Structural Coefficient for High Polymer Modified Asphalt Mixes

The objective of this project is to determine the structural coefficient for asphalt mixes that contain high polymer modified binder (specified by Florida Department of Transportation (FDOT) as PG 76-22 (HP) and containing approximately 7.5% Styrene-Butadiene-Styrene (SBS) or SB polymer). With this determination, the Flexible Pavement Design Manual will be modified to adopt the structural value for mixtures containing this binder type.
