IDEAL-CT Reporting Form | The Maryland Asphalt Association, Inc.

Recently, there has been a need for a practical cracking test for routine use in the process of mix design, quality control and quality assurance testing. The IDEAL-CT is a simple and efficient test that can be performed with regular indirect tensile strength test equipment.

Watch this video to learn more about IDEAL-CT testing and complete the below form to aggregate IDEAL-CT data.

Use this spreadsheet and corresponding informational PowerPoint to guide you through mix preparation.

Test Information

Two variables that need to be captured reference the “lag time” (the time between sampling and compacting the gyratory specimens) and “dwell time” (the time between compacting the gyratory specimens and testing them).

The recording of this information is to help determine the impact of intended and unintended aging. Please complete the information below to the best of your knowledge. Record the time in hours.
