Abstract

The paper reports two methods presently under consideration by ASTM: a standard practice for casting RCC cylinder molds using a vibrating table and a standard practice for consistency and density of RCC using a vibrating table. Within the limitations of the experimental project, conclusions are drawn: that the vibration/surcharge method gives lower density and higher compressive strength than impact methods; The more appropriate laboratory consolidation method for RCC pavements cannot be decided without correlation to field data, but that the laboratory fabrication method yielding the highest density would result in the most stringent specification.In terms of specimen size and shape, the use of a 10.2 cm by 20.3 cm cylinder should be preferred for ease of workmanship and correlation to field drilled cores. Since it is very cumbersome to produce RCC beam specimens with any laboratory consolidation method, only compression and/or splitting tension tests should be required.
