Abstract:

Segregation in asphalt pavement can manifest either as variation in the gradation of the aggregate in the asphalt mix (gradation segregation) or as variation in the temperature (thermal segregation), and both may occur together. Perhaps the primary cause of segregation is improper handling during mixing, transportation, and placement of the asphalt, which can occur at the silo or at the end of the load or elsewhere in the paving process. This report includes a literature review, national survey of state DOTs, and review of construction and materials specifications to assess the current state of the practice in mitigating segregation in asphalt pavement. Recommendations for possible implementation are given.
