About this file
This document is a set of engineering drawings for a service road rehabilitation project in Yosemite National Park. The drawings detail the design for reconstructing approximately 1,000 linear feet of service road, including horizontal and vertical alignment, typical road cross-sections, and pavement structure. Key technical specifications include a 5-inch asphalt pavement section with two layers: a 3-inch polymer-modified intermediate binder course and a 2-inch stone mastic asphalt (SMA) surface course. The project also includes a high-friction surface treatment, a 6-inch minimum crushed aggregate base course, and a safety edge detail.
Material quantities for the project include 140 tons of SMA surface course, 210 tons of polymer-modified asphalt binder course, 1,250 square yards of high friction surface treatment, and 440 cubic yards of earth moving/excavation. The road design involves complex horizontal and vertical curves, with superelevation transitions and grades ranging from -21.34% to 8.96%. The project is located in the El Portal area of Yosemite National Park and involves rehabilitating an existing service road while preserving existing site features and minimizing environmental impact.

1. THE SAFETY EDGE WILL BE CONSTRUCTED AS PART OF THE ROADWAY
PAVEMENT. A SHOULDER WEDGE DEVICE WILL BE ADDED TO THE SCREED
OF THE PAVING MACHINE.
2. THE CONTRACTOR MAY USE A SHOULDER WEDGE MAKER OR A SIMILAR
DEVICE THAT PRODUCES THE SAME COMPACTION RESULTS.
3. SHORT SECTIONS OF HANDWORK WILL BE ALLOWED WHEN NECESSARY
FOR TRANSITIONS.
4. SITE PREPARATION AND ADDITIONAL EARTHWORK REQUIRED TO
CONSTRUCT THE SAFETY EDGE WILL NOT BE PAID FOR SEPARATELY BUT
SHALL BE INCLUDED IN THE WORK.
