Sma in highway
WebbIt can be used on major highways with heavy traffic volumes. This product provides a rut resistant wearing course and resistance to the abrasive action of studded tires. This application also provides slow aging and good low-temperature performance. SMA is used to maximize the interaction and contact among the coarse aggregate fraction in HMA. WebbStone matrix asphalt (SMA) is a gap-graded HMA (Figure 1) that is designed to maximize deformation ( rutting) resistance and durability by using a structural basis of stone -on-stone contact (Figures 2-6). Because the aggregates are all in contact, rut resistance relies on aggregate properties rather than asphalt binder properties.
