A New Youth For An Old Lady – Rehabilitation of the Lorraine Avenue in Brussels – Belgium

Conf-paper-iscr

The ‘Drève de Lorraine’ in Brussels is an old forestry road connecting the highway to the south part of Brussels. It has been built in 1925, using concrete slabs of 15 cm thick lying directly on the natural ground. After 78 years of good services, this road has been rehabilitated...

Surface Durability of Concrete Pavements

Conf-paper-iscr

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...

How Does the Micro and Macrotexture of Cement Concrete Pavement Affect the Skid Resistance of Road

Conf-paper-iscr

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...

Combustion of Asphalt and Concrete in Case of Fire in Roads

Conf-paper-iscr

The present study concerns the comparison of the behaviour at high temperature of an asphalt and that of concrete, the purpose being to define the parameters of choice of the material for the construction of roads, in particular in tunnels. To do this, laboratory tests of fire, thermal behaviour and...

Modieslab Innovative Prefabricated Modular Concrete Slab For Concrete Roads and Airfields

Conf-paper-iscr

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...

Investigation of Maintenance Needs For In-Service Concrete Pavements

Conf-paper-iscr

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....

Development of Cement Treated Asphalt Mixtures for Pavement Rehabilitation

Conf-paper-iscr

Cement treated asphalt mixtures (CTAM), which are composed of an asphalt mixture and cement milk injected into voids of the asphalt mixture, were studied for use as a fast overlay material for airport pavements. The cement milk must have adequate fluidity for about 30 minutes and must develop a flexural...

Renovation of an Apron in Front of a Hangar on Brussels National Airport Using Quick-Setting Concrete

Conf-paper-iscr

The pavement of the apron on Brussels National Airport, which was constructed in the early sixties, was forming cracks. Given that fragments of concrete could in time be a danger to the aircraft engines, a thorough renovation of the apron was imperative. The distinctive feature of the site is that...

Rehabilitation of Concrete Slabs by Sifcon-Overlays

Conf-paper-iscr

A new means for rehabilitation of severely cracked concrete slabs is a thin overlay of SIFCON (Slurry Infiltrated Fibre Concrete). This high strength concrete with an extremely high content of conventional steel fibres (about 10 % of volume) was invented in the USA and further developed by the central laboratory...

Use of Crack and Seat in Concrete Pavement Rehabilitation a Case Study

Conf-paper-iscr

This paper describes the processes carried out in the crack and seat of an existing concrete pavement on the M40 Motorway in England.

Repair of Concrete Pavements Using High Performance Concrete

Conf-paper-iscr

When heavily trafficed concrete pavements are being renewed, the work generally has to be carried out under considerable time-pressure. A newly developed, high performance repair concrete is ideally suitable for such repair work on account of its high early and final strength as well as its durability. It is produced...

A Study on the Thin Precast Concrete Pavement for Rehabilitation of Asphalt Pavements

Conf-paper-iscr

Precast concrete pavcmrnts have the merit to supply concrete slabs of good quality. In the concstructiori of precast concrete pavements, it is not necessary to use any special machines. And the special merit is that traffics can open immediatly because of unnecessary of curing. So this type of concrete pavement...
