Chip Seal Projects Awarded for Routes in Audrain, Boone, Monroe & Shelby County

MACON – The Missouri Highways and Transportation Commission recently awarded a contract to Emery Sapp & Sons, of St. Louis, Missouri, for chip seal projects in Audrain, Boone, Monroe & Shelby County in the amount of $1,714,365. The projects are as follows:

Missouri Route 15 (Audrain & Monroe) – from Monroe County Route D to 1.1 miles north of Missouri Route 22 near Mexico

Audrain County Route KK – from Audrain County Route B to U.S. Route 54 near Laddonia

Missouri Route 151 (Audrain, Boone, Monroe & Shelby) – from 0.30 mile north of U.S. Route 36 in Shelby County to Missouri Route 22 near Centralia

“Crews will be applying liquid asphalt that helps seal off any cracks that may be in the road, and will then will apply small aggregate rock,” said MoDOT Area Engineer Brian Untiedt. “This treatment helps extend the life of the routes,” he added.

A chip seal can be accomplished without closing a road; however, it is extremely important drivers significantly reduce their speed during and immediately after the operation.  Excess rock is swept away by crews shortly after the operation is complete.  Typically, within a few days, the rock has either been embedded into the oil or removed from the surface.  The purpose of this operation is to keep a road in its same condition by infusing it with oil. 

Traffic will be reduced to one lane through the work zones while the work is completed. The work could begin as early as this spring and should be completed before next fall.

“A more specific schedule on these projects will be shared after the contractor provides the plan for completing the work,” Untiedt added.
