Abstract Roller compacted concrete (RCC) has gained acceptance as a paving material due to its strength, economy and fast placement. In this paper, variation in aggregate type and influence of GGBS on drying shrinkage properties of RCC was explored. The experimental results indicate that crushed gravel aggregates presents higher shrinkage strain as compared to limestone. Also, the shrinkage strain of RCC increased with the increase in replacement level of cement with GGBS. Further, a multivariable regression model is developed for shrinkage strain prediction of RCC, considering the effect of aggregate type and percentage incorporation of GGBS on the shrinkage behaviour. The obtained higher correlation coefficient indicates that the developed model can be effectively used to predict the shrinkage strain of RCC.
