The drawing shows a multi-layer asphalt pavement section consisting of two layers of 1-inch HMA S0.5 over a 5-inch layer of HMA S1.0 in two equal courses. Below the asphalt layers is a 12-inch densely graded crushed stone base (or 20 inches in rock cut) resting on a prepared subgrade. Notes indicate the pavement structure is obtained from the CTDOT MTG pavement design catalog for specific route conditions.
