Abstract

Curing

Foamed bitumen

Foamed bitumen base

Foamed bitumen stabilization

Foamed bitumen stabilization is well-established as a beneficial technology for the improvement of existing pavement materials and for expedient pavement construction or rehabilitation. Laboratory curing indicative of in-pavement conditions is crucial to effective foamed bitumen stabilized material characterization for pavement design, with significant project and pavement lifecycle cost implications resulting from laboratory mix design that does not represent actual pavement behavior. This research compares Australian foamed bitumen base laboratory curing practice to a simulated in-pavement condition and concludes that the accelerated laboratory curing was more representative of 20–30 days of in-pavement curing, rather than the intended medium (3–6 month) term curing condition. It is recommended that new laboratory curing protocols be developed to better represent typical in-pavement curing conditions.
