Example Problem Let’s assume we have a compacted HMA mixture with the following properties. Bulk Specific Gravity of the Mixture - G mb = 2.421 Theoretical Maximum Specific Gravity - G mm = 2.521 Asphalt Binder Specific Gravity - G b = 1.03 Asphalt Content - P b = 5.0 % (by mass of total mix) Guarin@kth.se
Example Problem Let’s also assume that three stockpiled aggregates were used to manufacture this HMA mixture. The percent of each aggregate and the Bulk Specific Gravity (G sb ) for each is as follows: Aggregate % of Total Aggregate G sb A B C 50 % 25 % 25 % 2.695 2.611 2.655 Guarin@kth.se
