360.3(c) 360.3(m) material so that combining with aggregate produces a completed mixture. Coat the aggregate with the asphalt material to form a film of adequate thickness to provide the required binding properties. Produce ATPBC at a temperature below 32 0F that also provides suitable viscosity for adequate coating of aggregate particles, and that does not cause segregation of asphalt and aggregate during transportation. Do not stockpile ATPBC. The ATPBC must be placed within 8 hours from when it is made.
Use steel -wheel power rollers with a manufacturer’s certified metal weight of 8 tons to 10 tons.
Use a slip form paver, as specified in Section 413 .3(e), or a mechanical spreader. Spread and strike off the mixture for the entire lane width or as much lane as practical. Place the mixture in maximum 4- inch compacted lifts. Adjust screed assemblies to provide the cross section and depth indicated. Construct the profile to the design grade line. Use fully automated sensors to control profile and transverse grade. Allow the mixture to cool to 100F before placing subsequent layers or pavement courses. Perform handwork at locations directed by the Representative.
Perform rolling as soon as the mat has cooled sufficiently to avoid shoving or lateral movement of the ATPBC. Seat ATPBC using a n 8-ton to 10- ton, steel -wheeled roller, or vibratory roller operated in the static mode only. Compact ATPBC by applying four roller passes. One roller pass is defined as one trip of the roller in one direction over any one spot. Additional passes are allowed only to eliminate any surface irregularities, or creases. Do not c ompact the material to the point that it is not free draining or the aggregate is crushed.
placed by 1 inch to 2 inches. Maintain the uniform uncompacted depth adjacent to a compacted lane necessary to provide a smooth joint after compaction.
interruption occurs in ATPBC paving operations, install a temporary vertical bulkhead to form a straight transverse construction joint. The joint must be the full depth and width of the ATPBC. Instead of a temporary bulkhead, the Contractor may saw construction joints.
