9、.1 This Test Method is used to prepare specimens contain-ing a nominal maximum aggregate size of up to 37.5 mm 1-12in.and a Vebe consistency time,in accordance with TestMethod C1170/C1170M,of greater than 30 s for determiningthe density of compacted RCC mixtures.This method is notintended to specify
10、 a standard compactive effort in RCCmixture design,but rather to provide a standardized method forcomparing various aggregate combinations.4.2 This test method may be used for making specimens anddetermining densities of laboratory-produced RCC mixtures.NOTE1The agency and personnel performing this
11、test method shouldmeet the criteria of Practice C1077 or equivalent.NOTE2The use of gyratory-compacted RCC specimens for strengthdeterminations is not recommended due to specimen geometry and lowL/D ratios.Research has shown a lack of correlation between compressivestrengths of gyratory-compacted RC
