Description:

Cement treatment of roadway or stockpile materials enhances the strength and stiffness properties of pavement base layers to meet structural requirements in a cost-effective and sustainable manner. Historically, cement stabilization mixture design criteria relied on compressive strength test results; depending on the treatment and test method, tests could take nearly a month to complete. In this project, researchers developed an accelerated design procedure for cement-treated base materials with a focus on rapid test turnaround times, lab curing techniques that quickly simulate cured field conditions, inclusion of moisture susceptibility in the mix design, and performance-related design criteria. The accelerated procedure uses 4-inch diameter, 2-inch tall specimens to measure the indirect tensile strength after an accelerated cure. This accelerated procedure produces strength results 4 days after molding specimens. The results from this accelerated procedure can also estimate the resilient modulus and modulus of rupture for use in pavement analysis and design checks.
