The use of RCC is now well established for industrial pavements, and is spreading in North America and recently in Europe for transportation pavement with high mechanical performances requirements such as Tram or Bus platforms. Cost advantage and mechanical performances are two undeniable benefits of this technology. The development of...
Skid Resistance of Concrete Pavements and their Durability
The article states that a relative traffic accident risk depends on the values of skid resistance and its durability, which are both influenced by the texturing of Concrete pavements (CP). From the very beginning of the CP construction in the Czech Republic, transverse tining was used for surface texturing. The...
Re-use of Marginal Aggregates in Cement Bound Mixtures for Pavement Foundations
The paper reports the results of an experimental study aimed at designing cement bound granular mixtures for pavement foundations, made exclusively with marginal materials, namely electric arc furnace steel slags, ladle furnace slags, waste foundry sands, glass wastes and coal ashes, used with different proportions. The laboratory investigation has been...
Multi-Funcional Noise Reducing Pavements Made of UHPC – Materials Design and Construction Technology
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...
Operation Experiences on Concrete Pavements During the Last 10 Years in Hungary
Since the middle of 90s in Hungary the permanent deformations of semi-rigid asphalt pavements have become a major problem due to increasing traffic and changing climate conditions. It has been a particular challenge concerning the M0 motorway around Budapest exposed to the most serious heavy vehicle traffic. The preceding test...
Recent Advances and Uses of Roller Compacted Concrete Pavements in the United States
Roller Compacted Concrete (RCC) is a no slump concrete that is placed by an asphalt paver and compacted with vibratory rollers similar to asphalt pavement construction. RCC has long history of good performance as a pavement for ports, container yards, and manufacturing plants. This paper will summarize a recent survey...
Working Mechanisms of Air-Entraining Admixtures and their Subsequent Activation Potential
From some job sites it was reported that the air void content of the hardened road concrete was considerably higher than that of the fresh concrete, especially, when air-entraining agents based on synthetic active constituents have been used. Investigations in the Research Institute with commercial air-entrainers based on synthetic and...
Design & Construction of An Experimental Two Layer Concrete Pavement Motorway Section in Spain
In June 2006, GISA a Public Company GISA, 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...
Sustainability and Concrete Pavements for Real Engineers
Practicing engineers are under increasing pressure from pavement owners to become ?sustainable?. There are a myriad of publications, models and rating systems available that aim to assist them in this endeavor, in fact so many that they become overwhelmed. This paper provides practical guidance that includes definitions of the terminology,...
Measurements of the Emissions of Particulate Matter (Pm10) from a Concrete Compared to a Stone Mastic Asphalt Highway
A mobile measurement system was used to quantify the relative importance for the road dust particle emissions on highways with concrete and stone mastic asphalt (SMA). Studded and non-studded winter tires were tested at 70, 90 and 110 km/h. The measurements were performed during October on dry, clean roads. Both...
Modern SFHC Super Fast Hardening Concrete Repair System for Airfields and Roads, Based on Special Cement for Infrastructure Projects
The importance of fast traffic area repairs is increasing. For roads and airfield service areas a specific fast repair system has been developed to satisfy the demand. This system uses standard methods of ready-mixed concrete and is appropriate if a few additional requirements are taken into account. The placing is...
Concrete Bus Lanes
Cities worldwide are facing problems of traffic congestion in their centres and suburban areas as well as on access roads. In densely populated countries like Belgium and the Netherlands this phenomenon also occurs on roads linking cities. Because of these mobility problems and the serious impact on the environment, decision...
