The objective of this study was to assess the impact of aging on high polymer (HP)-modified
asphalt binders when compared with conventional polymer-modified asphalt (PMA) binders …

Polymer modification of asphalt binders has progressively become more common over
recent decades. Styrene-Butadiene-Styrene (SBS) is a well-recognized elastomer that has …

The objective of this paper was to provide information on the state of the practice for using
high polymer-modified (HP) asphalt concrete (AC) mixtures in the United States (US) and …

Florida Department of Transportation uses the 1993 AASHTO guide to conduct new and
rehabilitation designs for all the state's flexible pavements. Based on previous experience, a …

Resurfacing a moderately deteriorated Portland cement concrete (PCC) pavement with
asphalt concrete (AC) layers is considered an efficient rehabilitation practice. However …

This study was conducted to assess high polymer modified asphalt binders including a corn
oil-based softening agent (SA) and their impact on the cracking performance of mixtures in …

Extensive laboratory performance testing and advanced statistical analyses led to the
determination of a fatigue-based structural layer coefficient of 0.54 for high polymer-modified …

This paper presents a generalized framework for determining mechanistically informed layer
coefficients (a-values) for asphalt mixtures in the AASHTO empirical pavement design …

This paper presents the validation process for the structural layer coefficient determined
mechanistically for high polymer (HP) asphalt mixtures (ie, 0.54) through full-scale …
