Specifications include, but are not limited to: The rocking of approximately 38.7 miles of county-maintained dirt roads throughout Colleton County. The project is comprised of fifty-five (55) roadways. At each location, the road is to be fine-graded to ensure proper cross-slopes. Driveway pipes as well as cross-line pipes are to be replaced as specified in the plans. Once the drainage has been improved, an approved rock base material (one that meets SCDOT spec) will be placed and compacted. Road widths and cross-slopes vary and are specified on the plans. Driveways will be rocked to the ROW line (50” ROW typical). The width of the driveway is to be 12’ unless the existing is with than match existing. Grass will be used on the shoulders of the roadway where the existing road is wider than the proposed rock surface as noted.
