Abstract
In various embodiments, a multi-application apparatus with two or more applicators may be used to form markings on a driving surface A profileable material may be applied to an area of the driving surface by one of the applicators during a pass of the apparatus by the area to create a first marking. More of the profileable material may be applied to at least a portion of the area by another of the applicators during the same pass to create a second marking. The second marking may have a more varied profile than the first marking. In embodiments, various parameters may be independently controlled during operation of the multi-application apparatus. In embodiments, the markings may be applied such that the profileable material forming the second marking is at least partially fused with the profileable material forming the first marking.
