Performance of Crushed-Stone Base Courses
The crushed-stone base sections were found to give excellent performance when covered with asphalt con e rete 3. 5 in. ( 89 mm) thick. Good perfor mance of the engineered crushed-stone base is attributed to (a) a uniform, high degree of density (100 percent of AASHTO T-180), (b) use of a well-graded crushed stone with
