Route 19 in Gasconade County Pavement Improvements
Project Details
When:
The project took place in 2020.
Cost:
$416,465
Work Taking Place:
Seal Coat Overlay on Route 19, between Hermann and U.S. Route 50.
A seal coat operation entails spraying a heated film of asphalt liquid on the road, followed by placing fine rocks or chips on top. The chips are then compacted to make them adhere to the roadway. Finally, the excess loose chips are swept from the surface, leaving an improved roadway that will hold up longer than it would have without the treatment.
Seal coats are about one-third the cost of a conventional asphalt overlay, averaging $15,000 per mile as compared to an estimated $55,000 per mile for an asphalt overlay. Seal coating keep damaging water from penetrating paved surfaces and extend the life of the pavement for an additional five to seven years. Roadway traction is also improved.
Project Milestones
In January 2020, the Missouri Highways and Transportation Commission awarded a contract to Blevins Asphalt Construction, which submitted the low bid of $416,465.
