Specifying some minimum percent of the maximum unit weight has gained acceptance with many specifying agencies.

Specifying a percentage of the maximum unit weight.

Establishing a value based on results achieved on a project-site test strip.

Specifying a percentage of the unit weight from the laboratory mix design.

Some of the more common approaches include: There are several ways to establish density targets. Therefore, the maximum size aggregate can be as much as 80 percent of the lift thickness. Proper placement becomes a problem in lifts thicker than 6 or 8 inches.įor open-graded mixes, compaction is not an issue since it is intended that these types of mixes remain very open.

Generally, lift thicknesses are limited to 6 or 8 inches. When pneumatic or vibratory rollers are used, the maximum thickness of lift that can be compacted is almost unlimited. When static steel-wheeled rollers are used, the maximum lift thickness that can be properly compacted is 3 inches. The maximum lift thickness is dependent also upon the type of compaction equipment that is being used. Therefore, the desired lift thickness can direct the decision on nominal aggregate size to use. Minimum lift thickness should be at least 3 times the nominal maximum aggregate size to ensure aggregate can align themselves during compaction to achieve required density and also to ensure mix is impermeable. It does not store any personal data.Nominal aggregate size dictates lift thickness.
