Polyphosphoric Acid Modified Binders
This report provides a general overview of polyphosphoric acid modified binder. A modification mechanism between the acid and binder was proposed. The addition of acid was found to change the chemical compositions of the binder noticeably. The…
Determination of Permanent Deformation and Resilient Modulus Characteristics of Unbound Granular Materials Under Drained Conditions
This method covers the determination of both the permanent deformation and resilient modulus of unbound pavement materials with a maximum particle size not exceeding 19 mm using repeated load triaxial equipment incorporating, static confining…
