Certainly. Nevertheless, considering the fact that Superpave mixes do tend to be coarser and consist of modified binders than traditional mixes, superior construction procedures tend to be more essential than previously. Segregation is more more likely to arise with coarser mixes if good gear and tactics aren't applied. Density will also be more difficult to realize with Superpave mixes.
