FORT WAYNE, Ind. (WANE) Motorists can expect intermittent lane restrictions during daytime hours on US 30 between Doyle Road and the Indiana/Ohio state line on Wednesday, May 7, as Indiana Department of Transportation (INDOT) crews begin what’s called microsurface construction.The work is expected to last through mid-June.
According to INDOT, microsurfacing is a thin, polymer-modified asphalt emulsion mixture that provides a new wearing course over aged and oxidized pavement. It is applied in a two-step process. First, a fluid asphalt leveling course is put down. A slurry mix of asphalt and aggregate is then applied. The treatment fills ruts in the pavement and improves friction. No compaction is necessary for this method of pavement preservation, and it takes about 1 to 2 hours to fully cure and reopen to traffic. Micro-surfacing is a cost-effective restorative measure that extends pavement life by sealing the roadbed from damage caused by moisture and UV rays.
