There are no plans to add the capability. The vast majority of pavements contain no more than three asphalt layers – surface, intermediate/binder, and base. To incorporate a layer such as a friction course, then then user can combine the surface and intermediate/binder layers into a single layer with a set thickness (i.e., 3, 4 or 5 inches) and layer coefficient (i.e., 0.45). The application will use this information to calculate the required base asphalt thickness to meet the predicted traffic and subgrade soil strength.
