Influence of Polymer Modified Binder Content from RAP on Stone Mastic Asphalt Rutting Resistance

Adam Liphardt , Piotr Radziszewski

Abstract

Properties of hot mix asphalt with reclaimed asphalt pavement (RAP) mostly depends on RAP properties, especially RAP binder. It is assumed that binder from RAP is usually stiffer than virgin binder because of exploitation aging process. Use of RAP may cause stiffening of asphalt mix and improvement of rutting resistance. This paper demonstrates results of wheel tracking tests of stone mastic asphalt. Analyzed asphalt mixes were designed with six different content of RAP. Penetration and softening point of binder mix was determined and binder replacement factor for asphalt mixes was calculated. Analyses of wheel track tests with comparison to binder properties shown that increasing amount of modified binder from RPA occurs in increasing rutting resistance of asphalt mixes.
