Abstract:There is no standard design procedure available for black base mixes containing aggregates larger than 1" (25.4 mm) This investigation dealt with the use of stability testing equipment similar to that used in the design of surface mixes and development of a compaction procedure for 6" (152. 4 mm) diameter specimens. A compaction procedure was developed that could be used with slight modification to duplicate field densities. The trends of the VTM and VFA cut, yes appear promising as an indicator of the proper asphalt content; however, the inherent variability of the stability measurement eliminates it as a design criterion.
