Is whitetopping limited to use on low traffic volume roads?
Whitetopping has been used effectively on pavements subjected to all levels of traffic, from low-volume roads to high-type urban Interstate pavements. Thickness is often a function of the anticipated traffic loading. As a result, conventional whitetopping has been used successfully on interstates, primary and secondary roads, and intersections, as well as on taxiways and aprons at major airports. The thinner ultra-thin whitetopping (UTW) overlays are commonly used on lower volume roads, such as residential streets. Intersections are also ideal for whitetopping placement, since rutting and washboarding of the HMA pavement is a common problem.
