The use of demolished concrete as recycled aggregate in new concrete is a promising solution within the context of sustainable development. However, this application is still limited in the construction sector due to the lack of knowledge. In that context, Ifsttar (France) and the French industry's major players have finished...
Optimization of the Recycling of Concrete in Concrete Application to an Airport Slab
Environmental Performances of Roller Compacted Concrete Pavement
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...
Recyclable High Volume Fly Ash Pavement Concrete Using Limestone Aggregate
Fly-ash is a pozzolanic material, so it can contribute to various properties, such as strength development at mature age. The strength development at early age, however, is significantly slow and may negatively affect traffic service. Early strength may be improved when limestone filler is mixed in fly-ash concrete. In addition,...
Texture and Noise Characteristics of Exposed Aggregate Concrete Road Surfaces
Exposed aggregate cement concrete (EACC) road pavements are used on a large portion of the Austrian federal motorway network due to their durability and reduced noise emission. The standardized types with 8 and 11 mm chipping sizes have been characterized due to their noise emission and are subject to approval...
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...
Investigation on the Possibility of using Concrete Containing Plastic Waste as Aggregates for Pavement Construction
Increasingly plastics become the material of choice by product designers because they provide useful properties and for this reason the worldwide production of plastics is growing year after year. At the European level the reference concerning the recycling and reuse of waste plastics obliges Member States to recover and recycle...
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...
Long-Term Performance of Low-Noise Concrete Pavements
Traffic noise is one of the major environmental concerns within the countries of the European Union. 80 to 90% of the traffic noise pollution is generated by road traffic. The major part of the noise emitted by vehicles on roads in the mid- to high-speed range is nowadays due to...
