AN INTEGRATED APPROACH FOR DETERMINING ADDITIVE REQUIREMENTS IN HOT MIX RECYCLING. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN

Additives are needed in hot mix recycling in order to rejuvenate aged binders when this cannot be accomplished by using only new penetration grade bitumens. However, the use of additives can have significant adverse effects on the behaviour of asphalt mixes. Despite much progress in this area, questions relating to aspects such as time-dependency and chemical compatibility remain largely unanswered. The paper examines some of the earlier work undertaken in the development of additives and evolution of specifications, and the subsequent research aimed at developing a comprehensive method for the effective determination of the need, correct type and amount of additive for particular recycling situations.
