The workshop offers an overview of the cracking test protocol I-FIT developed as a partnership of the Illinois Center for Transportation and IDOT. I-FIT uses the semicircular bending fracture test to determine an asphalt mixture’s resistance to cracking and is now an AASHTO provisional standard (AASHTO TP124 and Illinois Test Procedure 405). When results from I-FIT are combined with results of other performance tests, balanced mixes with optimum durability and rut resistance can be obtained.
