  • Abstract:
    Because some of the Department's bituminous overlays have displayed cracking in the short period of three to five years, and because few if any density controls are exercised in maintenance plant mix schedules, the Bituminous Research Advisory Committee recommended that the Research Council undertake a study to determine the compaction level generally being attained on maintenance overlays. Data taken over the 1975-76 paving seasons, indicate that the Department's specification requirement is not being met consistently. For example, in 1976 only 16% of the maintenance projects tested met the specification. Because of these poor density results, it is recommended that nuclear control strips be used on maintenance overlays as they are on new construction.
