Carlisle, PA

Carlisle Borough's Public Works Field Operations Department maintains 58 miles of Borough roads and 18 miles of public alleys. Throughout the year, the department focuses on preservation treatments of existing roads, including crack sealing, base repairs, and pothole repairs. Then beginning in early September (weather permitting), the crews focus on the dry milling and paving of certain sections of road, as well as the microsurfacing of other roads.

Microsurfacing is an application of a liquid asphalt/stone aggregate mixture coating over the road to extend its useful life. This process helps extend the life of pavement quickly and inexpensively. Microsurfacing also cures quickly, allowing the roads to be open to traffic much faster than with traditional paving. The following roads are scheduled to undergo microsurfacing beginning either September 4 or September 8:

• Forbes Drive – Dunbar to Meeting House
• Croghan Drive – Forbes to South End
• Donegal Drive – All
• Shannon Lane – All
• Stewart Drive – Forbes to Cul de sac
• Sussex Drive – Ascot to Meeting House

Dry milling involves the mechanical removal of the top 1 1/2 to 2 inches of existing road surface to remove unsound material and to facilitate surface drainage. After the milling occurs, crews will repave those sections of roads. The millings are also reused in various construction projects for the Borough. The following roads are scheduled to be milled and paved as part of 2020's Street Improvement Project. Work is scheduled to begin on September 2.

• D Street from between Waggoner's Gap & Pitt
• E Street between College & Franklin
• West Street between G & K
