Abstract
Application of Fiber Reinforced Concrete (FRC) in constructing concrete pavement overlaysand new concrete pavements is gaining more attention. However, there has been limited
research on quantifying the performance benefits of fiber and its dosage in concrete
pavements, specifically in thin concrete pavements. The present study focused on determining
the influence of synthetic macro-fibers in keeping the joint performance high for a longer
duration of pavement service life and in mitigating thin concrete pavement distresses such as
transverse joint faulting and fatigue cracking. Field data was collected from fiber reinforced
in-service test sections at the MnROAD test facility, located on I-94 westbound, 35 miles
north-west of the twin cities metropolitan area, Minnesota. Field data included, falling weight
deflectometer (FWD), environmental strain, transverse joint faulting, international roughness
index (IRI), and crack survey data. It was found that joint performance was significantly
affected by the inclusion of fibers. High fiber dosage resulted in greater LTE, lower
differential displacement, and lower loaded-side displacement. A faulting prediction equation
was proposed on the basis of faulting data and statistical relationships. A relationship was also
established between the joint faulting and IRI. The distress data analysis indicated that fatigue
cracking may not be the dominant distress of the thin fiber reinforced pavements, but the
transverse joint faulting is.
