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 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.
Sunland has executed nearly 30 UTBWC projects totaling over $14 million in the last ten years throughout the state of Arizona. Contact our experts today to see if this pavement maintenance solution is right for your project.Contact Our Experts
