Attachment_1_Polymer_Overlay_Transition_detail.pdf

The document is a technical drawing detailing a Polymer Overlay Transition Detail for a highway project in Dane County, Wisconsin, specifically for West Broadway. The drawing, created by WisDOT (Wisconsin Department of Transportation) and labeled with sheet number 42, illustrates a precise engineering specification for road/bridge deck overlay work. The technical drawing shows a cross-sectional view of a pavement/approach slab transition, featuring two lifts (first and second), a 3/8-inch maximum depth milling specification, and a detailed deck joint transition area. The project number is 79000-2200, plotted on 4/21/2022 by Jeremy Rach.

The drawing provides a precise engineering specification for a polymer overlay transition, demonstrating a technical approach to road surface renovation. The detailed cross-section reveals a gradual transition methodology between the approach slab/pavement and the deck, with specific attention to milling depth, overlay layers, and joint integration. While the drawing does not include pricing or comprehensive project details, it represents a technical component of a broader highway infrastructure improvement project in Dane County, Wisconsin, likely part of a state-level transportation infrastructure maintenance or enhancement initiative.
