Spread in accordance with Section 39 of the Standard Specifications. Cover all loads with tarpaulin or other material during transportation. 3.6.3 Compaction: Initial or breakdown rolling and the final rolling of the uppermost layer of the asphalt concrete shall be in accordance with Section 39 of the Standard Specifications. Compaction by vehicular traffic shall not be permitted. 3.6.4 Joining Pavement: Carefully make joints between old and new pavements or between successive days' work made in such manner as to ensure a continuous bond between old and new sections of the course. Expose and clean edges of existing pavement. Cut edge to straight, vertical surfaces. Paint all joints with a uniform coat of tack coat before the fresh mixture is placed.
