3.02 PLACING THE MIX

A. The mixture shall be placed in one uniform lifts to provide a nominal compacted thickness as specified on the drawings. Placing the mixture shall be a continuous operation. If any irregularities occur, they shall be corrected before final compaction of the mixture.

B. The temperature of the mix at lay-down shall be a minimum of 230o F when the ambient temperature is above 60o F and 250o F when ambient temperature is below 60o F.

C. Until bituminous mixture is compacted, no hauling over placed surface will be permitted.

3.03 COMPACTING THE MIX

A. The mix shall be compacted immediately after placing. Initial rolling with a steel-wheeled tandem or steel-wheeled vibratory roller shall follow paver. If needed, rolling with a pneumatic-tired roller shall be done immediately behind the initial rolling. Final rolling with a steel-wheeled roller shall eliminate all rolling marks. In small areas a vibrating plate compactor or a hand tamper shall be used to achieve thorough compaction.

B. Final rolling and density of the hot plant mix bituminous pavement shall be obtained prior to the mixture reaching a minimum temperature of 185 degrees F.

C. The patching mixture shall be compacted to produce a tight surface conforming to the adjacent pavement area.
