From page 1...
... Project 9-29, as stated in the expanded scope of work, was to "evaluate and refine the IDT procedures proposed for use as the simple performance test for low-temperature cracking and as the materials characterization test for low-temperature cracking in the pavement design guide developed in NCHRP Project 1-37A." This report documents work completed in Phase III of NCHRP Project 9-29. The requirements of AASHTO T322, Standard Method of Test for Determining the Creep Compliance and Strength of Hot-Mix Asphalt (HMA)

From page 2...
... A laboratory test program was executed in this study to evaluate and compare measurement of creep compliance using the IDT, uniaxial compression, and uniaxial tension tests. An experiment comparing strength measurements was also performed to compare uncorrected IDT strengths, IDT strengths corrected using Roque's procedure as outlined in AASHTO T322, and strengths determined in uniaxial tension.
