ADB BRIEFSSustainable Funding for Road Maintenance KEY POINTS• Developing countries in Asia and the Pacific underfund road maintenance by 40% on average. • Funding challenges will continue as costs rise from aging and expanding road networks and extreme weather events.• Road asset management systems and efficient contract management practices enable effective road maintenance.• Disclosure of financial and performance information promotes transparency, and engagement of citizens and advocacy groups sustains road investments and maintenance. • Road funds need good governance; and road user charges, where feasible, could augment funding.• Public–private partnerships can leverage private sector funding, technology, and expertise for construction and maintenance of large road networks.Julitta PonniahPrincipal Financial Management Specialist Financial Management Division (PFFM) Procurement, Portfolio, and Financial Management Department (PPFD) Asian Development Bank (ADB)Anshuman BardhanSenior Financial Management Officer PFFM, PPFD, ADBJannine CeriloFinancial Management Analyst PFFM, PPFD, ADBOVERVIEWThis brief examines sustainable funding for operation and maintenance (O&M) of roads through the lens of public financial management (PFM). Various studies have shown that regular and proper road maintenance can extend road life-span reduce future costs of road rehabilitation, and decrease vehicle operating costs. Nevertheless, many countries underfund road maintenance due to budget constraints. This is a recurrent issue that is common across infrastructure projects and is significantly impacting the sustainability of projects financed by the Asian Development Bank (ADB) in the region, which declined to 56% in 2024.1 Based on a review of over 60 project completion reports of ADB-financed road projects, this brief identified six most common measures used to address the issue of road maintenance and analyzed their adequacy in ensuring sustainability of Notes: In this publication, “$” refers to United States dollars.

Applying a PFM lens, these measures were examined as to how they help to plan, fund, manage, and report on road maintenance.The brief concludes that financial sustainability of roads will remain a challenge due to chronic underfunding. Therefore, measures to improve financial sustainability should extend beyond project-specific int
