Microcracking for Reduced Shrinkage in Cement-Treated Base

This project focused on evaluating the effectiveness of the microcracking concept for reducing shrinkage cracking in cement-treated bases. Microcracking can be defined as the application of several vibratory roller passes to the cement-treated base at a short curing stage, typically after 1 to 3 days, to create a fine network of cracks. The goal of microcracking is to prevent severe, wide cracks from forming and thus reduce the risk of problematic reflective cracking through the pavement surfacing.
