How do you test for bitumen?
Centrifuge Method 2. The bitumen content obtained as a result of the bitumen extraction test is calculated and reported as follows:- Bitumen content (grams) =( W1-(W2+W3))/W1 Where, W1 = weight of the sample test portion in grams W2 = Weight of the extracted mineral aggregate in grams. In the standard test for bitumen content (ASTM D4), a small sample of about 2 g of the asphalt is dissolved in 100 ml of carbon disulfide and the solution is filtered through a filtering mat in a filtering crucible.
