Board weighs pilot of "triple treatment" tar-and-aggregate laminate to cut dirt-road maintenance
Summary
Commissioners heard from staff about a multi-layer tar-and-aggregate "triple treatment" used by neighboring counties to stabilize low‑volume dirt roads; commissioners recommended piloting a few roads, noted right‑of‑way and equipment constraints and requested further analysis and cost estimates.
County staff and commissioners discussed whether Haralson County should test a multi-layer tar-and-aggregate treatment—described in the meeting as a "triple treatment"—on select dirt roads to reduce recurring maintenance costs.
Staff described the process as a laminate of oil/tar and aggregate applied in layers to produce a base that can last five to seven years before overlay. A commissioner who had spoken with a neighboring county reported that the other county saved about 27% per year on maintenance on roads where the treatment was used.
Commissioners emphasized the approach would not be appropriate for every road, citing traffic, right‑of‑way availability and lead-time for specialized equipment. The idea advanced as a multi-year pilot: choose a limited number of roads annually, obtain right‑of‑way where necessary, and measure long-term savings compared with current maintenance cycles. Staff and commissioners agreed to continue research, seek cost estimates and identify candidate roads for a pilot program.
