Concrete block pavements have a good load carrying capacity and load distribution ability. The concrete block pavement is durable, insensitive to settlements, easy to repair, bright, and aesthetically attractive. It has therefore frequently been used in urban environments. In Sweden, however, concrete block pavements have been less frequent than in...
A Design Method of Composite Pavement with Asphalt Surface Course and Continuously Reinforced Concrete Base Course
This paper describes a structural design method developed for composite pavement which is composed of an asphalt surface course (ASC) and a continuously reinforced concrete base course (CRCB). The design method is based on the fatigue analysis of CRCB. In the analysis, loading and thermal stresses in (2RU13 are calculated...
Rollcrete Bas – CBGB for the Tag Motorway in Turkey
Rollcrete Base - also called Cement-sound Granular Base (CBGB) - is basically a dry material bound by Portland cement, placed using an adapted asphalt paver, and vibrated externally. One of the first applications of rolicrete for the Trans European Motorway project was on the Tarsus - Adana - Gaziantep (TAG)...
Enlargement of the Belgian Motorway E40 Brussels-Liege in Kortenberg
The section Brussels-Louvain of the motorway E40 was constructed in 1971 with a pavement in continuous reinforced coticiete fui the tlnee tiaffic lanes and an asphalt pavellielli for the elulergency lane. tue to the increase of heavy traffic, the Flemish Government decided the construction in 1994 of a fourth traffic...
Study of Rigid Pavement with Puzzolanic Over Sulfated Binders
The paper presents the employed materials, including binder (Romanian patent) for the technology of mixing and laying of reinforcement concrete for an existing flexible pavement. After thirteen years of significant traffic (over 1.2 millions 100 kN axles) the pavement behavior is correct, proved by the state of slab margins and...
Influence of Fly Ash on Abrasion Resistance of Concrete for Roads Pavements
In Portugal, fly ash is often used as a cement replacement material on concrete for road pavements. The percentages of replacement generally range from about 30% in the top pavement layer up to 50% in the bottom layer. A study was carried out for evaluating to what extent such amounts...
Performance of the Ecopave System After Five Years Trafficking
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...
Concrete Pavements for Heavy Traffic Areas
The space available on our roads is becoming less and less. All forecasts agree that the increase in traffic will also cotiliiiue to grow considerably in the years before us. At the same time, because of the changes in political conditions in Europe and the opening of the frontiers, there...
Development of Cement Treated Asphalt Mixtures for Pavement Rehabilitation
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...
Reconstruction and Recycling of Concrete Pavements
After 30 to 35 years heavy traffic loading concrete motorways have to be reconstructed. In Germany, the old concrete pavement was ]ft in its place and overlaid with a new pavement. This reconstruction method may be really economical under definite circumstances but is hardly practicable for the contemporary reconstructions, especially...
Reconstruction of Concrete Roads Using Recycled Sand as Aggregate
In the domain of road building, recycled aggregate made from old concrete road pavings has been used in the construction of new concrete pavings for quite some time. Generally only the coarse fractions of more than 4 or 2 mm, respectively, are used as recycled material. Most of the recycled...
The Behavior of Concrete Block Pavements
In 1981 to 1985 and 1993/94 static and dynamic tests on block pavements were carried out on a 1:1 scale at the professorship of Road Construction at the Technical University of Dresden. The pavements were loaded with a plate bearing test equipment (approx. 0.7 N/mm 2) with a static stress...
