ECOPAVE is a system of laying concrete through a modified bituminous paver, inducing transverse cracks into the concrete, and overlaying with a thin bituminous surfacing. The system has been developed through a BRITE project with partners in the UK and Denmark. It is coiisideied to provide economic benefits over the...
Performance of the Ecopave System After Five Years Trafficking
Roughness and Ride Quality of Airport Pavements
This paper describes a method for routinely evaluating airfield pavement surface roughness from an aircraft ride quality perspective. The method is designed to be as compatible as practical with existing pavement management system data collection and reporting processes. Ride quality has always been recognized as a major factor in a...
Concrete Wheel Tracks – The Ecological and Economic Alternative in Rural Road Construction
The changes in the landscape happened during the last 40 years due to human activity have produced a slow change of mind. Therefore it is no wonder that also for road construction nature is taken more into account. The Concrete wheel track is a compromise. Firstly it prevents from covering...
Effects of Classified Fly Ash on Improving the Compactability of Roller Compacted Concrete for Pavements
Roller compacted concrete (RCC) pavements are expected to be an economic and rational concrete pvPmAnt system that will become increasingly popular in Japan. The maximum thickness of a RCC slab completed in one layer is limited to 25 cm because of limitations in the compactability of the concrete and the...
Reuse of Alkali Damaged Road Concrete in Cement Bound Road Bases
Aggregates were obtained from an alkali-silica damaged concrete road slab aggregates and used for road base concrete with different kinds of cement (low alkali cement, high alkali cement). After analysing the samples produced with these mixes, which were exposed for up to one year to different hardening conditions, no alkali-silika...
Wear Resistant and Noise Reducing Concrete for Road Pavements
Rutting, depending on the wear of studded tyres, is a problem in the Skandinavian couritiis. Concrete pavements have a good wear resistance. In Ai.ustria they have recently developed a low noise concrete with small aggregate size and exposed aggregate. Earlier experiences have shown that the wear resistance of concrete is...
Noise Reducing Techniques on Existing Continuously Reinforced Concrete Pavements on Belgian Motorways
Most of the Belgian Motorways, with a concrete pavement, have a deeply grooved concrete surface. Although those wearing courses have a very good skid resistance, there is a great concern about the noise pollution. Not only noise barriers and the porous asphalt overlay, but recently also the grinding are an...
Low Noise Concrete Pavements in Germany
Noise protection has been a main concern in Germany for a long time. The contribution of the road surface to the reduction of traffic noise is recorded with correction values and taken into consideration in noise protection calculations which are legally significant in the planning and construction of roads. These...
Noise Reduction on Concrete Paving Blocks
Today the people in the cities require, more than in former times, a nice looking but also noice reduced pavement. The aim of our one year trial in 1 9w92h,i ch was promoted by the Austrian innovation fund, was to fulfill the requirements mentioned above. 1200 m of new concrete...
Concrete Made of Building Demolition Waste
In the field of research on secondary materials, an experimental study on the re-use of building demolition waste has been conducted. These materials will be used in Italy, further to decree-laws and regulations, drawn in compliance with the rules of the Community Law 1 9 w93h, ich has already been...
Experiences with Noise Reducing Surfaces for Existing Concrete Pavements
In Carinthia a surface dressing with epoxy resin as binder and chippings 3/4 mm has been used since 1989. The task was to get better noise reducing conditions of existing concrete pavements. The result can be seen in noise reducing properties of - 6 db(A) compared with the existing old...
The Reuse of Old Pitch Containing Asphalt in Cement Bound Base Courses Depending on the Level of Harmful Substances
Large quantities of old asphalt containing varying admixtures of tar/pitch are produced during the renewal of asphalt roads. These pitches contain environmentally relevant substances such as pnlyr.yr.lic aromatic hydrocarbons (PAHs) and phenols which must not be allowed to leach out into the ground water. The intention is to bind the...
