About this file
This is a technical specification document for Type A Drive Approach construction standards prepared by Bountiful City, Utah, in conjunction with a broader street improvement project involving sidewalk, curb and gutter, drive approaches, waterways, and storm drain facilities at random locations throughout the city. The specification establishes detailed requirements for drive approach construction, including concrete specifications (Class 4000 per APWA standards), dimensional requirements (12 feet minimum to 30 feet maximum length, 6 inches minimum thickness), reinforcement specifications (2 #4 continuous bars), and base preparation requirements (6 inches road base minimum with 95 percent compaction of existing subgrade). The document includes sectional and plan view diagrams illustrating both radial and California flare options for curb transitions, with specific notes regarding expansion and contraction joints, asphalt saw-cutting requirements, and curing procedures.
The specification requires epoxy-coated rebar, straight metal forms for tangent sections or curb radii exceeding 150 feet, and full-depth saw-cutting of existing concrete or asphalt materials to be removed with a minimum 3-foot width of asphalt removal in front of drive approaches. Concrete placement and curing must comply with current APWA (American Public Works Association) specifications, with curing achieved through application of curing compound per current standards. The document was revised in August 2017 and serves as the standard template for all Type A drive approach construction work within Bountiful City, ensuring consistency and quality across the random location improvement project.
