| Abstract | Any grade of phosphoric acid can be used as an asphalt modifier. The stiffening effect is asphalt dependent. All grades of acid will yield similar results. However, the more diluted grades contain water, which may result in foaming problems as the water boils when the acid is added to hot asphalt. The use of crude green acid is not recommended as it contains acid impurities that are likely to cause corrosion of equipment. |
