What is Ultra-Thin Bonded Wearing Course?

Ultra Thin Bonded Wearing Course (UTBWC) is designed for use as a high performance surface treatment over structurally sound asphalt or concrete pavements. This treatment is used to correct surface distresses, such as raveling or cracking, to restore a smooth surface.

The Ultra-Thin Bonded Wearing Course Process:

The UTBWC process consists of a heavy spray application of polymer modified asphalt emulsion followed immediately by an ultra-thin gap-graded hot mix asphalt. Both applications are quick completed in one pass by a specially designed paving machine. Once the hot mixed asphalt is placed, a 10-ton steel wheeled vibratory roller is used for compaction. The area can be opened to regular traffic usually within 15 minutes after compaction is completed.
