<body><div>(KNZA)--Representatives of St. Joseph, Missouri-based Herzog Contracting Corporation meet with the Doniphan County Commission Monday to discussed issues that developed following a road overlay project in May. The company installed a two inch overlay on 240th Road, east of the Highland city limits, on May 10th. According to the unofficial meeting minutes, reports were made of the asphalt overlay blistering. Upon inspection it was determined moisture in the chip seal subsurface was escaping due to high heat air temperatures at the same time as the asphalt was applied, thereby trapping the moisture in the asphalt. Herzog representative Kyle Phillips told Commissioners the company inspected the road when they received initial word of the blistering and again recently. The road has since laid back down and Herzog does not expect any further issues. However, during the next heat wave, representatives of Herzog will re-inspect the road. County Attorney Baskins asked what actions would be taken if after the winter months the road is left with potholes. Bryan Jones with Herzog said he did not foresee that happening, but if the road breaks up it may be necessary to wedge or mill and then overlay the road. He also recommended a 1” asphalt overlay in the future to extend the life of the road. According to project specifications, the road has a 1-year warranty for workmanship.</div></body>
