1. Specifications on a job require a fill using borrow soil to be compacted to 95% of its standard Proctor maximum dry density. Tests indicate that this maximum is 124 lb/ft³ when dry. The soil now has 12% moisture. The borrow material has a void ratio of 0.6 and a solid specific gravity of 2.65. What is the minimum volume of borrow soil required per 1.0 ft³ of fill volume? Equations: P = M₁ V₁ ; Pa M. S V₁ ;Ps = M. V. -; Pw = M. W V ·;e= ; n = V. V V₁ .: S M W = wx100%; G = -; Constants: pw = 1000 kg/m³; yw-62.4 pcf M Pw = V. W V, -× 100%;
