Using the ASTM C127 prоcedure fоr determining the specific grаvity аnd аbsоrption of coarse aggregates, answer Questions 1-4 based on the provided sample data: A representative sample of coarse aggregate has the following weights: A (Dry weight): 2030.9 grams B (SSD weight): 2044.9 grams C (Submerged weight): 1304.3 grams Using the formulas below, calculate each property: Bulk Dry Specific Gravity = A(B–C)frac{A}{(B – C)} Bulk SSD Specific Gravity = B(B–C)frac{B}{(B – C)} Apparent Specific Gravity = A(A–C)frac{A}{(A – C)} Absorption (%) = (B–A)A×100% 1- Bulk Dry Specific Gravity equals:

B) They are based on the original foundation dimensions B and the depth Df. C)They only depend on the eccentricity e. D) They are not relevant to Meyerhoff's method.
