For Pavement Condition

(PCI of 70 or greater)
An ultra thin lift HMA is a hot mix asphalt treatment consisting of paving grade asphalt and aggregate. Ultra thin lift asphalt treatments are generally applied at a compacted depth of .75” to 1” on roads in good condition. This pavement preservation application provides a smooth surface, while addressing raveling, low-severity top-down cracking and oxidation.
- Higher initial cost compared to other preservation treatments especially if milling is required; however, ultra thin lift asphalt will help reduce life cycle cost and extend agencies limited budgets.
- While not as environmentally friendly as other pavement preservation processes, ultra thin lift HMA's reduce GHG Emissions by up to 25% per year compared to a 2" Mill and Fill depending on specific thin lift treatment. (1)
- Material is 100% recyclable
- Quick return to traffic
- Adds 8-10 years (when applied for optimum preservation performance) depending on specific ultra thin-lift treatment
Issues Addressed
- Low-Severity Cracking
- Raveling
- Friction-Loss
- Oxidation
- Retards further deterioration of pavement
Attributes
- Protects the surface from oxidation.
- Restores road profile (within limitations)
- Maintains grade and slope
- Overlay for existing concrete pavement (spray paver recommended).
- Addresses minor distresses such as low-severity cracking (<1/4")
Common Combinations
- Ultra Thin Lift HMA and Crack Seal
- Ultra Thin Lift HMA and Chip Seal
- Ultra Thin Lift HMA and Scrub Seal
- Ultra Thin Lift HMA and Micro Milling
