KYDOT Micro Surfacing – Morehead, KY

Morehead, KY - October 2018

Project Description

The Kentucky Department of Transportation (KYDOT) began a control vs fiber test on State Route 519, off US 60, on Baldridge Road using Surface-EXT. The road was applied at a dosage of
23 lb/ sq yd with .2% Surface-EXT and applied at a thickness of approximately 1/4” to 3/8”. Before the application, the road was crack sealed and previously had two different applications
applied to it before the micro surfacing began. Both sides of the road were having problems with cracking and raveling and similar in common distresses. KYDOT chose this new product trial using
Surface-EXT to increase the road’s longevity while reducing the reflective cracking that keeps occurring. Reduced project costs were also important to them. For little cost added to the project, they will add years of life with micro surfacing resulting in a high return on investment.

Key Points
