Title: Development of Three Point Bending Cylinder (3PBC) Asphalt Mixture Fatigue Test System
Accession Number: 01847986
Record Type: Monograph
Record URL: Abstract: Fatigue cracking is one of the dominant distress types that a pavement structure experiences throughout its service life. The current fatigue cracking tests are lengthy, cumbersome and expensive. Extensive material requirement for sample preparation, difficulty in meeting air void target, a large number of samples needed for testing, common premature ‘end-failures’ (leading to excessive sample preparation time and consumption of material), and high equipment cost are some of the challenges encountered when running these tests. To overcome some of these shortcomings, researchers from the Advanced Asphalt Characterization Laboratory (AACL) at Michigan State University (MSU) developed a new test method called the ‘three-point bending cylinder (3PBC) test’. The primary benefit of this test method is that sample preparation and testing times are shorter than typical fatigue tests (e.g., four-point bending and uniaxial fatigue) and the test fixture is easy to operate and inexpensive. This project was performed in two stages with multiple tasks.
