Abstract

Increased popularity of foamed bitumen as a stabilizing agent in recent years has resulted in a necessity of research into the mechanical characteristics of foamed bitumen mixture rather than material itself. The objective of this project is to assess these mechanical properties of foamed bitumen mixtures in terms of variants on bitumen contents and active filler contents. Specifically, a laboratory blend host material was mixed with 0%, 2%, 4% of foamed bitumen and 0%, 1%, 2% of hydrated lime, respectively, by mass of aggregate. Comparisons were drawn by testing typical mechanical properties of Static tri-axial test, Resilient Modulus test and Permanent Deformation test. Test results indicated the basic mechanical properties of foamed bitumen mixtures under Western Australian laboratory conditions. © 2012 Taylor & Francis Group.
