Roller Compacted Concrete

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...

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

In this paper the results of several experimental studies carried out in order to determine some properties of RCC are described. These properties are important to design and to control RCC pavements: - comparison between strain modulus of different RCC and vibrated concrete mixes whose mechanical strength were similar; proposal...

The use of roller compacted concrete in high-way works started in Argentina in 1986 through a programme developed by the Instituto del Cemento Portland Argentino, ICPA (Argentine Portland Cement Institute). Several sections were designed and constructed in different areas of the country, using traditional laboratory tests, mix proportioning methods and...

Measurements of the energy of ultrasonic pulses as a means of establishing the relationship between the structure of material md its properties, have bcen studied during a long period of .ime in the Torroja Institute. Energy quantification of the pulse does consider all the characteristics of wave and materials. This...

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...

Roller Compacted Concrete Pavements have been constructed on six US Forces military installations within the Federal Republic of Germany (FRG). These RCC pavements will be used as hardstands supporting either wheeled or tracked vehicles. RCC hardstands within the FRG have saved as much as 22 % of the construction cost...
