Taxiways C & D Pavement Rehabilitation Project

The Holt Design Team analyzed values from a previously conducted Pavement Condition Index (PCI) and developed a phased multi-year pavement repair plan for the airfield. The 2021 projected PCI values identified parallel Taxiway Delta and associated connectors and partial parallel Taxiway Charlie as needing either rehabilitation or replacement of the asphalt surface. The Airport also decided to include the pavement replacement of the West Ramp as a Non-AIP bid schedule to the project due to the close proximity to Taxiway Delta.

The base bid work included approximately 23,400 SY of asphalt rehabilitation. The remaining base course was proof-rolled to determine any soft or yielding areas. Areas of base failure were addressed by adding cement to the existing base, then mixing and compacting as a reclaimed base course. New asphalt surface courses (3” light duty, 4” medium duty) were then constructed. Due to reduced cement reclamation areas required, approximately 2,700 square yards of additional Charlie and Delta pavement areas were replaced adjacent to Runway 1-19. An additive bid addressed Taxiways Charlie One and Charlie Two and included 2,600 SY of pavement area. The additive bid West Ramp pavement reconstruction was funded by an SCAC grant and included approximately 9,300 SY of asphalt and base replacement on the ramp that supports two airport tenants. During West Ramp construction, the owner added ten (10) aircraft tiedown positions (30 tiedown anchors total).
