Voids Filled with Asphalt VFA is the percent of VMA that is filled with asphalt cement VFA = 100 x VMA - V a VMA Given that Va = 4.7 , VMA = 14.6 VFA = 100 X 14.6 – 4.7 14.6 = 68 % Guarin@kth.se
Percent Binder Absorbed P ba is the percent of absorbed asphalt by wt. of aggregate P ba = 100 ( G se - G sb G sb G se ) G b P ba = 100 ( 2.750 - 2.657 2.750*2.657 ) 1.03 P ba = 1.32 % Guarin@kth.se
