TAM – Impacts of Heavy EVs and Hybrid Vehicles on Transportation Asset Management

Description

Literature Search Summary

• ISO 15686-5:2017: Buildings and constructed assets — Service life planning — Part 5: Life-cycle costing
• Whole life carbon assessment (WLCA) for the built environment (rics.org)
• Bus weight summary from the California Air Research Board: https://www.arb.ca.gov/msprog/bus/busaxleweightlimit.pdf

• FHWA Sustainable Pavements Program: Sustainability - Pavements - Federal Highway Administration (dot.gov)

Objectives

The objective of this study is to develop a guidebook with suggestions for updating asset management models used in pavement and bridge design and preservation. The guide will be developed from research to determine:

• The impacts of EVs and hybrid vehicles on typical pavement and bridge (component and element) deterioration rates and their potential impact on lifecycle planning strategies.
• Environmental and societal impacts associated with the use of EVs and hybrid vehicles to support a triple-bottom line analysis and cross-asset tradeoff assessments.
• Suggested modifications to pavement and bridge load models used in design activities.
• The feasibility of establishing battery weight limits, increased road user fees, or other strategies for addressing asset management impacts.

The guidebook will be supported by case studies from a variety of agencies (state and local, urban, and rural) illustrating the potential impact the resulting deterioration rates would have on pavement and bridge designs, maintenance strategies, and lifecycle costs.

Urgency and Potential Benefits

This project would benefit the entire bridge and pavement community by helping them to prepare for future EV and hybrid applications. Having quantifiable AM models that predict accelerated deterioration rate, will help to inform design considerations, transit and freight routes, future funding needs, and support conversations between DOTs and Transit agencies for future service level planning.

Implementation Considerations

The report would benefit from case studies for each pavement and bridge category including local, state, and county agencies representing high and low volume roads / bridges along with rural and urban settings.
