Abstract:

Research Project 0-7027 developed an accelerated mix design procedure for cement-treated base materials, with attention to test turnaround time and inclusion of moisture conditioning. This project found that the indirect tensile (IDT) strength method with a 72-hour accelerated cure (where specimens are sealed at 104°F) followed by 24-hour moisture conditioning through water submersion (IDT3) provided the most suitable basis for mix design of the accelerated-cure methods investigated. The recommended IDT3 method used 4-inch-diameter, 2-inch-tall specimens, compacted in the Superpave gyrator compactor. This product presents results quantifying the within-lab precision of the IDT3 method. The results from this product can assist in evaluating the expected level of agreement between repeated tests of like materials when tested within a single laboratory.
