and skid resistance, a combination that has been shown to have a negative effect...

In Zurich the underpass Bleicherweg had to be maintained. An important part of the job was the pavement. The civil engineering department of the city of Zurich decided that the original asphalt pavement had to be replaced with a concrete pavement. The base of this decision, minimize possible water vapor...

Among various construction activities, related to concrete pavement technologies, an important role is reserved to industrial floors; these structures, in many cases, present the same technical problems of road pavements. Characteristics, construction techniques, exercise conditions, maintenance and control of industrial pavements, in effect, are very similar to the ones usually...

The constantly rising traffic volume is leading to high mechanical stress of the pavements. As a result, the requirements of maintenance, refurbishment and renewal are increasing. In contrast to this, financial resources are decreasing constantly. Moreover, the increasing traffic noise emissions are experienced as growing stress. New, highly sustainable and...

Highways superficial rehabilitation appears nowadays as one environmental friendly option to increase the service life of pavements. The remaining structural section is responsible for providing enough resistance for the ongoing traffic loads. The basic goal of this kind of treatments is to recover a certain level of comfort and security...

In Germany, diamond grinding is frequently used to improve the evenness and skid resistance of concrete pavement surfaces. Since diamond grinding has been observed to affect tyre / pavement noise emission favourably, the relationship between surface texture, concrete composition and noise emission of concrete pavement surfaces has been systematically investigated....

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...
