Site work and paving for a civil project in Youngstown, Ohio. Completed plans call for site work for a bridge / tunnel; for paving for a bridge / tunnel; road / highway; and road / highway.

Proposal Nm: MAH101046 County: Mahoning Four Lane Resurfacing C/R/S: MAH-IR 680-12.12 Completion Date: 7/3/2026 For Improving Various Sections in Beaver and Boardman Townships, Within Mahoning County, Ohio, in Accordance With Plans and Specifications by Planing, Performing Pavement Repairs, and Resurfacing an Approximately 4 1/2 Mile Section of I-680 From Just South of Us 224 to the Concrete Pavement North of the Toll Booth, Including All Related Items of Work. Project Includes Some Bridge Patching and Deck Sealing. OHDOT : Four Lane Resurfacing - IR 680 The surface tolerance specification requirements are modified to use the International Roughness Index (IRI) to determine both lot roughness and localized roughness for Category 1 pavements as follows: o All pavements with at least 1 centerline mile (1.6 km) of continuous paving. Short breaks in paving such as bridge decks, intersections, etc. are not considered breaks in continuous paving. o Pavement for ramps including any associated acceleration lanes or deceleration lanes; auxiliary lanes; or drop lanes, where the total combined length of any one lane is greater than 0.5 miles with a width that allows a valid profile to be collected. o Pavement for system ramps including associated acceleration lanes, deceleration lanes, and auxiliary lanes regardless of total length. "System ramp" is defined as pavement connecting two divided, limited-access highways. The surface tolerance specification requirements are modified to use the International Roughness Index (IRI) to determine localized roughness for Category 2 pavements as follows: o Roads with less than 1 centerline mile (1.6 km) of paving o Pavement for ramps plus acceleration lanes not included above. o Pavement for ramps plus deceleration lanes not included above. o Sections of undivided highways, as defined in this note, within corporation limits with posted speed limits less than 40 miles per hour, For Category 2 pavements, corrective action for all areas of localized roughness with an IRI in excess of 250 inches per mile (3.95 m/km) in 25 feet (7.6 m) is required. For these same areas, no corrective action for 0.1-mile (0.16 km) sections having an MRI (lot roughness) greater than 90 inches per mile (1.42 m/km) is required and no pay adjustments will be made for lot roughness. Do not include pavement for turn lanes including center turn lanes, shoulders, crossovers, approach slabs, and bridge decks in IRI measurements, corrective actions, and pay adjustments. Areas not part of this specification are subject to the requirements of the original item(s) specified. If the pavement surface is Rubberized Open Graded Asphalt Friction Course (Supplemental Specification 803), this specification applies to the surface of the course immediately below and references to the number of courses placed do not include the SS803 course.
