The Effects of Added Softening Agents upon the Behavior of Cold Recycled Asphalt Mixtures

摘要

This report presents the results of a study that dealt with the long-term behavior of recycled mixtures especially when the recycling is done cold. The long-term properties of laboratory specimens prepared with different softening agents were evaluated by means of a creep test. A design procedure for cold recycled mixtures is proposed which recommends that blending curves be developed and that a creep test be used to determine mixture properties over a period of time.
