High maintenance costs and continuing inconvenience to the traveling public have forced Iowa to take drastic measures in resolving a long-standing problem on Interstate 80 in western Iowa. It was found necessary to remove a section of asphalt and replace it full width with a portland-cement concrete section 10 in. deep. The removal and replacement operation led to the conclusion that in the future major problems could be corrected by replacement of the 12-ft travel lane only. Construction of the 12-ft travel lane proved to be cost-effective and no major problems were encountered. Through traffic was maintained in the normal passing lane and the contractor was limited to use of the 10-ft outside shoulder only. Included are details of the reasoning leading to the decision to reconstruct the travel lane only. Minor problems associated with smoothness of ride were corrected by use of a heavier finishing machine. (Author)
