The effects of added softening agents upon the behavior of cold recycled asphalt mixtures
Abstract
The long-term behavior of recycled mixtures, especially when the recycling is done cold is reported. 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.
