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...
Possibility of Using Concrete Roads in Turkey
Axle loads are increasing all over the world including Turkey. Asphalt pavements are not able to carry this heavy traffic safely and economically. Using asphalt pavement for heavy traffic cause early deterioration of the pavement and higher cost of pavement maintenance. As an alternative, concrete pavements may be used instead...
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...
Cement Containing Granulated Blast Furnace Slag in Local Roads Building
The number of roads with concrete surface in Poland is small. During the last few years the cement industry has taken up extensive promoting activities that resulted in increased interest in construction of concrete roads both motorways as well as local roads. It has turned out that durability of...
Effects of Slags Produced in Turkey on Chloride Penetration of Concrete
In this study, effects of slags widely used as mineral admixture in concrete industry on chloride penetration of concrete were investigated. Three different slags were used as replacement of cement (PC42.5) by weight of 25%, 50%, 75%. Setting test , determination of specific gravity, determination of specific surface were carried...
Full Scale Pavement Tests of Exposed Concrete Aggregates: Acoustical Aspects and Friction Characteristics
Traffic-noise pollution has become an issue for many road authorities. Applying measures at the source i.e. interaction surface and wheel are an effective noise abatement measure and many quiet surfaces have been developed in the last decade. A relative silent surfacing is a concrete surface of exposed aggregates. The Dutch...
Concrete Roundabouts
As is the case in several European countries, Belgium is also constructing more and more roundabouts at busy intersections. They offer a better guarantee of a fluent, but at the same time safer, flow of traffic. The road surface of a roundabout is placed under a heavy load. In addition...
Dowels in Jointed Plain Concrete Pavements
The general type of concrete structures on German highways is the Jointed Plain Concrete Pavement (JPCP). Contraction joints are saw-cut with a standard spacing of 5,0 m perpendicular to road axis and sealed by a bitumen based or elastomeric joint filler. International experiences indicated clearly that faulting at undowelled transverse...
Repair of Concrete Pavements Under Op-Eration
Don't we all loath them traffic jams. Irrespective of how we are affected by them, either directly as a user of traffic infrastructure or as a construction worker involved with its upkeep or indirectly as a conscious citizen aware of their economical impact, we all wish they could be...
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...
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...
Reasons for Cracking of the Cement Concrete Pavements from Strong and Frost-Resistant Concrete
World practice (USA, Germany) has already noted the cases of continuous cracking of the surface layers of cement concrete pavements. Continuous cracking becomes evident several years later after completing construction and results, as a rule, in deterioration of the performance characteristics of the pavements. The paper shows the results of...
