c. Following compaction of longitudinal joints and edges, rolling shall start longitudinally at the sides and gradually progress toward the center of the parking lot. The rollers shall move at a uniform speed with the drive wheels nearest the paver.

d. If rolling causes displacement of the material, the affected areas shall be loosened at once with lutes or shovels and restored to the original grade of the loose material before being re-rolled.

e. Heavy equipment and/or rollers will not be permitted to stand on the pavement until it has been thoroughly compacted and cooled.

f. Breakdown rolling shall immediately follow rolling of the longitudinal joints and edges. Rollers shall be operated as close to the paver as necessary to obtain the required density without undue placement.

g. The second rolling shall be accomplished with pneumatic tire or tandem rollers as specified herein. The second rolling shall follow the breakdown rolling as closely as possible and while the mix is still at a temperature which will allow for proper compaction.

h. Finish rolling shall be accomplished while the material is still warm enough to allow for removal of the roller marks.

i. Areas which are not accessible by the rollers shall be compacted with a trench roller or by hand.

8. Traffic Control:

When working, the Contractor shall provide appropriate barricades, warning devices, and/or flagmen as necessary to protect workers, equipment, and construction areas.

Follow the Manual of Uniform Traffic Control Devices

(MUTCD).
