AASHTO R 15-18 covers the laboratory testing required to evaluate asphalt additives and modifiers in both neat asphalt and in asphalt-aggregate hot mixtures. The terms “additive” and “modifier” are used interchangeably and are broadly interpreted to include any materials added to asphalt binder in minor amounts, other than mineral fillers, sand, and aggregates, whose purported effect is to improve the performance and service life of pavements or maintenance materials by improving the properties of the asphalt binder or hot-mix asphalt or both.
