THEORETICAL BITUMEN CONTENT
Theoretical Bitumen % required for mix as per ''Asphalt Mix Design Methods MS-2''
P = 0.035a + 0.045b + Kc + F
P = 5.18
a= 67.06
b= 28.74
c= 4.20
K= 0.20
F= 0.70
Where:
P = approximate asphalt content of mix,percent by weight of mix
a = percent of mineral aggregate retained on 2.36-mm sieve
b = percent of mineral aggregate passing the 2.36-mm sieve and retained on the 75-μm sieve
c = percent of mineral aggregate passing 75-μm sieve
K = 0.15 for 11–15 percent passing 75-μm sieve
0.18 for 6–10 percent passing 75-μm sieve
0.20 for 5 percent or less passing 75-μm sieve
F = 0 – 2.0 percent. Based on the absorption of light or heavy aggregate, in the absence of other data, a
value of 0.7 is suggested.
