Some New Castle County roads will have intermittent lane closures this month while the Delaware Department of Transportation carries out a microsurfacing project.

The affected roads will be closed from 8 a.m. until 4 p.m., weather permitting. The contractor for the project, Asphalt Paving Systems Inc., will be placing notices on the doors of affected residences and businesses to notify them of the dates.

Microsurfacing is a thin, tough layer of asphalt emulsion containing aggregate rocks, water and mineral fillers, according to DelDOT. It is used to seal cracks and prevent moisture from penetrating the road base.

The first phase of the project will begin May 7 and 8 on Caldwell Corner Road.

Massey Church Road will be done May 9, Marl Pit Road May 10 and 11, Brick Mill Road on May 14, Kirkwood – St. Georges May 15 and 17 and Frazer Road May 17 and 18.

About half a road is closed for the project at a time and the length of time the road is closed depends on the air temperature and humidity and how many passes of microsurfacing is applied.

Once the material is applied to the road, it takes bout an hour to settle in before it can be ridden or walked on.

The material, which is also being used to patch up roadways across the state, creates a smooth surface on the road without having to do a large scale and costly overlay project.

Local residents and emergency response vehicle will be able to access roads at all times during the closures.
