Pavement removal and replacement including but not limited to, removal of HMA pavement and concrete beam curb and replacement with PCC paving. SURFACE ROUGHENING A. Directional Tracking: 1. Do not use on slopes steeper than 3:1. 2. Operate tracked equipment up and down exposed slope to create ridges perpendicular to the slope. 3. Continue operation until the entire surface has been tracked. B. Grooving/Furrowing: 4. May be used on all slopes. 5. Use rippers, disks, harrows, chisel plows, or other equipment capable of operating on the slope and creating grooves a maximum of 15 inches apart and 3 inches deep. 6. Operate equipment along the contour of the slope to create grooves that are perpendicular to the slope. 7. Perform over all exposed slopes as specified.
