coarse and fine aggregate gradation in states

COARSE- VERSUS FINE-GRADED SUPERPAVE .

Both coarse- and fine-graded hot-mix asphalt mixtures can be designed within the gradation control points recommended in Superpave (Registered trademark) mix design. Some states have begun to specify only coarse-graded mixtures (below the restricted zone), whereas other states are specifying only fine-graded mixtures (above the restricted zone). A study was conducted to compare coarse .
