NCHRP 13-08 [Anticipated]

Guideline for Decision Making for Repair vs. Replacement of Highway Maintenance Equipment

  Project Data
Source: AASHTO Committee on Maintenance
Funds: $350,000
Staff Responsibility: Andrew C. Lemer
Comments: This project's initiation is deferred pending progress on NCHRP Project 13-07.
Fiscal Year: 2019

This project has been tentatively selected and a project statement (request for proposals) is expected in August 2018. The project statement will be available on this site. The problem statement below will be the starting point for a panel of experts to develop the project statement.

Equipment failures often force fleet managers to decide if equipment should be repaired or replaced. This may not be solely a financial decision; it is an operational decision as well. Operational impacts such as downtime, loss of function, mission criticality, etc., need to be included. Fleet managers need resources to evaluate the merits of handling both planned refurbish vs. replacement decisions and unplanned repair vs. replacement decisions for equipment that has not met the established life cycle. The repair, refurbish, or replace decision is a consideration for DOT fleets as a method to manage fleet expenditures and extend life cycle. Effective fleet management involves an evaluation of when is the correct time to repair, refurbish, or replace an asset.

Many factors are considered in making these analyses, including equipment and component condition, anticipated asset service life, costs for repair or replacement, equipment reliability, and time the equipment will be out of service for repair or arrival of the replacement. Availability of funds, whether repair or refurbishment, will be accom-plished in house or outsourced; current workloads; and many other factors may affect the repair-or-replace decision.

The objective of this research is to provide fleet managers with a methodology and an electronic tool to guide decisions to repair or replace equipment. The methodology and tool should be suitable for endorsement and distribution as an AASHTO guide. The target audience for this research would be state DOT fleet managers and maintenance engineers who rely upon availability of equipment to carry out day-to-day operations.
