Thin HMA Overlays - Cost-Effective Solution
Thin HMA overlays, 1 1/2" or less, are cost effective solution for pavement preservation primarily because of their ability to:
Provide improved ride quality Reduce noise levels
Reduce Surface distresses Reduce life cycle costs
Maintain surface geometrics Provide long-lasting service
Thin HMA Overlays should be placed before the pavement deterioration has reached a critical stage, where a more extensive rehabilitation may be required.
Thin HMA Overlays can be expected to provide 10 years or more on existing asphalt surfaces.
The brochure and presentation below are provided to assist you in using HMA Thin Asphalt Overlays. For further information contact Charlie Holland, APAI Technical Director, email@example.com.
