The standard categorizes minimum and maximum percentages of voids filled with binder (VFB). The following are the available categories of requirements and their denotations:
• Minimum percentage of VFB range from 71 to 86% in increments of 3% (i. e., VFBmin= 71, 74, 77….)[78] plus VFBminNR, where VFBminNR means no requirement.
• Maximum percentage of VFB range from 77 to 92% in increments of 3% (i. e., VFBmax= 77, 80, 83.)f plus VFBmaxNR, where VFBmaxNR means no requirement.
14.5.5 Binder Draindown
Tests of binder draindown should be performed according to EN 12697-18. Available categories of the maximum permitted binder draindown from the SMA mixtures are D03, D06, D10, and DNR, where DNR means no requirement. However, EN 13108-20 does not indicate directly which method of EN 12697-18 should be used—basket or Schellenberg (see Chapter 8).
