About this file
This is a technical standard sheet document issued by the Connecticut Department of Transportation (CTDOT) on October 23, 2024, and approved on January 29, 2025, providing specifications for bituminous concrete sidewalk, driveway, and pavement construction in Newington, Connecticut. The standard sheet (HW-922_01) details construction specifications and design requirements for multiple pavement types, including bituminous concrete sidewalks with 5-inch HMA S0.5 (Traffic Level 2) installed in 4-inch lifts over 12-inch granular fill, bituminous concrete driveways with 3-inch HMA S0.375 (Traffic Level 1) over 8-inch granular fill, and driveway ramps constructed in two equal lifts. The document establishes grade limitations of 8 percent maximum for commercial driveways and 12 percent maximum for residential driveways, with sidewalk slopes typically at 1.5 percent and maximum slopes of 2 percent. Multiple plan and elevation sections provide detailed dimensional specifications, including 6-inch curbing heights, 1-inch driveway lips, and transition requirements between curbing and driveways, with radius specifications ranging from 2 feet minimum to 50 feet maximum for various applications.
The standard sheet serves as a technical reference document for construction projects related to the City of Bridgeport's Citywide Sidewalk, Curb, Apron & ADA Ramp Repair and Replacement initiative, with electronic bid submissions required through the City's OpenGov Procurement Portal by 2:00 pm on Tuesday, September 22, 2026. The document was prepared by Leo Fontaine, P.E., and approved by Michael N. Calabrese, P.E., of CTDOT's Office of Engineering. Bidders must review the standard specifications and any issued addenda posted on the procurement portal, with the question submission deadline set for 5:00 pm on Tuesday, September 8, 2026, providing contractors with clear technical guidance for project execution.
