Example Problem - Answers Percent Effective Asphalt Binder - P be P be = P b - ( P ba * P s ) 100 Where: P b = Percent asphalt binder in total mix P ba = Percent Absorbed Asphalt Binder in total mix = Percent aggregate in total mix P s Based on the information known: P b = 5.0 % P ba = 0.4 % P s = 95.0 % P be = 5.0 - ( 0.93 * 95.0 ) 100 = 4.1 % Guarin@kth.se
Example Problem - Answers Percent Voids in Total Mix - Va Va, % = 100 * ( G mm - G mb ) G mm Where: G mm = Theoretical Maximum Specific Gravity <strong>of</strong> mix G mb = Bulk Specific Gravity <strong>of</strong> mix Based on the information known: G mm = 2.521 G mb = 2.421 Va = 100 * (2.521 - 2.421 ) 2.521 = 4.0 % Guarin@kth.se
