State of Alaska has published four final reports on Geotechnical Asset Management. The description and link to the each report is below.
Geotechnical Asset Management Plan Paul D. Thompson - 30-Jun-2017 This Technical Report provides a detailed analysis of relevant performance objectives and measures; the inventory and current conditions of geotechnical assets; methods to compute and minimize life cycle cost; methods to manage risk; and the Departments financial plan and investment strategies for its geotechnical assets. The report provides the technical background for a continuing process to improve the Departments geotechnical risk management capability.

Geotechnical assets included rock slopes, unstable soil slopes, and retaining walls. Assessment of these assets adhered to the procedures developed and tested here and in the concurrent statewide Geotechnical Asset Management (GAM) program. The research utilized existing pavement and bridge ratings. Culvert ratings followed a simple observation-based evaluation of culvert function.

Benko, C.P.G.; Aine E. Mines, P.E.; Lawrence A. Pierson, C.E.G.; Paul D. Thompson; Robert E. Kimmerling, P.E. - 05-Sep-2017 The Alaska Department of Transportation and Public Facilities (AKDOT&PF) has developed the nations first Geotechnical Asset Management Program. The program encompasses rock slopes, unstable slopes and embankments, retaining walls, and material sources along the States highway system. Like bridges and pavements, geotechnical assets are subject to deterioration and when not actively managed, maintained, and mitigated; high life cycle costs, reduced mobility, and life-safety risks are the unfortunate result. This proactive program has inventoried and assessed the condition of 1,636 slopes on the National Highway System (NHS) and select portions of the Alaska Highway System (AHS), or about 45% of AKDOT&PFs road miles. Assessments of over 400 retaining walls on portions of the NHS and AHS, or about 17% of AKDOT&PFs inventory, are in the program. Geographic scarcity of quality aggregate materials is assessed on a Maintenance Station basis. All assets are evaluated within a consistent rubric of five condition states and classified in terms of Good, Fair, or Poor condition. Life cycle cost estimation and investment analysis, using first-of-its-kind condition-based programmatic cost estimation, deterioration rates and maintenance costs permit the Department to make informed decisions, all in terms of hazard, risk, and cost as stewards of the Public trust.
