Fine Grading for Pavement ConstructionMentor

A pavement aggregate base is most commonly 'roughed' in with a dozer. In theory, pavement bases more than 6″ in thickness should be compacted in more than one lift, as roller compaction efforts are really only effective to a 4-6″ depth depending on the machine size, weight, and vibratory capability.
