State of Oklahoma Field Divisions
Demo Scrub Seal Project Location Field Division 3 SH-19 Near Ada, OK
Scope Scrub seal a one mile roadway section Supplier operated brush trailer with ODOT providing labor and chip operations
Date of Project Summer of 2016
Heavily Distressed
Horizontal Curve
Segment with Crack Seal - Removed Prior to Scrub Seal.
Finished Product
Overlap and Ridges
Variable Depth Areas
Scrub Seal Project
What we learned Horizontal curves made it difficult to keep the oil even across the lanes. Maintenance crew had to hand brush the oil from the low point back to the road surface Inconsistencies in areas being treated caused the formation of longitudinal overlapping of oil and chips
Finished Product
Micro-surface Project
Location Field Division 4 SH-3 in Canadian County, OK
Scope Micro-surface a 15 mile roadway section
Date of Project Fall 2009
What Went Wrong?
Contractor got off to a slow start and had to redo some areas. Rough texture and inconsistency brought attention. Public became aware and unhappy with product and project intent.
Numerous Thermal Cracks
Some are very extensive.
Micro-surface Project What we learned Pick a more suitable candidate roadway sections for thin treatments. Public has expectations when they see work going on. Slow start and un-remedied bumps at cracks brought attention that started a media frenzy. Due to the pavement condition, the roadway section was a better candidate for minor / major rehabilitation Micro Surface is performing well at 8 years of age. Best road there is between the thermal cracks.
