The Development of Initial Asphalt Mixture Acceptance Criteria Using the SCB test and the I-FIT Test
… along with other states have implemented a test to measure rutting resistance. This paper presents research to implement a cracking resistance test to further modify the Superpave volumetric asphalt mixture design method in Arkansas. The Illinois Flexibility Index Test (I-FIT) was the test …

Development of a performance-based test method for quantification of cracking potential in asphalt pavement materials
… in asphalt mixtures, and second, develop a testing protocol to quantify their cracking potential in a way that is scientifically meaningful and economically practical, while ensuring correlation to independent testing. A characterization of varying amounts of recycled content displayed a …

Impact of laboratory simulated aging on asphalt concrete flexibility
… mixes were investigated in this study using the Illinois Flexibility Index Test (I-FIT) after the specimens were subjected to various lab-simulated long-term aging conditions. The flexibility index (FI), an outcome of the I-FIT and a measure of the AC flexibility. decreases consistently after …

Laboratory assessment of asphalt concrete durability utilizing balance mix design
… however, might not be captured by current testing approaches. Therefore, improving the tools available to assess AC durability is crucial. This research studied the laboratory performance of a high-quality Stone Matrix Asphalt (SMA), designed by the Danish Road Directorate, and that of a …

An analysis of impact factors on the Illinois flexibility index test
… may negate any environmental or economic benefit initially obtained from the use of recycled materials. The typical modes of failure for asphalt pavements with high recycled content are thermal cracking or early fatigue cracking. While RAP and RAS contribute a significant amount of recycled …

Balancing asphalt mixes containing recycled materials for optimum field performance
… 12 surface mixes, which have been used by the Illinois Department of Transportation (IDOT) in different rehabilitation projects across the State of Illinois, between 2013 and 2015. These AC mixes contain asphalt binder replacement (ABR) from 15 to 60%, acquired from RAP and RAS, whereas these …

Effect of specimen geometry and test configuration on the fracture process zone for asphalt materials
… to provide environmental and economic benefits by decreasing the use of virgin materials, such as natural or quarried aggregates and asphalt binder, in newly designed asphalt mixtures. However, recycled materials such as reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) …
