This document is a detailed set of engineering drawings for a road paving project in the Plumas National Forest, specifically Road 22N94 - 3.9 Hot Mix Asphalt Paving. The project is located in Plumas County, California, within the Feather River Ranger District of the Pacific Southwest Region. The drawings include a project location map, travel directions, a schedule of items, and technical road section details.

Key project specifications include mobilization, contractor quality control, public traffic control, and asphalt concrete paving. The project requires placing 2" of compacted asphalt over existing aggregate base and a double chip seal, with strict requirements for mix composition, placement, and compaction. The contractor must provide traffic control, warning signs, and ensure the asphalt surface is laid without cracking or displacement. The total quantity of asphalt concrete is 1,584 tons, and the project involves precise road elevation matching and horizontal alignment control.
