This document is a "Final Pavement Report" for the "CA NP MOJA 11(2) 10(2) Kelso-Cima and Kelbaker Roads" project in Mojave National Preserve, San Bernardino County, California. It was prepared for HDR, Inc. by GeoEngineers, Inc. and dated February 27, 2024.

This report details the geotechnical engineering evaluation for the rehabilitation or reconstruction of existing asphalt concrete pavement on the Kelso-Cima Road (approx. 19 miles) and South Kelbaker Road (approx. 23 miles).

Key elements include:

• Site Conditions: Surface and subsurface conditions, including pavement condition surveys (fatigue cracking, block cracking, edge cracking, longitudinal cracking, transverse cracking, potholes/patching), subsurface exploration (borings, pavement cores, DCP tests), laboratory testing, existing pavement thickness, subgrade soil characteristics, groundwater conditions, and climate data.
• Conclusions and Recommendations: Pavement design alternatives (full-depth reconstruction, full-depth reclamation with cement, full-depth reclamation without cement), analysis methods (AASHTO 1993 Pavement Design Guide), recommended pavement rehabilitation treatments, and life-cycle cost analysis (LCCA).
• Materials: Recommendations for asphalt binder (PG 70-10) and suggested pay items for the proposed structural section.
• General Considerations: Paving and construction considerations, drainage, and corrosion considerations.
• Appendices: Include field explorations, laboratory test results, pavement core photographs, pavement design calculations, and report limitations.

Other / Unclassified

This memorandum provides recommendations for the rehabilitation of the 15.0-mile Morning Star Mine Road within the Mojave National Preserve, San Bernardino County, California. The existing asphalt pavement, applied in 2015, is beyond its design life and is to be converted to a gravel road. This conversion is intended to reduce traffic speeds and mitigate tortoise mortality within critical desert tortoise habitat.

The document details a pavement assessment conducted in November 2019, which found the asphalt to be approximately 22 feet wide with oxidized pavement and various forms of cracking. Subsequent investigations for nearby roads (Cima Road and Kelso-Cima Road) in 2020 and 2023 provided subgrade soil data (silty and clayey sands) with average R-Values of 54.

The recommended surfacing is 6 inches of Aggregate Base over Full Depth Reclamation (FDR) of the existing asphalt, pulverized to 1-inch below the pavement. This design is based on the South Dakota Catalog Method for a "high" subgrade support condition and low daily truck traffic.

Recommended pay items include Aggregate Surface Course Grading H (TON) and Full Depth Reclamation, Method 2 (MILE).

This document outlines the proposed rehabilitation strategy for Morning Star Mine Road, including the conversion from asphalt to gravel. It provides context on the road's condition, the project's objective (reducing tortoise mortality), and the recommended construction method (FDR with aggregate base). Bidders can use this information to understand the scope of work, the materials involved, and the rationale behind the proposed solution. The document also references attached site maps and photos, which would be crucial for site assessment and bid preparation.
