design of normal concrete mixes,the water/cement ratios referred to in this publication are the ratios by mass of free-water to cement in the mix and these, as well as the free-water contents, are based on the aggregates being in a saturated surface-dry condition. 1.2.4 types of aggregate early mix design methods used in the uk [18,19] classified aggregate..a method for consistent classification of materials for,• mix design component: this vital element of bitumen stabilization is addressed in a separate study, and is thus not covered by this memorandum. the findings of the mix design component of the study are expected to be published during 2008, and will be used to refine the classification method so that.
