Specifications include, but are not limited to: 1) Paving Lift Requirements and Time Limitations: For paving lifts of 2.0 inches or less, bring all newly resurfaced lanes to the same station and elevation within 72 hours. If not brought up to the same station and elevation within 72 hours, the Contractor shall place portable “UNEVEN PAVEMENT” signs in advance of the uneven pavement and spaced every 1/2 mile along the section of uneven pavement. Once mitigated, all portable “UNEVEN PAVEMENT” signs shall be removed. No additional compensation will be made for these signs or any other type of portable warning signs as these are included in the “Temporary Traffic Control” contract pay item.; 2) Asphalt Surface Treatments (AST) For AST Operations, there is no drop-off condition to be signed. Stationary “LOOSE GRAVEL” and “UNMARKED PAVEMENT” signs shall replace “LOW/SOFT SHOULDER” signs. For placement and spacing of these signs, see the Signing Detail Sheet. All other advance warning signs are to be portable mounted. These signs are included as part of the temporary traffic control (Lump Sum) item.; 3) Fine Milling/Microsurfacing (Depths less than 1”) For fine milling operations less than 1”, paving is not required in the same work period. The paving of the fine milled area is to be conducted within the next work period and not to exceed 72 hours. No advance warning signs are necessary for these conditions unless the paving operations exceed 72 hours. If this occurs, install portable “UNMARKED PAVEMENT” signs. These signs are incidental to the other items of work included in the temporary traffic control (Lump Sum) item.; 4) Shoulder Drop-Off Requirements Whenever paving operations create an edge of pavement drop-off greater than 2 inches, within 72 hours, the Contractor shall backfill at a 6:1 slope from the edge and finished elevation of the pavement that has an edge of pavement drop-off as follows: (A) Drop-off that exceeds 2 inches on roadways with posted speed limits of 45 mph or greater.; (B) Drop-off that exceeds 3 inches on roadways with posted speed limits less than 45 mph.;
