Asphalt Binder Cracking Device to reduce Low Temperature Asphalt Pavement Cracking
INTRODUCTION
There were four tasks stated in the EZ Asphalt Technology Phase 1 proposal:
- Task 1: Refinement of Test Procedures
- Task 2: Field Validation of ABCD
- Task 3: Refinement of Equipment and Analysis Software
- Task 4: Ruggedness Test
The tasks have been completed and are discussed.
In January of 2008, a new testing facility for EZ Asphalt Technology, LLC, was established at the Ohio University Innovation Center. Two technicians were hired and trained to perform ABCD tests and other tasks required for this agreement. For ABCD tests to be performed in Tasks 1, 2, and 3, the following four asphalt binder groups (total of 22 asphalt binders) were used as shown in Tables 1 through 4.
