In this research the influence of sand grading on the air void system in mortar is determined. Three sand grading types are defined: sand “low”, sand “mean” and sand “high”. The difference is the amount of fines, < 250 ?m, (low, mean and high amount of fines) in the sand....

New legislation for improving accessibility to buses by people and especially disabled people led to the modification of bus platforms and particularly the kerbs at these platforms. Buses should be able to approach quite close to these platforms. This depends on the design of the bus stop area. The dimensions...

On site pavement recycling with cement is the most sustainable restoration technique, by means of which a degraded pavement is transformed into a consistent and more homogeneous structure, using the road as a source of aggregates. Both bearing capacity and homogeneity are therefore considerably improved. Due to the absence of...

While much research in the United States (U.S.) has focused on the development, enhancement, and sensitivity of the AASHTOWare Pavement ME Design (previously known and MEPDG and DARWin-ME) method, little work has focused on comparing the results from this design method to other design methods already regularly used in practice....

The Mexican Federal Government has allocated a great deal of investment to the maintenance of pavements across the existing road network (in 2010 and 2011, this investment amounted to €7,860M and €7,894M respectively). During the 1990s, a pavement system was introduced in Mexico involving the incorporation of Portland cement using...

Porous surfaces of cement concrete (OPB) or asphalt concrete (OPA) have a permanent transfer of rainwater and additionally noise reduction potential compared to the dense microstructure with exposed aggregates concrete. Pervious concrete test sections in the field of heavy-duty highways previously reported, however, do not have sufficient durability. Causes of...

Long-life concrete pavements require less frequent repair, rehabilitation, and reconstruction, and therefore contribute to improving highway safety and mitigating congestion. Experience with these pavements, including examples of concrete pavements that have remained in service for more than 35 years. CRCP set out to offer the market a new alternative in...

In 2006, a group of highway agency and paving industry representatives from the USA visited Europe in search of current practices for the design, construction, maintenance, and rehabilitation of concrete pavements. In every country visited, examples of exposed aggregate concrete were demonstrated. While not a new discovery, the discussions did...

Due to the magnitude of the project, its characteristics, and the economic and cultural development of the region where it settles, the construction of the Rosario – Cordoba Highway represents an emblematic project of the road activity in Argentina. A singularity of this motorway is that it has been built...

In order to extend the lifetime of concrete roads for many years, it is very important to secure a proper maintenance. Loosely embedded slabs, for example, should be stabilized and, if necessary, jacked in an early stadium in order to prevent further damage of these and the bordering slabs. The...

The concrete construction method is predominantly used in Austria for the high-rank road network (motorways, expressways) with heavy traffic and / or a high percentage of heavy vehicles. Re-cently, concrete pavements are also used in case of low traffic loads (track lanes, concrete paving blocks) and for roundabouts. This contribution...

Depending on the prevailing material and energy prices, concrete roads can be made more cost-effective than asphalt roads. However, to provide a truly sustainable solution, it is necessary to reduce the energy consumption associated with the production and maintenance of concrete roads, as well as to minimise their construction /...
