What is Fiberized Micro Seal?

Fiber Reinforced Micro-surfacing (or slurry seal) is a cost-effective preventive maintenance that consists of a thin layer of a polymer modified asphalt emulsion blended with finely crushed stone and high strength glass fibers. The purpose of this treatment is to seal minor cracks and improve reflective cracking resistance and lead to superior flexural durability.
