Characterisation of Polymer Modified Asphalt Binders for Roads and Airfields


This paper elaborates on the characterisation of styrene butadiene styrene, ethyl vinyl acetate, low density polyethylene, polypropylene wax and hydroxylterminated polybutadiene modified asphalts by penetration temperature sensitivity, thermogravimetric analysis, penetration ratio, cohesion, adhesion, stability, tensile strength and flexural fatigue test. The benefits obtained by the modification of asphalt with polymers are improvement in quality of asphalt as defined by increased cohesion, adhesion, elastic recovery and reduced temperature sensitivity. The significant characteristics of polymer modified asphalts are high stability, tensile strength, stiffness and extended fatigue life. The effects of wax in waxy asphalts is reduced by incorporation of polymers.
