Paving progress on F31 keeps October completion date firm


The repaving of County Road F31 — the Minburn Road — from Minburn eastward to County Road R22 has passed the halfway point and is on schedule to meet its estimated completion date in early October, Dallas County Engineer Al Miller said Tuesday.

Work began on the six-mile stretch of country blacktop May 23, with subdrain work followed by the removal and crushing of the existing pavement.

The $4 million paving project is in the hands of Brooklyn, Iowa-based Manatts Inc.

Manatt’s began stabilizing the roadway in mid-July with fly ash in Minburn. Fly ash is a very fine, powder-like material that stabilizes and strengthens the road when mixed with water and soil, according to Miller. He said the material was mixed with the old road and then recompacted.

During the stabilization phase, flaggers were used to close the road near the work, and cooperative weather kept the phase within the estimated three to four weeks.

Paving began in mid-August and is expected to take about three weeks, according to Miller. He said through traffic should continue to follow the marked detour routes of U.S. Highway 169, Iowa Highway 44, and County Road R30. Access is being maintained for local traffic only.
