ULTRA-THIN WHITETOPPING : 10-YEARS OLD AND GOING STRONG

Ultra-thin whitetopping (UTW) has been used as a means to repair distressed asphalt pavements for the last 10 years, and is now widely accepted as a low-cost, quick and durable repair option. The UTW concept of a composite pavement has been extended, including thicker concrete overlays that are placed over asphalt. The resulting bond between concrete and asphalt permits the layers to share the load and enable the neutral axis in the concrete to shift downward from the middle of the slab to its bottom. Repairs made in the early 1990s have exceeded their design lives. If UTW panels do crack, repairs are generally a simple matter, since panels can be removed and replaced quickly. The article discusses how UTW is also performing well at general aviation airports.
