SMA mix design via binary packing triangle concepts
One of the principal requirements for stone mastic asphalt mix design is the provision of stone on stone packing for the aggregates and sands that will provide the intended rutting resistance for this mix. This paper provides a rational mix design procedure for SMA based on particle packing triangle concept through a binary or two component design procedure with added consideration to the effect of fillers. The packing of materials is based in the classic work of Furnas, Powers and Lees, including the fixed binder work of Heukelom. The materials are combined in such a manner that it’s interaction with the mastic ensure voids are at the required design level. Adjustments can be made to material combinations in an educated manner replacing the usual adhoc methods currently available. A practical application of the packing theory is provided demonstrating the benefits of the method.
