Dynamic Viscoelasticity of Modified Asphalt

Journal of The Japan Petroleum Institute, 1972
The physical properties and the dynamic viscoelasticity of the modified asphalt were investigated and the following results were obtained.(1) The asphalt modified by the catalytic semiblowing has the gel type colloid structure as expressed by As/P, where As is the asphaltene content and P is the state of peptization of asphaltene micelle.

Polyphosphoric acid modified asphalt: proposed mechanisms

, 2006
Asphalt binders have been chemically modified with polyphosphoric acid (PPA) to improve high temperature rheological properties without adversely affecting low temperature rheological properties since the early 1970's. More recently, PPA has been used in
