Executive Summary:
This project is part of the on-going effort of the Board of Supervisors (Board) to address the road rehabilitation and preservation needs of the County Road System. On May 21st, 2019, the Board approved a two-year pavement preservation program for FY 2020-21 designed to improve approximately 51.50 miles of county roads. The total estimated cost of the plan is $36,719,330, including contributions from the County’s General Fund and revenues derived from SB1.
One element of the 2020-21 program is the 2021 Pavement Preservation Program - Full-Depth Reclamation and Overlays project, C21401, to be constructed in 2021. This project will award a single contract to apply various treatments to 26.76 miles of existing County roads, including one road that was scheduled but not completed during the 2019 construction season - Cazadero Highway (PM 13.61 to PM 16.39); and one road that was scheduled but not completed during the 2020 construction season - Todd Road (PM 11.87 to PM 13.29).
The Department of Transportation and Public Works (TPW) recommends award of the construction contract for the 2021 Pavement Preservation Program - Full-Depth Reclamation and Overlays Project, C21401 to low bidder Ghilotti Brothers, Inc.
On May 25, 2021, TPW will be presenting the next two-year Annual Pavement Preservation Program for FY 2021-22 and 2022-23, which will include Infrastructure Resiliency Plan Tier 2 road projects.
Discussion:
2021 Pavement Preservation Program - Full-Depth Reclamation and Overlays Project, C21401, is Part 3 of the two-year 2020-21 Pavement Preservation Program. The project consists of multiple treatment applications including: Full-Depth Reclamation, Asphalt Concrete Overlays, and Asphalt Concrete Remove & Replace treatments as well as associated flagging, traffic control, crack sealing, ditch cleaning, pavement delineation, and replacement of asphalt concrete surfacing (digouts) as required. Drainage improvements are also included in this project.
The Full-Depth Reclamation (FDR) treatment process involves milling the existing road down one foot below the surface, processing the asphalt concrete base and underlying base with a binding additive to create a homogeneous stabilized base course and compacting the processed mixture back into the roadway. A typical 3.0” asphalt concrete overlay surface is then placed on top of the recycled asphalt concrete layer. This treatment will be applied on the following roadways totaling 9.77 miles shown on the Location Map.
