MnDOT tests structural synthetic fibers for use in thin ...

2019-1-30  Lab testing demonstrated that structural synthetic fibers in thin concrete overlays keep cracks tight and help transfer loads across pavement slabs. Researchers provided recommendations for selecting fiber types and dosages in pavement design. In the final step, researchers analyzed the collected data and developed recommendations for MnDOT.

TLN - Early-Age Fiber-Reinforced Concrete Properties for ...

When selecting an appropriate fiber-reinforced concrete for the design of thin overlays, the flexural residual strength is the primary design criteria used. One major challenge with the FRC industry and use in pavements is that the test does not specify when (age of overlay) these tests should be performed.

Why Structural Fiber is the Smart Choice for Thin Concrete ...

2021-9-13  Thin concrete overlays are one such economic rehabilitation alternative for moderately distressed concrete and asphalt pavements. The thickness of these types of concrete overlays varies from 3-6 in. When the thickness is less than or equal to 4 in., they are referred to as ultra-thin overlays; otherwise they are known as thin concrete overlays.
