In Austria, concrete pavement construction has a tradition of several decades and the technology used is regarded as mature. Nonetheless, improvements are required on a continuous basis. The sharp increase in heavy traffic, higher emission levels, including in particular noise emissions, as well as economic considerations taking into account the...
Flightdeck Crews and Runway Contrac-Tor Crews Working Together Face to Face on the 5th Extension to Zurich Airport Switzerland
During the extension to Zurich Airport in northern Switzerland, the Oberbau Civil Engineering Construction Consortium (Arbeits-Gemeinschaft) has probably been successful in completing the largest volume of concrete laying works in Central Europe by comparison with similar conversion undertakings. The works included the preparation and laying down of concrete runways, taxiways...
Road Marking on Concrete Roads
On several of the concrete roads that were constructed in Sweden during the 1990s problems have been experienced in making the road marking compound adhere to the road surface. The problem would appear to be greatest during the first few years. In earlier studies, the problem was analysed by laboratory...
The Acoustical Properties of Optimised Exposed Aggregate Concrete in the Netherlands
About nine years ago, the Dutch Association of the Netherlands Cement industry (VNC) initiated indicative noise measurements on three new types of concrete roads. It was shown that exposed aggregate had a potential for further optimising. The Dutch Information and Technology Centre for Transport and Infrastructure (CROW) initiated in 1996...
Skid Resistant, Noise-Reducing Concrete Roads
Concrete motorways providing high performance and durable operation have been manufactured for many decades; nevertheless, continuous advancements are necessary to fulfill changing boundary conditions. Major challenges here are posed by increases in the volume of traffic as special requirements of traffic safety, environmental compatibility and economy. In order to develop...
Management of the Aggregate Industry in Chile
In 1998, the Chilean private companies exploiting rock deposits for the aggregate production necessary in the construction industry, promoted the creation of the multilateral Commission with the purpose of solving problems of supply and demand unbalance, uncontrolled environmental impacts and serious legal gaps and/or superpositions. This Commission has been in...
Accelelated Loading Test of Porous Cement Concrete Pavement to Evaluate Durability and Permeability
This paper presents results of study on evaluating durability and permeability of porous cement concrete pavement by accelerated loading test at PWRI pavement test track. The following procedure was conducted to evaluate the durability and permeability of porous cement concrete pavement. Three test sections were constructed in 1997. These sections...
How Does the Micro and Macrotexture of Cement Concrete Pavement Affect the Skid Resistance of Road
The fast development of car technology has caused a steady increase in the speed of vehicles and increasingly higher demands on braking and traction. International studies show that every increase in average speed causes increase in personal injury accidents. Yet the present transport infrastructure in general and cement concrete pavement...
Surface Durability of Concrete Pavements
The surface (texture) of a concrete pavement has to endure the effects of traffic and the environmental load. At the Technical University of Munich, Institute for Materials and Structures the real stress from solvent, freezethaw and mechanical loads will be simulated in the laboratory as close as possible to practice...
Optimisation Model for Functional Properties of Concrete Roads
Concrete is a suitable material for road pavements, both technically and economically. That holds especially for roads with high traffic intensity and heavy loads. Concrete roads have several technical advantages such as high wear resistance and load bearing capacity, good durability and a bright surface. In order to make concrete...
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...
Life Cycle Assessment (LCA) of a Concrete Highway
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...
