1. Complete compaction before mix temperature cools to 185 deg F.

9. Breakdown Rolling: Complete breakdown or initial rolling immediately after rolling joints and outside edge. Examine surface immediately after breakdown rolling for indicated crown, grade, and smoothness. Correct laydown and rolling operations to comply with requirements.

10. Intermediate Rolling: Begin intermediate rolling immediately after breakdown rolling while hot-mix asphalt is still hot enough to achieve specified density. Continue rolling until hot-mix asphalt course has been uniformly compacted to the following density:

a. Average Density: 96 percent of reference laboratory density according to ASTM D

6927 or AASHTO T 245, but not less than 94 percent nor greater than 100 percent.

b. Average Density: 92 percent of reference maximum theoretical density according to

ASTM D 2041, but not less than 90 percent nor greater than 96 percent.

11. Finish Rolling: Finish roll paved surfaces to remove roller marks while hot-mix asphalt is still warm.

12. Edge Shaping: While surface is being compacted and finished, trim edges of pavement to proper alignment. Bevel edges while asphalt is still hot; compact thoroughly. Remove paved areas that are defective or contaminated with foreign materials and replace with fresh, hot-mix asphalt. Compact by rolling to specified density and surface smoothness.

F. Protection: After final rolling, do not permit vehicular traffic on pavement until it has cooled and hardened.

13. Barricades: Erect barricades to protect paving from traffic until mixture has cooled enough not to become marked.
