This document is a set of engineering and construction plans for the Pinellas County Public Works Department's FY2025-2026 Countywide Pavement Preservation Program, specifically focusing on Keene Road from East Bay Drive to Belleair Road. The project involves milling and resurfacing approximately 7.62 lane miles spanning 472,308 square yards, with a total estimated project cost of $1,110,216. The project includes comprehensive road restoration techniques such as milling existing asphalt pavement to a depth of 2 inches and applying a new Type SP 12.5 Structural Course (Traffic C) surface layer, also 2 inches deep. The design incorporates detailed plans for road markings, lane configurations, and maintaining proper road crown and drainage.

The project documentation includes extensive technical specifications for road reconstruction, including precise guidelines for milling, resurfacing, pavement marking, utility coordination, and traffic management. The plans detail core sampling results, typical road sections, and specific requirements for shoulder stabilization, inlet protection, and loop detector positioning. Eight core samples were taken to assess existing pavement and base conditions, with variations noted in top lift, middle lift, and bottom lift thicknesses. The project will involve carefully managing existing utilities, maintaining traffic flow, and ensuring proper surface elevation and drainage, with all work to be completed according to Pinellas County and Florida Department of Transportation standards.
