Optimal Replacement Cycles of Highway Operations Equipment

State highway agency equipment fleet assets are vital to the delivery of agency programs, projects, and services. A variety of practices have been used by highway agencies for deciding on the replacement cycles of highway operations equipment. However, there is no widely accepted process on which to base decisions. Therefore, there was a need to identify current practices, review relevant information, and develop rational processes to provide a realistic means for determining optimal replacement cycles. There was also need to prepare a guide for optimal replacement cycles to facilitate use of these processes. This report provides both a handbook on equipment replacement concepts and an instruction manual for making cost-effective replacement decisions. The research report presents a process for determining replacement needs for highway operations equipment, identifying candidate equipment units for replacement, and preparing an annual equipment replacement program. The products include a guide and an Excel-based replacement optimization tool to support the equipment replacement process and facilitate its implementation. The guide is designed to help fleet managers determine optimal life cycles and implement systematic replacement processes supported by sound data-driven analysis. In this manner, the guide should help fleet managers determine replacement needs and prepare replacement budgets to provide a highway operations program with a high-quality and dependable fleet to support the agency’s mission. The information contained in the research report should be of interest to fleet managers and state maintenance engineers and to others involved in the replacement aspects of equipment fleet assets.
