Roller compacted concrete technology for vehicle parking area solutions

Abstract

The purpose of the article is presenting the application of the roller compacted concrete (RCC) as alternative solution to asphalt parking places and roads, showing the advantages and further possibilities for development of RCC in wide range of projects. RCC is produced similar to conventional concrete. However, RCC is zero slump concrete unlike conventional concrete. In this study the construction for parking area in RCC technology is presented for the real project. Presented cases concern heavy and light vehicles parking areas. The experimental results shows the very good quality of RCC placed on site, high compressive strength of the concrete, good workability of the concrete mixture that allows for proper placing of the concrete. RCC provides better mechanical-durable properties, more economical and less carbon footprint based on proper compaction and on lower water/cement ratio comparing to conventional concrete. The article draws attention to the role of the soil under the RCC as well, which should be designed and prepared on site with an appropriate stiffness and should be made according to the requirements resulting from the use of RCC. Such a comprehensive implementation of the soil-RCC subbase system guarantees the proper quality, load-bearing capacity and durability of the structure of the parking places as well as roads, for the assumed period of operation.
