Roller Compacted Concrete

This article describes the Slovenian experience with PCC technology on four different sites with different requirements and for different purposes. The job mix formulas and the different application possibilities are described. Paver compacted concrete (PCC) is a relatively new construction method which was evaluated from roller compacted concrete (RCC) technology....

Colombia is a developing country with enormous difficulties for the implementation of new technologies due to their introduction costs and the positioning of existing ones. Despite the constant academic efforts to keep it alive, the construction of concrete pavements has been asleep for years as a consequence of the obsolescence...

This paper describes the investigation of the time dependent behaviour of roller compacted concrete pavements (RCCP) in port yards resulting from drying shrinkage and thermal stresses, and sedsuridi effects on the joint width. Test results show that even with a joint spacing of 8 m, approximately 1 N/mm2 of thermal...

In many countries rullw cumpactod concrete (RCC) proved to be a success as a construction method for highly stressed industrial floors, for concrete pavements, subbases for concrete pavements and asphalt surfaces. Since 1993 the Research, Development and Consulting Department of tho Heidelberger Zement AG is attended with a research project...

A new mix design methodology for roller compacted concrete (RCC) is described that involves preparing low and high density specimens at various (typically three) cement contents. For each specimen density is determined. Strengths (compressive and/or split tensile) are measured at various intervals (e.g., 1, 4, 7 and 28 days). Multiple...

Roller compacted concrete (RCC) pavements are expected to be an economic and rational concrete pvPmAnt system that will become increasingly popular in Japan. The maximum thickness of a RCC slab completed in one layer is limited to 25 cm because of limitations in the compactability of the concrete and the...

Roller compacted concrete pavements (RCCP) are favourable for port yards. To develop the design, both the bearing capai-ity and the load transfer efficiency at the joints were studied. An experimental pavement with two different RCCP structures was built: namely, one that follows the ordinary design method for port yards consisting...

Roller compacted concrete (RCC) began to be used in Spain in 1984 on roads bearing heavy and medium traffic. Up to now more than 250 km of RCC pavements have been constructed. A significant portion is subjected to the combined effect of heavy traffic and servere temperature gradients. Joints are...

Session Paper Indexes, Opening Addresses, General Reports, Oral Contributions and Closings from the 6th International Symposium on Concrete Roads 1990 Madrid Spain

The first known applications of RCC pavements in low-volume roads in Spain took place around 1969-1970. They included pavements located on housing developments, urban streets and rural roads. These applications have been increasing until now, when the technique is used in different parts of Spain and in other countries (Norway,...

Roller-compacted concrete (ReC) offers a solution to the vast number of good quality lowvolume roads which will have to be provided in the near future to accommodate South Africa's rapidly expanding rural road needs. The research effort presented in this paper involved a laboratory study and the construction and accelerated...

The first Ree full scale testing project in Norway took place in 1981. Since then appr. 260.000 m2 Ree have been placed. The use of Ree in roads in Norway has been directed by the following main principles: 1. Ree shall be a pavement with good bearing capacity, good resistance...
