TTI researchers developed a rapid mix design method for cement-treated base (CTB that reduces the test turnaround time for strength results from 7 to 4 days, as well as reduces the material quantity required for the strength testing. Given this project’s scope and data, the accelerated mix design procedure for CTB is suitable for road-mixed or stockpiled base materials. Researchers recommend that the mechanistic check from this project be added to the Texas Flexible Pavement System. The full research report provides a framework for how this mechanistic check could be efficiently implemented.
