transverse variable spray rates (TVSR). In this technique bitumen spray-rates are varied across the lane width to account for the impact of traffic in the wheel-paths. This leads to designs where higher binder application rates are used on the shoulders and between the wheel-paths and lower rates in the wheel-paths.
