A disadvantage to this method is that the accuracy is highly dependent on how well the percentage of absorbed asphalt could be estimated. Determining the right Gsb-rap is important because an artificially high value has the potential to decrease the effective asphalt binder content in the mix, and thus reduces durability of the mix.
