Study of Factors Affecting Crushed Stone Base Performance
Twelve full-scale pavement sections were tested to failure in a special laboratory facility under closely controlled environmental conditions. Seven of the pavement sections were loaded to over one million repetitions, and five sections to over two million repetitions. A 6.5 kip (29 kN) uniform, circular loading was applied to the surface, and systematically moved to prevent a punching failure. A complete series of laboratory tests including fatigue and rutting were performed to characterize the materials. Pavements tested consisted of five conventional sections having crushed stone bases, five full-depth asphalt concrete sections, and two inverted sections. The inverted sections consisted of a crushed stone base sandwiched between a lower cement stabilized layer and an upper asphalt concrete layer. Conventional sections were tested having two thicknesses of base and three base gradations.
