The environmental performance of a Swedish concrete highway was analysed by use of Life Cycle Assessment (LCA). As a base, a similar study carried out in Finland was used [1, 2]. The system investigated include extraction of raw materials up to the user phase (traffic and lighting). The intention of...
Life Cycle Assessment (LCA) of a Concrete Highway
A Fast and Comfortable Public Transport Lane in Continously Reinforced Concrete
The Zuidtangent is a free high quality public transport lane between the city of Haarlem and Schiphol Airpoprt. The full trajectoryi s built in continouusly reinforced concrete. In this paper some design aspects are described. Also the use of concrete as a wearing course on bridges and in tunnels is...
Surface Platforms For Public Transport New Perspectives: the Case of Cement Concrete
As a result of Urban Travel Plans implemented in major cities, public transport is being favoured as a convenient means of travel and mobility by all. Platforms (road- and trackbeds) designed for public transport must offer quality from the technical standpoint in order to handle channelled loads or the insertion...
Backcalculation Analysis of Concrete Pavements Using Fuzzy Logic Approach
It is known that concrete and flexible pavements are similar each other from the structural view point. Nowadays, especially, because of the innovations in airplane technology, airplane weights have been increased. Therefore airport maintenance has become more important. It is possible to obtain information about structural performance of a pavement...
Benefit of Reduced Fuel Consumption from Economic and Environmental Perspectives a Novel Approach
Road traffic now represents one of the major sources of environmentally and hygienically harmful emissions. A reduction of the total quantity of traffic-related emissions would therefore yield great environmental benefits. A number of independent studies have demonstrated that the properties of the road, such as surface texture and rigidity, affect...
Road Concrete with Screenings of Igneous Rocks
The use of screenings of igneous rocks containing the dust-like particles (not more than 10% by weight) extends the list of efficient aggregates for the pavement concretes. The peculiarities of the grain size distribution of screenings, namely, an increased content (up to 10% and over) of dust-like particles and specific...
Geotechnical Properties of Cement Stabilized Class-F Fly Ash
The geotechnical properties of cement added class-F fly ash have been investigated to assess the potential utilization of stabilized fly ash as embankment material. The engineering properties of the cement stabilized class-F fly ash studied include the compaction, strength characteristics and the durability as measured by wetting and drying tests....
Concrete Roads and Road Lighting Design
Knowledge about pavement reflection properties is needed in order to design a road lighting installation. CIE (International Commission on Illumination) has created a method for describing the reflection properties of a dry surface in terms of the pavement brightness and degree of specularity. From here, CIE has created a classification...
Continuously Reinforced Concrete Pavement in a Tunnel in Liege Belgium
In June 2000, a new motorway link (E25-E40) was inaugurated in Liège to solve transit and local traffic problems. It serves more than 65,000 vehicles a day in both directions. With multiple technical, environmental and security-related constraints, the 5 kilometres of this infrastructure prefigure numerous works such as bridges, roads,...
A Low Cost Equipment For Accelerated Testing of Pavement Materials
Testing the behaviour of different pavement materials under repeated application of loads has been recognized as very essential to predict the performance of pavements. Most of the methodologies /equipments used to carry out such tests involve huge sums of money both in terms of initial investment and recurring expenditure. Also,...
Feasibility of Continuously Reinforced Concrete Construction in Turkey
Continuously reinforced concrete pavements (CRCPs), when proper design and construction guidelines are followed, may allow more than thirty million equivalent single axle load application as observed at existing CRCP sections in the United States of America. Otherwise, the CRCP may prematurely fail and require costly maintenance earlier than anticipated. In...
Effect of Concrete Road Roughness on Dynamic Response of Girder Bridges
The dynamic response of highway bridges subjected to moving truckloads is observed to be dependent on dynamic characteristics of the bridge, vehicle dynamics, and road surface roughness profile. Road roughness and the bump at bridge entrance between bridge and concrete approach slabs are the major contributors to the dynamic amplification...
