Table 4-8 presents the requirements for flat and elongated particles. Clay Content The presence of dust or clay coatings on aggregates can prevent the asphalt binder from prop- erly coating the aggregates within an HMA. This can lead to water penetrating the asphalt binder ï¬ lm and, therefore, stripping of the asphalt binder from the aggregate.
