Summary
Modifiers have been used to improve the performance of asphalt/aggregate mixtures for building roads for over the past hundred years and during that time the industry has evolved into a sophisticated sector that is heavily regulated by national and European standards. The modifiers used take many different forms: polymers, latex, and many chemical additives. Determining how modifiers actually affect the performance of a mixture and establishing construction quality control procedures for these modifiers can be extremely difficult. In the past these difficulties have caused many specifying agen
