When to Use What Grade of Asphalt and Why

chine mixing with very fine sands in stabilization work. RC-2 is also used as a tacking asphalt prior to resurfacing. More often this material is used for road mixing of finely-graded aggregates such as sands and densely-graded sand-gravel or crushed-stone mixtures. This grade is especially well adapted to machine mixing of fine sands.
