DRYING SHRINKAGE OF ROLLER-COMPACTED CONCRETE FOR PAVEMENT APPLICATIONS
This paper reported the results of a laboratory investigation of the drying shrinkage of roller-compacted concrete (RCC) for pavement applications. The aggregate grading and moisture content of nine RCC mixtures were varied, and the drying shrinkage measured according to the procedures described in ASTM C 357, with some modifications. The 28-day drying shrinkage results of the mixtures ranged from 8 to 0.00033, with an overall average of 0.00015. The combined effects of moisture content and aggregate grading on the drying shrinkage were statistically significant, while the individual effects of moisture content or aggregate grading were not statistically significant. A regression model for predicting the 28-day drying shrinkage of RCC from the relative aggregate grading and moisture content was developed from the data, with a multiple correlation coefficient of 67%. The ACI Committee 209 model for predicting the drying shrinkage of concrete with time compared favorably with the RCC drying shrinkage data.
