Road Resurfacing

The Volusia County Road & Bridge Division is responsible for maintaining approximately 975 miles of paved roadways. These roads are constructed using flexible pavement designs that vary in asphalt type, base material, and thickness, with an expected service life of 15 to 20 years.  However, pavement longevity is influenced by several factors, including traffic volume, vehicle weight, weather conditions, soil stability, and drainage effectiveness.

To preserve the integrity of its roadway network, Volusia County has established a proactive pavement management program. This program evaluates and prioritizes resurfacing and rehabilitation projects based on condition and need. Funding for these maintenance efforts is provided through local gas tax revenues and approved annually through the County’s budgeting process.

Pavement Condition Assessment

Every three years, the County hires an independent infrastructure consultant to perform a comprehensive pavement condition survey of its paved road network. This assessment includes the collection of high-resolution, continuous imagery of road surfaces, along with an evaluation of surface distresses such as cracking, rutting, and roughness. Based on the analysis, each roadway segment is assigned a Pavement Condition Index (PCI) rating, which ranges from 0 to 100 and reflects both surface condition and structural integrity:

• Very Poor (0–25)
• Poor (25–40)
• Marginal (40–50)
• Fair (50–60)
• Good (60–70)
• Very Good (75–85)
• Excellent (85–100)

According to the July 2024 pavement condition survey, Volusia County’s roadways were generally in Very Good condition, with an average PCI of 76. Approximately 69% of all County-maintained roadways received a rating of Excellent or Very Good.

Why Roads Deteriorate

 Several factors contribute to roadway wear and tear:

• Heavy traffic and vehicles – Lead to rutting, cracking, and surface deformation
• Poor drainage and soil – Cause warping, edge cracking, and depressions
• Sun exposure – Breaks down asphalt binders over time
• Aging asphalt – Reduces flexibility and leads to cracking

Our Rehabilitation Methods

 To extend pavement life and improve ride quality, we use several rehabilitation techniques based on road condition and usage:

• Asphalt Overlay
  A new layer of asphalt, typically 1.25 inches thick, is applied over the existing surface to restore ride quality and extend service life. Severely rutted areas are repaired before the overlay is placed to prevent future defects.
• Milling and Resurfacing
  The existing asphalt surface is milled to a determined depth, typically 1 to 1.5 inches. After cleaning and surface preparation, a new asphalt layer is applied to create a smooth, durable surface.
• Micro-Resurfacing
  A thin asphalt-aggregate mixture is applied to fill minor cracks and seal the surface against moisture. Commonly used in neighborhoods and lower-traffic urban areas, this treatment typically extends pavement life by 10 to 15 years.

Roadway Selection Criteria for Resurfacing

 Primary components include:

• Traffic Volume
  Roads with higher daily vehicle counts—particularly thoroughfares—tend to wear faster and are prioritized over lower-volume residential streets.
• Pavement Condition Index (PCI)
  The PCI provides an objective, standardized assessment of pavement condition based on observed issues such as roughness, cracking, and rutting. Data is collected using specialized survey vehicles equipped with advanced imaging and diagnostic tools.
• Maintenance History
  Roads that require frequent maintenance—such as repeated pothole repairs—are flagged for resurfacing to reduce long-term upkeep costs and improve safety.
