This research explores using highly modified asphalt (HiMA) mixtures as an alternative to standard materials in furtherance of making perpetual pavements thinner in Ohio. Previous projects on I-77, US Route 30, and US Route 23 have demonstrated that reduced strains were possible with standard materials at greater pavement thicknesses. Thinner and superior pavements with improved binder have the potential to reduce the construction cost of perpetual pavements, despite the higher unit cost of materials. Four test sections containing HiMA with varying base layer thicknesses of 8 in, 9 in, 10 in, and 11 in were installed at the Accelerated Pavement Loading Facility (APLF) in Lancaster, Ohio. To successfully compare the effect of the HiMA in the various thicknesses, the 11 inch section acted as a control with a non-modified base layer. Each pavement was subjected to 10,000 passes of a single axle load of 9000 lbs at two pavement temperatures of 70°F and 100°F. Rutting on the surface of the pavement was measured using a rolling wheel profiler after 100, 300, 1000, 3000, and 10,000 wheel passes, while pavement distresses were found at the bottom of the base and intermediate layers in the longitudinal and transverse directions after wheel passes of 100, 3000, and 10,000 at wheel loads of 6000, 9000, and 12,000 lbs. The serviceability of the pavements was determined by comparing the longitudinal tensile strains within the base layer ofeach pavement to calculated fatigue endurance limits (FEL) found by using flexural stiffness standards from NCHRP Design Guides in addition to Kansas researchers to determine which sections met the perpetual design concept. Following the testing, it was determined that the four test sections showed no significant rutting damages after being subjected to 20,000 passes of a single axle load of 9000 lbs. Additionally, the thinnest section produced maximum average strains higher than the calculated fatigue endurance threshold at 100°F using the NCHRP 9-44A equation; however, using the Kansas researchers approach, all four test sections were found to have lower longitudinal strains than the calculated FEL. The findings from this study have shown that the modified binder provides substantial improvement in rutting but did not show significant improvements in structural support when comparing the modified asphalt to standard asphalt mixtures.
