31) Line 3, G 3 , specific gravity of filler, from previous experiments, and P 3 is the percent of filler in the total mix = weight of filler / (weight of total aggregate + weight of asphalt used). 32) Line 4 = P s , percent of total aggregate in the total mix = weight of total aggregate / (weight of total aggregate + weight of asphalt used). 33) Line 5 = G b , specific gravity of asphalt, and P b is the percent of asphalt in the total mix = weight of asphalt / (weight of aggregate + weight of asphalt). 34) Line 6 = G s b , bulk specific gravity of total aggregate = (P 1 + P 2 + P 3 ) / (P 1 /G 1 + P 2 /G 2 + P 3 /G 3 ). 35) Line 7 = G se , effective specific gravity of total aggregate = weights of all aggregate compositions / volume of all aggregate composition. 36) Line 8 = G mb , bulk specific gravity of compacted sample = part 1, column 8. 37) Line 9 = G mm , maximum specific gravity of mix = 100 / (P s /G se + P b /G b ). 38) Line 10 = P ba , absorbed asphalt by percent of aggregate weight = 100 * (G se G sb ) * G b / (G se * G sb ). 39) Line 11 = P be , effective asphalt content by percent of total weight = P b – (P ba * P s ) / 100. 40) Line 12 = VMA, void in mineral aggregate in mix, % = 100 * (G mm – G mb ) / G mm . 41) Check: G se > G sb > G mm > G mb . 7

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
