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...
Exposed Aggregate Concrete Pavement Design Construction and Functional Performance-A Comparison of European and US Experiences
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...
The Construction of the Rosario – Cordoba Highway An Emblematic Project of the Road Activity in Argentina
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...
Slab Jacking Development of New Materials
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...
Roundabouts with Concrete Pavements: Austrian Experiences
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...
Specifications for the Construction of Steel Fibre-Reinforced Roller Compacted Concrete Roads
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 /...
Replacing the Aggregate by Rice Husk Ash in Roller Compacted Concrete for Composite Pavements
World rice production reaches 662 million tons per year. The husks represent 20% of this amount and when burned, 20% of this byproduct is transformed into rice husk ash (RHA). In general, there is not an environmental management policy concerning this residue. Roller compacted concrete (RCC) is a material which...
Concrete Pavement in the Streets of Access to Paranaguá Port in the South of Brazil Portside Area Revitalization
The objective of the concrete pavement construction design of the main access streets to all Paranagua Port Terminals was to improve the traffic of trucks which transport goods being imported into and exported out of Brazil. Concrete pavement was the final engineering design chosen for this job due to the...
Roller Compacted Heavy Concrete (RCHC) for Pavement Strength and Density
In the technology of the Roller Compacted Concrete (RCC) for pavement, various types of aggregations are used classically as aggregates, such as the crushed and the rolled aggregates limestone and siliceous, giving concretes with a relative density in the order of 2200 to 2300 kg/m3. In the present work, we...
A New Design Method of Concrete Pavements
In this paper a new design method of plain concrete pavements without bond to the subgrade is presented. For the first time, stresses resulting from environmental conditions will be considered in a realistic way in addition to stresses due to live loads. The basis of this new design method is...
CRCP a Cost-Effective Long-Life Pavement Solution for Highways & Expressways
Continuously Reinforced Concrete Pavement, CRCP is a concrete pavement that is reinforced with steel bars in the direction of traffic. CRCP is a durable pavement solution, advancement to plain concrete pavement. Reinforcement is used in CRCP, to tackle the problem of concrete slab cracking, instead of joints used in conventional...
Using Evenness Data for the Systematic Application of the Falling Weight Deflectometer on Concrete Roads
In many countries the Falling Weight Deflectometer (FWD) is used to assess bearing capacity and thereby the structural condition of concrete roads. Due to the fact that the FWD is a stationary measuring system it can be used only for object related assessment of bearing capacity, but not for network-level...
