tack coat is normally applied to an existing pavement surface before a new layer of HMA is placed. This is done whether the existing surface is an old asphalt concrete layer or a portland cement concrete (PCC) pavement. In some cases, a tack coat is applied to a new HMA pavement layer before the next ...

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.
