Concrete pavers are often used for construction of urban area roads as they offer both easy and fast construction as well as high aesthetical value. Although noise reduction is also very important in urban areas, research focusing on low noise concrete pavers is still rare. This paper illustrates a study...
Failures of Concrete Slit Drains Caused by Negative Effect of their Erroneous Integration Into Surrounding Multi-Layer Road Systems
Concrete slit drains (also known as slot drains see fig. 1,2) are being used for the draining of highways and roads, as well as for large handling and parking areas. Recently, this system of drainage has become increasingly applied, which does, however, bring with it an increased incidence of...
A 32-Year-Old CRCP only with a New Porous Asphalt Top Layer still Fit for the Future
The A76 is the corridor between the Ruhr area (Germany) and Antwerp (Belgium) in the southern part of the Netherlands. It was built in 1985. Because the asphalt pavement failed as a result of a geological fault in the subsurface, a CRCP with a toplayer of porous asphalt was chosen....
A Dedicated Bus Platform in Castellón Spain
The metropolitan area of the city of Castellón, situated East of Spain at the Mediterranean coast, has a network of dedicated bus platforms, which was conceived with two main purposes: to enhance public transport and to structure urban development. As a part of this network, a bus platform, 3.9 km...
Influence of Test Specimen Compaction and Curing Condition for Pavement Cold Recycled Mixtures
Presently in most European countries the quality of cold recycling mixtures in pavement rehabilitation is proven by achieving required strength values (indirect tensile strength or compressive strength) and eventually by values of stiffness modulus (IT-CY test method). This empirical approach of quality assessment is quite simple, relatively fast in performance...
Roller Compacted Concrete Pavements for the Urban Environment Turkish Experience
Roller compacted concrete has traditionally been used for pavements carrying heavy loads in low speed areas because of its relatively coarse surface texture. However, its use in commercial areas for local streets and highways has been increasing, especially within the United States. Even though Turkey is one of the main...
The Advance of Concrete Pavement in Brazil
The Brazilian Army looked the Associação Brasileira de Cimento Portland (ABCP) for a strategic partnership, aiming to transfer technology and train the troops for such works. The result of this partnership was a full concrete pavement construction and control technology course, lasting two weeks, covering all stages, also including practical...
New Design of Exposed Aggregate Surface for Northern Entrance of Apeldoorn Constructional and Acoustical Aspects
Traffic noise, which is in fact the sum of tyre/road and engine noise, is one of the major disturbances for inhabitants. This has resulted in strict legislation with respect to maximum allowable noise levels at the facades of houses. Reducing traffic noise at the source by minimizing tyre/road noise can...
Innovative Photocatalytic Cementitious Road Materials
Photocatalytic cementitious road materials represent a new frontier in air quality improvement research, thanks to photocatalysts ability to accelerate natural reaction of oxidation, favouring the pollutants decay. This paper presents some findings that contribute to a better understanding of the effectiveness of photocatalytic road materials, evaluating the synergetic effect of...
Mexico City Interior Loop
Mexico City, one of the largest in the world, supports the traffic of more than 8 million cars. One of the main roads is the Interior Loop, with 42 km length in a 35 meter section. 110,000 cars transit daily on this loop. The maintenance of this road is under...
Contribution of Concrete Pavements to the Safety of Tunnels in Case of Fire
A number of tunnel fires in Europe have demonstrated the need for appropriate choice of materials for tunnel construction to ensure high safety and reliable availability to traffic. In case of fire, an incombustible and non-toxic road pavement, as it is a concrete one, contributes to the safety of people...
Recycling Center. New Concrete Overlay for the Existing Asphalt Pavement
The pavement of the so-called recycling centers in the cities requires special attention because of their special conditions. On the one hand, the pavement has to have adequate impermeability against different residues that could have potential contaminants that could leach into the subsoil. On the other hand, they should fulfill...
