Abstract:

Increasing use of asphalt binders modified with elastomeric or plastic modifiers makes the specification of binders a difficult task. Ideally, a generic specification would allow various suppliers and additives to compete based on expected performance differences in the hot mix pavements resulting from the use of these binders. This paper describes research whose objectives were to investigate unique characteristics of polymer modified hot mix and to determine if there are binder tests and properties which could be used to predict mix performance whether the binders used are conventional or modified. Two mix designs incorporating three conventional asphalts and six different modified asphalts were tested during two phases of testing. The objective was to determine what binder tests had promising correlations with important mix properties. Fraass Point and PVN showed the most promise for controlling temperature susceptibility of the hot mix at low temperatures. Penetration at 25C and force ductility areas, particularly "peak area," showed the most promise for predicting strength properties of mixes. The best prediction of fatigue life and permanent deformation as measured by diametral testing resulted from a combination of penetration at 25C and force ductility area values as independent variables in multiple regression analysis.
