Concrete pavements have been used in Germany mainly for federal motorways, airfields and industrial areas and less for state and provincial roads. By-passes have been constructed with asphalt pavements. In 2001/ 2002 a by-pass in the course of a federal trunk road was constructed with a concrete pavement for the...

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,...

The property of abrasion resistance is the ability of a material to resist mechanical abrasion. This paper deals with different test methods, especially road wear simulators, requirements and influencing factors for wearresistant road surfacing concrete. The average annual daily traffic (ADT) adjusted for the proportion of traffic with studded tyres,...

Given the large number of concrete pavements that have performed well over time and lived up to prior expectations, as well as the knowledge that is now available regarding the reasons for failure in certain concrete constructions, it should be possible to carry out an evaluation of these pavement types....

The Dutch Federal Highway Administration introduced the project “Roads to the Future” in the year 2000. Amongst other innovations, the MODULAR ROAD, was one of the sub-projects. In a contest several parties in the roudbuilding business were asked to develop an idea for a modular type of road that had...

In the Netherlands Rijkswaterstaat is the authority in charge among others of the construction of highways. The department Noord Holland of Rijkswaterstaat has chosen a continuously reinforced concrete roadbase for the construction of the 9 km long new highway section between the cities of Haarlem and Hoofddorp. This choise was...

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...

The paper describes an application of ultra-thin white-topping on a bituminous factory pavement. Different road cement concrete mixes were studied: high-strength concrete, concrete with PP fibres added, concrete modified with latex, concrete made by tyre-rubber grains instead of natural aggregate and steel fibre reinforced concrete. The binder was CEM II/A-L...

For concrete pavements the new “thin upper layer concrete“ construction method, potentially in connection with the method of “thick concrete pavement“ placed on an unbound roadbase enables a 40mm thick upper layer concrete having a maximum aggregate size of only 8mm to be placed instead of a 70mm thick upper...

The pavement management of concrete roads in Ge rmany is essentially based on surface-referred status datas. Suitable measuring techniques are available for the data aquisition. Approved and practicable methods apply for their evaluation. However there are no appropriate procedures and concepts for the structural substance evaluation regarding the prognosis of...

Concrete pavements which are placed during hot summer weather conditions, harden on the top side, due to the solar radiation, at higher temperatures, as is the case for the bottom side. As soon as the concrete cools down at the top side during the first night, the concrete pavement tends...

The considerable increase of road traffic all over the world increases the demand for traffic surfaces with a longer lifespan and less repairs. When doing maintenance and repair works it is very important to keep short construction times in order to reduce obstruction to traffic to meet this challenge. A...
