Skid resistance properties of concrete pavement surfaces in tunnels are measured with the dynamic measuring device TRT on a regular basis in the Czech Republic. Measurements are usually carried out before and after putting the tunnel into operation and then approximately once a year; the skid resistance is also measured...
Skid Resistance Properties of Concrete Pavement Surfaces in Tunnels
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...
Super Fast Concrete Repair System for Roads Airfields and Railways Based on a Special Cement for Infrastructure Projects
From both an environmental and economic point of view, the availability and performance capability of infrastructure traffic areas today and in the future is of the highest priority. This applies to both public and private roads and air traffic areas, as well as for busy parking and logistics areas and...
Concrete Pavement Preservation Integrating Engineering Application and the Environment
Concrete Pavement Preservation (CPP) is a series of engineered techniques developed over the past 40 years to manage the rate of pavement deterioration in concrete streets, highways and airports. CPP is a non-overlay option used to repair areas of distress in concrete pavement without changing its grade. This rational, preventive...
Environmental Product Declaration of Czech Cement
This paper explains the basic concepts, history of studies and the results of the Life Cycle Assessment (LCA) of the Czech Cement and Environmental Product Declaration (EPD) of the Czech Cement. The Environmental Product Declaration is based on the method of life cycle assessment, which generally evaluates the impact on...
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...
Pavement Type Hysteresis and Truck Rolling Resistance
Portland Cement Concrete (PCC) pavements usually incur higher investment costs than Asphalt Concrete (AC) alternatives. In a life cycle analysis the higher cost is justified by lower maintenance costs, less and fewer traffic flow intrusions, and a longer technical life. All these factors contribute to a reduction of the carbon...
Noise Emission Comparison Between Porous Concrete and Porous Asphalt Road Pavements
In this investigation the Authors developed a particular grading curve for the manufacture of a porous concrete road pavement and assessed the noise emission due to vehicles tyres rolling belonging to its use. In fact, this innovative superstructure, apart from guaranteeing excellent superficial characteristics from the standpoint of grip and...
The Road Traffic Noise Attributes of Some Portland Cement Concrete Pavement Surfaces in Australia
This paper presents the conduct and outcomes of a series of investigations aimed primarily at determining the noise attributes of several rigid and flexible pavement surfaces currently in service in Australia. The investigations, which included both Portland Cement Concretes and Asphaltic Concretes, have been conducted over the last five years...
Genesis of a Comprehensive Concrete Pavement Noise, Texture, and Friction Data Collection Program
The lack of quality data that relates tire-pavement noise to the texture of concrete pavements has hindered the pavement community in both understanding the phenomena and finding ways to minimize its impact. The National Concrete Pavement Technology Center (USA), the US Department of Transportation Federal Highway Administration, and the American...
Increased Application of Sustainable Concrete Pavements in the Netherlands
Since the late 80ies in the Netherlands more and more cross-sections are constructed as roundabouts in stead of a cross section with traffic-lights. The pavements and prefabricated elements suffer from heavy traffic-loads and lots of maintenance was required. Therefore the last years it is investigated how sustainable roundabouts could reduce...
The Skid Resistance in Mexican Concrete Roads
This work describes the activities developed in Mexico to improve the selection criteria for stone aggregates which are used in surface layers for concrete pavements. The experience has shown that the current mechanical resistance requirements for stone aggregates often do not assure an adequate behavior. In other words, the selection...
